Eddie Technology Dual-Range Optical Interference Methane Detector Calibration Device

Product Introduction
The dual-range optical interference methane detector verification device is primarily used for the verification and calibration of mining optical interference methane detectors. It complies with the JJG677-2006 "Optical Interference Methane Detector" verification regulation and the MT28-2005 "Optical Interference Methane Detector" standard requirements. It is an ideal product for metrology inspection institutions or major mining bureaus and coal mines to perform periodic calibration/verification of mining optical interference methane detectors.
Performance Features of the JZG-IV Dual-Range Optical Interference Methane Detector Verification Device:
1) Achieves fully automatic pressure pressurization; automatic pressure compensation during testing.
2) Simultaneously displays pressure, temperature, humidity, and methane concentration.
3) Equipped with verification software, enabling automatic data collection, with software completing calculations and result determination.
4) Independently stores test data, supports fuzzy queries, and enables automatic printing of original records and double-sided reports.
5) For measurement accuracy, pressure uses imported transmitters, temperature uses imported transmitters, offering high precision and stability. Multi-functional, the temperature sensor and pressure transmitter can serve as standard devices for calibrating temperature sensors and pressure sensors after verification.
