The BCHP JX-3 Thermal Analyzer User Manual provides installation, operation, technical parameters, and troubleshooting for detecting benzene compounds and…
The JX-3 thermal analyzer, developed by Beijing Zhonghuipu Analysis Technology Institute, is designed for environmental air monitoring of benzene series compounds and total volatile organic compounds (TVOC). It integrates GB50325 detection methods and a six‑way valve sampling system to improve data repeatability.
This manual covers product overview, component list, installation steps, operation procedures, parameter settings, technical specifications, fault diagnosis, and after‑sales service information, guiding users from initial setup to routine maintenance. This manual is written in Chinese.
| Temperature control range | 50°C–380°C |
|---|---|
| Analysis pressure | 0–0.4 MPa |
| Calibration sample flow | 16–160 ml/min |
| Analysis / injection time | 1 s to 60 min |
| Sample tube specification | Diameter < Φ7 mm, Length > 120 mm |
| Operating voltage | 220 V ± 10 % 50–60 Hz |
Set the analysis pressure to the required value (e.g., 0.1 MPa) using the pressure adjustment knob on the instrument.
Verify that the power cable is firmly connected, the 4 A fuse is intact, and the internal circuitry is powered; replace the fuse if it is burnt.
Press the calibration (标定) button, then adjust the calibration flow rate as needed; the instrument will perform a purge and calibration cycle.
