Indoor Temperature & Humidity Transmitter | 4–20 mA, 0–10 V & RS485

This indoor temperature and relative humidity transmitter is designed for reliable environmental monitoring in offices, plant rooms, laboratories, and commercial buildings. The compact, wall-mount enclosure promotes good airflow for fast response and accurate readings, while internal temperature compensation and linearisation ensure long-term stability.

High-precision sensing elements measure temperature and humidity across a wide range of indoor conditions. With selectable outputs—4–20 mA, 0–5 V, 0–10 V, and RS485—the transmitter integrates easily with BMS, PLCs, RTUs, SCADA systems, and data loggers.

The device is engineered for continuous operation in demanding indoor environments and supports compliance-driven monitoring programs where accuracy and repeatability are essential.
