RED – RAPT Pill Digital Hydrometer & Thermometer

Description

The RAPT Pill RED digital hydrometer extends the gravity measurement range to 1.130 SG, making it the go-to floating hydrometer for high-gravity beers, ciders, wines, and spirit washes where the standard Pill Yellow tops out. Colour-coded red so you can instantly tell your high-gravity sensor apart in a multi-fermenter brewery, it uses the same Wi-Fi and Bluetooth connectivity, the same free RAPT Portal software, and the same capsule form factor as the Pill Yellow — so any accessories you already own carry across. Stocked in Australia at Yeast Platform for fast local dispatch.

Extended Range for Big Beers and Washes

Imperial stouts, barleywines, high-ABV meads, turbo washes, and wine fermentations routinely start above 1.090 OG and can push into territory where the standard Pill Yellow is less accurate or at its ceiling. The RAPT Pill RED is calibrated for this range, logging accurate gravity readings through the entire fermentation arc of high-gravity recipes. It streams data to the RAPT Portal at configurable intervals (15 minutes by default), letting you track the rapid early-fermentation gravity drop and confirm attenuation in high-ABV batches without pulling a single sample.

Shared Ecosystem With the Pill Yellow

Because the Pill RED uses the same RAPT Portal account and the same Micro-USB charging standard as the Pill Yellow, adding it to a mixed-gravity brewery is seamless. Both Pill models appear on the same dashboard, with colour-coded fermentation curves that make it easy to monitor a session lager and an imperial stout in parallel. If you already own the Wireless Charging Kit, it charges the Pill RED without any modification. The Bluetooth Thermometer and WiFi Temp Controller integrate identically regardless of which Pill model you’re running.

Australian Home Brewing Context

For Australian brewers making high-gravity beers during summer — when fermentation temperatures can spike and gravity drops can be dramatic — the continuous logging the RAPT Pill RED provides is invaluable. Set up a portal alert for when gravity drops below your target krausen point and trigger your diacetyl rest remotely without being in the same room as your fermentation fridge. Pair with the RAPT WiFi Temperature Controller to manage the full fermentation profile of your biggest batches.
