Description

Overview

GAOTek nitrogen gas detector adopts a 2.31-inch high-definition color screen for real-time display and adopts gas sensors of well-known brands in the industry. It is used to quickly detect the concentration of various gases and the measurement of ambient temperature and humidity, and alarm if the measurement exceeds the limit. It is suitable for detecting gas concentration in pipelines or confined spaces and atmospheric environments; gas leakage or high concentration single gas purity where various background gases are nitrogen or oxygen. There are more than 500 kinds of detected gases.

 

Features

  • It can detect 1 to 4 kinds of gases at the same time, and the unit can be switched: Optional units: PPM, mg/m3, VOL %, LEL %, PPHM, ppb, mg/L
  • Built-in pumping measurement, integrated water vapor and dust filter, quick response and support long-distance sampling
  • Rich man-machine interface. The 2.31 inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity and storage, communication
  • Large-capacity data storage function, support multiple storage methods
  • High temperature gas detection (optional)
  • Three display modes can be switched
  • Graphic display. Reflect the trend of gas concentration changes over a period of time in the form of a curve
