This product is a wall-mounted thermo-hygro transmitter that uses a large-screen LCD display, a standard 4mA-20mA current signal output, linear response, temperature and humidity integration, a dedicated circuit, a wide measurement range, high accuracy, and stable performance.
This manual describes the BR-2000HTB/D temperature and humidity transmitter, including its physical dimensions, mounting methods, and main performance specifications such as temperature range 0‑50 °C and humidity range 0‑99.9 %RH. It also details the 4‑20 mA signal output, power supply requirements (12‑24 V DC), and connection details.
Installation notes advise aligning the device correctly, avoiding direct exposure to strong light or heat sources, and maintaining a minimum 20 cm clearance when mounting on surfaces with large temperature differences. Regular maintenance after 12 months is recommended to ensure reliable operation. This manual is written in Chinese.
