Description
Overview
GAOTek high precision portable oxygen gas analyzer with inner pump swiftly and accurately measures gas concentration, temperature, and humidity on-site, triggering alarms for exceedances. Featuring a 2.5-inch HD color screen, it employs top-tier sensors (electrochemical, infrared, catalytic combustion, thermal conductivity, PID ion), Swiss capacitive digital temperature and humidity sensor, advanced circuit design, and patented algorithms. Suitable for pipelines, confined spaces, and atmospheric environments, it detects 500 + gases and assesses purity in high concentration single gases against diverse backgrounds like nitrogen or oxygen.
