Gas analyzer version is commercial, housing protection against dust and water is I54.

ANKAT-7655-01 consists of power-indication unit and sampling unit, connected with each other by cable of up to 50 m. Sampling unit includes sensor, pressure stabilizer for analyzed water.

Analyzer provides:

  • digital indication of oxygen concentration with less significant digit 1 μg/dm3
  • sensitivity calibration
  • signaling on sample temperature increase, damages (sensor unit depressurization), absence of sensor signal
  • no gas mixture calibration
  • Calibration interval is 1 year

Delivery set:

  • Gas analyzer
  • SPTA set
  • SPTA set list
  • service papers
