FAS-W Online Moisture & Dew Point Analyzer

Automatic chilled mirror: dew point measured directly, moisture calculated.

An automatic chilled-mirror analyzer that measures water dew point directly and calculates moisture concentration from the measured pressure. Available as version A (dew point), B (moisture concentration) or C (both).

ACTS is Blue Dragon Technology’s sole agent in Egypt, supplying the FAS-W Online Moisture & Dew Point Analyzer to oil & gas, petrochemical and power generation plants nationwide from our office in Sheikh Zayed City, Giza. Sizing and selection are handled by our own application engineers, with aftermarket support and technical services once the unit is in service.

Key Features
  • Chilled-mirror measurement, not an inferred sensor reading
  • Integrated absolute pressure sensor
  • RS-485 Modbus RTU with 500 V isolation
  • Active 4–20 mA and two dry-collector alarms
Engineering Benefits
A directly measured dew point is the reference other hygrometers are checked against
