Vaisala DM70 DRYCAP Dew Point and Temp Meter
Take in-line measurements with a handheld meter
Handheld meter withstands condensation for use in pressurized spaces
Drycap® sensor technology provides accuracy, reliability, long-term stability, and fast response
Meter logs all readings for later analysis—simply download to your PC via the RS-232 interface
Dewpoint meter is ideal for use in industrial spot checking of compressed air lines, plastic molding processes, and other dry gas applications. Meter accurately measures dew point temperature from –40 to 140°F (–40 to 60°C). Sensing probe features the unique Drycap polymer-based technology that enables reliable dewpoint measurement.
The easy-to-connect sample cell adapter withstands condensation and is easily connected allowing it to be placed directly in pressurized spaces. Readings are displayed either numerically or graphically on the backlit LCD—simply press a key and the display changes to a real-time graphic display. Meter has a unique auto-calibration feature that extends the calibration interval and provides long-term stability.
What’s included: Windows®-based analysis software, analog output signal cable, sample cell adapter, certificate of NIST traceability, rechargeable battery pack, 115 VAC adapter, and carrying case.
