The RAPT Pill Hydrometer & Thermometer is an advanced but affordable WiFi and Bluetooth Hydrometer and Thermometer. Designed from the ground up to be simple to use, but with an advanced feature set and a simple, sanitary design. The RAPT Pill Hydrometer & Thermometer will integrate perfectly with a RAPT Fermentation Chamber or RAPT Temperature Controller for fermentation control using time, gravity or gravity velocity to control your fermentation.
The RAPT Pill Hydrometer & Thermometer provides real time gravity and temperature data and logging from inside your fermenter. The sanitary design is easy to clean, chemically resistant and robust. The RAPT Pill Hydrometer & Thermometer comes complete with a rechargeable Li-ion 18650 battery that will provide months or even years of battery life*
*Battery life depends on Bluetooth or WiFi connectivity and telemetry interval – expect 12 months battery life when connected by Bluetooth with 60 minute telemetry intervals (Smart Mode disabled)
Important Note: Always charge the RAPT Pill for at least 24 hours before first use. This will ensure it is fully charged. If the battery is not sufficiently charged initially it may cause connectivity or registration issues.
RAPT Pill Hydrometer & Thermometer Features
Bluetooth Connectivity
The RAPT Pill Hydrometer & Thermometer can be connected to a RAPT Fermentation Chamber or RAPT Temperature Controller via Bluetooth. This is the ideal way to use a Pill as it will send temperature, gravity and gravity velocity data directly to RAPT device, allowing for incredibly precise and powerful fermentation control. Using the RAPT Brew App, the Pill can be calibrated for gravity or temperature directly in the fermenter over Bluetooth (Firmware 2.0.0 or later required, Smart Mode enabled)
Using Gravity Velocity allows for amazingly precise but completely automated fermentation control – there is nothing else like this on the market!
See video below on how to do this:
Network Capable
The RAPT Pill Hydrometer & Thermometer will also connect directly to a WiFI network (required). Once connected, you can access real time telemetry anywhere in the world as long as you have internet access! NOTE: Requires a 2.4gHz network
Easy and Accurate Calibration
The RAPT Pill can be calibrated using one or two point calibration in seconds, even if the RAPT Pill is currently inside a fermenter! Simply use Shake To Wake, connect and calibrate in seconds. Every RAPT Pill features highly sensitive and accurate accelerometers in 3 axes ensuring highly accurate gravity accuracy. (Requires minimum firmware 2.0.0, Smart Mode active)
Pill Housing Design
The RAPT Pill Hydrometer & Thermometer boats many advantages over other wireless hydrometers – it is designed from the ground up with brewers in mind!
1. Made from Nylon 12 and Polyketone (POK). Food grade, FDA approved, BPA, bisphenol, plasticiser and phthalate-free. Nylon 12 and POK are highly chemical and temperature resistant as well as extremely robust. 2. Ergonomic and Sanitary. With a single, centered thread and a seamless design that includes a silicon and EPDM double o-ring design this is easy to clean and sanitise 3. More Accurate: The large, smooth housing means the RAPT Pill is less susceptible to error from krausen, hops or CO2 bubbles from fermentation. 4. Multiple Housing Colours available: If you have multiple RAPT Pills, simply purchase different coloured housings to easily differentiate them (or to bling them up!)
RAPT Pill - Red Housing RAPT Pill - Blue Housing RAPT Pill - Green Housing RAPT Pill - Yellow Housing All units come with Yellow Housing pre-assembled
Wireless Charging Option
All Rapt Pills can be retrofitted with the Wireless Charging Upgrade Kit. This is highly recommended as it means you will not need to calibrate the Pill after charging – calibration is recommended after opening the Pill housing. A complete, assembled Wireless Charging RAPT Pill Hydrometer & Thermometer is also available.
Specifications
*Accuracy: +/- 0.002 SG points Temperature Range: -20°C(-4F) and up to 60°C(140F) Pressure: 0-5bar Battery: Li-Ion 18650 (we use the EVE Brand) Size: 37mm Diameter x 125mm Temperature Accuracy: +/- 0.2°C (0.36°F)
*Accuracy may be affected if solids are stuck to the outside of the pill hydrometer. If you shake the fermenter from time to time this generally helps to wash hops and solid chunks of krausen off the body of the Pill and through the fermentation these will generally drop to the bottom of the fermenter.
RAPT Brew App & RAPT Brew Web App
All RAPT Devices work through the RAPT Brew App. The RAPT Brew App is a native IOS and Android App with easy to use but amazingly powerful features. Setup complex Automations to control fermentation and brewing. Monitor your beer remotely every step of the way. Automatically carbonate using the RAPT Spunding Valve, or track your consumption and make sure your kegs never run dry with the RAPT Laser Level Sensor.
The RAPT ecosystem includes products that automate every step of the brewing process, and also bring fantastically powerful control/ Using a RAPT Pill in conjunction with a RAPT Fermentation Chamber or Temperature Controller unlocks the ability to control your fermentation using real time gravity data – ensuring a fast, clean and complete fermentation every time!
The power of RAPT can be accessed anywhere you have internet access, using the RAPT Brew App or the RAPT Brew Web App (coming very soon)

Reviews
Works well…once you get it set up
"Overall good product, setting it up was painful, instruction/guidance is light on. You HAVE to charge the battery until it has fully charged and registered itself as charged before it will work, it takes a crazy amount of time to do that, as in over 24 hours. The interface/app is confusing, some things needed to be done on the app (there are 2 of them), some on the web interface (which apparently getting phased out)- nothing was straight forward. Once setup, seems to be quite good."

Rapt pill
"I found registration hard to do I have calibrated the SG but no data on Rapt io portal as yet. I’m still wondering whether this is a worthwhile product. The Rapt Brew App has not found the pill. A work in progress. shouldnt be this hard."
— Robert W. (1/5)
Rapt pil hydrometer
"I gave the pil a poor rating in my previous review but after spending more time to set it up and connect to wifi I have had a success with my 1 st brew. I have spent 1 week controlling my brew from a remote location. To know the SG and temp is a game changer for me. 1 star deleted for hard set up."
— Robert W. (4/5)
I recently purchased the RAPT
"I recently purchased the RAPT Pill from KegLand and have been really impressed with it. The photo shows my full fermentation setup, although the RAPT Controller itself is not pictured. Used together, the RAPT Pill and controller gave me much better visibility and control over fermentation temperature and gravity trends, which made the whole process easier to manage. I used the setup to brew a pretty amazing lager! Clean, crisp, well-controlled and easily one of my best batches so far. Very happy with the product and the results."
— James P. (5/5)
Works great
"Awesome to be able to look at the gravity anytime. Its a little tricky to tighten up at first, had to use some food grade lubricant which helped a lot. Overall worth it."
— Xavier W. (5/5)
Sehr Unzuverlässig
"Leider sendet die Pille manchmal tagelang gar keine Daten, dafür manchmal alle paar Stunden."

Great device for those that love data
"I’m relatively new to brewing. I bought this to simplify SG reading from my pressure fermenter. Once I started using it, I realized how powerful this thing can be. I’m now hoping to use this to standardize my brews, and remove the guess work (and second guessing). It’s a slippery slope - and rapt seem to have most bases covered. On postage - I highly recommend express over standard - it’s much faster."

Q&A
Am I correct in my assumption that data from the RAPT pill is recorded on Kegland server and users view/ download their data from there?
Pretty much! You can access online via the RAPT Portal or the new RAPT Brew phone app
As a home brewer in the States, I was wondering if the RAPT Pill can be used worldwide? Is it compatible with our sometimes different tech standards. Thanks mate
For sure! The Pills just need to connect to a normal 2.4gHz WiFI network.
Hello! Is there any way RAPT PILL could be used with 5 GHz Wi-fi? I received mine as a gift quite a while ago, and didn't notice this detail. Is there any updates coming in near future?
The board can only connect to 2.4gHz networks, sorry. Setting up a guest network often allows a 2.4gHz network!
Hi, Can this be kept in unitanks, and left in under pressue whilst the beer is kegged?
Yes it can! These now have an EPDM seal as well as silicone for better sealing under pressure, as well.
I have just finished my 1st brew using the pill and it worked well with readings matching the manual ones. Trouble is it's continuing to send readings to the app even though its out and stored horizontally (as per instructions to switch off) How do I switch this off between uses?
They definitely go to sleep when horizontal, but they are quite sensitive to movement!
