The CHT series temperature and humidity transmitter is based on the HIH4000 heat-cured polyester capacitive humidity sensor and the HEL700 series PT1000 platinum resistance, after signal amplification processing and compensation, provide high-value OEM products for system integrators, temperature and humidity transmitter manufacturers and related equipment manufacturers.
The CHT series temperature‑humidity transmitters from Honeywell provide accurate humidity (0‑100% RH) and temperature (‑25 °C to +60 °C or ‑10 °C to +60 °C) measurement. They support 4‑20 mA two‑wire or 0‑5 V three‑wire output and are available for wall‑mount or PCB installation.
Typical applications include HVAC systems, telecom base stations, computer rooms, pharmaceutical facilities, museums and other environments requiring reliable environmental monitoring. The devices feature IP30 protection, robust ABS housing, and meet IEC electromagnetic compatibility standards. This manual is written in Chinese.
