QRD QRD1112C Thermal Conductivity Hydrogen Sensor User Manual
The QRD1112C thermal‑conductivity hydrogen sensor is used to measure hydrogen percentage in gas streams and to calculate ammonia decomposition rates in heat‑treatment furnaces. It operates within a temperature range of 5‑50 °C and requires a dry, low‑dust gas flow of 0.5 L/min.
The document provides technical data such as a 0‑100 % H2 measurement range, 0‑100 mV output, and a supply voltage of 220 V ±10 %. It also details the electrical system, mounting method (four Φ5 screws), and step‑by‑step procedures for startup, zero‑point, and full‑scale calibration. This manual is written in Chinese.
