PRODUCT OVERVIEW

Introduction to Vaisala DRYCAP

Hand-Held

Dewpoint Meter DM70

DM70 measures dewpoint temperature accurately in a measurement

range from -60 °C up to +60 °C depending on the probe version.

DM70 incorporates the advanced DRYCAP

technology, which

enables reliable and high-performance dewpoint measurement. DM70

measures the following quantities:

- dewpoint/frost point

temperature T

d/f

(°C/°F)

- dewpoint temperature

(°C/°F)

- temperature T (°C/°F)

- dewpoint/frost point in the atmospheric pressure T

d/f

(°C atm/°F atm)

- dewpoint in the atmospheric pressure T

(°C atm/°F atm)

- relative humidity RH (%)

- humid air /dry air H

O ppm

/ppm

- absolute humidity a (g/m

)

- mixing ratio x (g/kg)

d/f

shows the dewpoint temperature above the freezing point (0

°C/32 °F) and frost point temperature T

(dewpoint over ice) below the

freezing point. This is considered as the industry standard.

shows the dewpoint over water throughout the entire

measurement range.
