Description

Overview

GAOTek HF gas detector is ideal instrument when it is necessary to test water content, purity and decomposition products of SF6 gas. The core component of dew point test is DRYCAP series sensors produced by Finland Vaisala company. With professional hardware chips and excellent software algorithms of STMicroelectronics, a new generation of gas moisture test instrument.

 

Features

  • Full-channel polymer material design
  • Provides both standard dew point values
  • Provides converted dew point values at 20 °C
  • Purity measurement
  • 5 % measurement accuracy of full scale
  • Used for high concentration SF6 gas measurement
  • 70 % SF6 gas measurement
  • The best test flow area display
  • The user adjusts gas flow intuitively and quickly
  • Reduce test time
  • Air inlet designed with miniature self-sealing joint
  • Tested air path will not leak
