Yellow RAPT Pill – Hydrometer & Thermometer (Wifi & Bluetooth)

Yellow RAPT Pill – Hydrometer & Thermometer (Wifi & Bluetooth)

The RAPT Pill allows true real-time specific gravity and temperature logging and control via wifi/BlueTooth integration with the RAPT fermentation chamber (KL15813), RAPT mobile app or RAPT IoT.

The RAPT Pill allows you to instantly read and log the specific gravity and temperature of your fermentation via the RAPT mobile app on your compatible Android smartphone or tablet, Apple iPhone/iPad or via the RAPT IoT hub on your Windows or Mac Computer.

The RAPT Pill has a long battery life and can last 2-5 months between charges when utilising Wifi. If only using Bluetooth the battery can last 2+ years before needing to be recharged. The RAPT Pill has a USB-C charging port on the circuit board allowing fast charging from any USB-C cable.

The RAPT Pill is universal and is compatible with most standard carboys, Cornelius kegs, stainless steel fermenters, and pressurisable fermenters.

Pill Housing Design

The RAPT Pill housing boasts many advantages compared to other wireless hydrometers such as:

1. Made from strong BPA Free Nylon 12 and Polyketone(POK)
   Both the clear Nylon 12 and Polyketone plast are food grade, FDA approved, BPA (and free of other types of bisphenol).  These are also plasticiser and phthalate-free.  They also contain no endocrine disruptors making them a much better choice than polycarbonate that is used in other products.  Nylon 12 and POK are also high temperature resistant, chemically resistant and extremly robust.
2. Greater ergonomics – The shape of the RAPT Pill has been designed for improved usability compared to other wireless hydrometers such that the Pill separates into two pieces at the midline of the Pill rather than requiring a difficult to remove end cap to be unscrewed.
3. Sanitary design – The RAPT Pill has no exposed thread and a double o-ring seal which allows for a water-tight seal with reduced risk of infection.
4. Less susceptible to error – The larger housing of the RAPT Pill compared to other wireless hydrometers means that the gravity logging is less susceptible to error from krausen, hops or CO2 bubbles from fermentation.

Different housing colours are sold separately on the website allowing customisation of your RAPT Pill. The colours available include:

• RAPT Pill – Red Housing
• RAPT Pill – Blue Housing
• RAPT Pill – Green Housing
• RAPT Pill – Yellow Housing – All units come with Yellow pre-assembled

Specifications:

The RAPT Pill is approximately 37mm x 125mm – compact enough to fit almost anywhere!

What is RAPT?

The RAPT IOT Hub is a free service whereby any RAPT enabled product can both log and store data to the hub where you can conveniently access this data.  The RAPT hub can also allow you to control your devices remotely giving you absolute control of the device irrespective of where you are.  The RAPT portal enables you to make complex temperature profiles that involve different temperature settings over time meaning you can start/run a temp profile giving you a set and forget experience.  The RAPT portal also controls the alert/notification process for you so you can receive email notification in the off instance that something doesn’t go to plan.

There is no limit to the number of RAPT devices you can connect the RAPT IOT Hub. This is in contrast to other popular wireless hydrometers where you are limited by the number of hydrometers you can connect to an app.

Please note: The RAPT Pill is fully wifi and Bluetooth capable. At present it can be integrated fully with wifi. Bluetooth integration will be enabled with a later firmware update.

Antenna Update
The RAPT Pill has been designed so you can plug in an optional upgradable external antenna.  With that said we have done a significant amount of optimisation with the printed PCB antennas to improve gain.  This RF laboratory testing and optimisation was completed in late 2021 and was implement on all PCB board versions 2.0 and above.  Through vigorous testing we have concluded that the on board printed PCB antenna is better than any other external antenna that we have found so far.  So until we find better external antennas we have ceased the sale of these inferior antennas.  If however you would like to experiment with external antenna the boards are fitted with a socket for this.  If you find a particularly good antenna please let us know and we will send it off for testing.  If we find one that is significant better we will also make this available to our customers too.
