Vaisala DMT132 Dewpoint Meter

Vaisala DMT132 Dewpoint Transmitter is a low cost, dew point instrument.  Specifically designed with refrigerant dryer applications in mind, the Vaisala DMT132 uses patented HUMICAP sensor technology. This ensures long-term stability and repeatability.  The HUMICAP sensor is also resistant to compressor oil.

For extremely dry applications, consider the Vaisala DMT152 Compact Dewpoint Transmitter with a measurement range as low as -80°C Td.
