RAPT Pill Hydrometer & Thermometer

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)
