The THT63 indoor temperature and humidity transmitter is specifically designed for accurate indoor temperature and humidity monitoring. It features a compact size, easy installation, and simple operation. Built‑in protections against lightning surges, static electricity, group pulses and high‑voltage interference deliver strong anti‑interference performance. It supports multiple output options, including current, voltage, and RS485 for flexible integration. The THT63 is ideal for computer rooms, commercial buildings, warehouses and other environments requiring precise temperature and humidity control.
