Made in Japan
Manufacturer: Watanabe Electric Industry Co. Ltd
Model: RHM

RHM is an indoor resistance thermometer that is mounted on a wall and measures the temperature of a space. Because flame-retardant ABS resin is used, temperature measurement up to 120°C is possible. In addition, chlorine countermeasures and drip-proof specifications can be produced, so it can be used not only for general air conditioning but also for indoor pools, bathrooms, dry saunas, etc.
