AJ590 Portable harmful gas leak detector

1、 Overview

Pump suction gas tester is used for rapid detection of various gas concentrations and gas leakage measurements. If the measured value exceeds the alarm threshold, it will emit an audible and visual vibration alarm. Using a 2.6-inch high-definition color screen for real-time display and utilizing gas sensors from well-known industry brands for high-precision gas measurement. The main detection principles include: electrochemistry, infrared spectroscopy, catalytic combustion, thermal conductivity, PID photoionization, etc. Advanced circuit anti-interference design, mature kernel algorithm processing, beautiful appearance design, have obtained multiple software copyrights and appearance design patents. Suitable for detecting gas concentration in pipelines, confined spaces, and atmospheric environments; Detect gas leaks or high concentration single gas purity with various background gases such as nitrogen or oxygen. There are over 500 types of gases for detection.
