Categories: ,

Product Description

The Vaisala DRYCAP® Dewpoint Transmitter DMT152 is designed for measuring low dew point in OEM applications, even down to -80°C.

  • Compact and accurate
  • Vaisala DRYCAP® technology with a polymer sensor
  • Measures dew point down to -80°C (-112 °F)
  • Reduced maintenance costs due to long calibration interval
  • Fast response time
  • Withstands condensation
  • NIST traceable
  • Compatible with the Vaisala MI70 indicator
  • Optional loop powered display, Nokeval 301

Low Maintenance The DMT152 mechanics have been designed for harsh environments requiring protection against dust, dirt, and splashed water. The DRYCAP® technology has a low maintenance need due to its excellent long-term stability and durability against condensation.

Applications The DMT152 is an ideal choice for industrial applications where it is necessary to control very low humidity. Most typical areas of use are air and plastics dryers, dry chambers, pure gases, and highvoltage circuit breakers. The DMT152 measures accurately and reliably also in the challenging combination of low humidity and hot air, which is typical in plastics drying.
