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.
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:
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
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)
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 Wireless Charging units come with Red Housing pre-assembled
*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.
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)

"This is such a great product for knowing exactly what is going on with the beer. I have it linked to the RAPT temp controller for mindless brewing with excellent results."
"This was my first RAPT purchase but will not be my last. The visibility of the Gravity graduation and abilty to perfectly time the diacetyl rest. has given me some great results. Temp controller will be next purchase or will it a second Pill?"
"This is my 4th Rapt Pill, very happy with all of them"
"I have been using the Pill for almost a year now. In wifi mode in stainless fermenter. As well as in Bluetooth mode to control the RAPT fermentation chamber. Works great and is easy to setup"
"I beleive it will be great to have some functionality on te RAPT portal/cloud to switch on a RAPT PILL transmitter mode: to check/change PILL parameter or do calibartion. As well as please consider option to have access to PILL setting via RAPT portal. PS Automation is really amazing feature! Thanks for that!!!"
"Great bit of kit, being able to just check how a fermentation is going while out of the house is a massive peace of mind, when calibrated properly I've found it to be highly accurate. A very easy purchase if you are wanting to upgrade your brewing process."
"Brilliant bit of kit Follow online instructions and it is amazing Get the wireless one to save you hassle of recalibrating after every charge Linked to my rapt temp controller and love it"
"The PILL is such a wonderful way to see how fermentation is progressing. I really like how I can better control the fermentation of my Kolsch style beer through the automation of the PILL along with my Rapt temperature contoller."
"Got this floating around in a batch right now. Easy to set up and use and I’m not great with technology. Would definitely recommend it"
"Great bit of kit. Pros: once running, amazing information about your ferment. Cons: a bit fiddly to setup first time. Instructions are ok for the main set up, but not great for the pre-setup. Took me a while to realise the wifi pill still had blockers on the battery that you need to remove. Also the housing comes “90” tightened. As a first time user, I had expected the wireless version to come with no need to undo it. Would be good to have those basic instructions come in the box. So - on first set up - open the pill, remove the battery blocker at the terminals, and tighten it up until the final seal is right up to the plastic. Charge for 24 hours then follow the instructions online. From there, you’re good."
