This document describes the features and characteristics of the HMW40U indoor wall-mounted humidity converter, including static capacity polymer film, humidity measurement range of 0-100%RH, and temperature measurement range of -40 to +60℃.
The HMW40 is an indoor wall‑mounted humidity and temperature converter designed for precise environmental monitoring. It uses a capacitive polymer‑film sensor to measure relative humidity and a temperature sensor covering a wide range.
Key features include a 4‑20 mA output proportional to 0‑100 % RH, a measurement accuracy of ±0.5 % RH, and a compact ABS housing weighing about 60 g. The device operates from a 24 V DC supply and consumes approximately 120 mW. This manual is written in Japanese.
