AI-RHTm-E LCD Digital Temperature Humidity Monitor is a reliable instrument for accurate temperature and relative humidity measurement using an external wired sensor. This Temperature Humidity Monitor features a high-brightness LCD display with HI and LO limit indications for clear monitoring. The RS485 Temperature Humidity Monitor supports Modbus communication for integration with PLC, BMS, and SCADA systems. Its alarm buzzer, front-panel ACK, and flexible sensor placement make it a practical solution for continuous Cleanroom Monitoring System requirements.
Applications: Pharmaceutical cleanrooms · Hospital operation theatres · Isolation rooms · Medical and pharma laboratories · Greenhouses · Controlled storage areas
The Ace AI-RHTm-E LCD Digital Temperature Humidity Monitor (External Sensor) is supplied as a two-part system: a wired external temperature and humidity sensor and a separate flush-mount display unit, connected by cable. Separating sensor from display allows each to be positioned independently. This suits installations where wall construction, cable routing or panel space constrain display placement, and applications where the measurement point and the reading point are not the same location.
