CR-5 HYGROMETER-Image

The CR-5 is a chilled mirror hygrometer that uses a 3-stage thermoelectric cooler (TEC) to enable frost point measurements of as low as ­60 °C, under favorable ambient conditions. It is configured as a transmitter module with an external sensor connected by cable up to 9 feet in length.

Depending upon ambient temperature, the CR-5 can measure dew points as high as 60 °C and can display moisture concentration (ppmv or lbs/MMscf) with optional pressure sensor or %RH with optional ambient temperature sensor. Both of these require the optional LCD display The CR-4 is designed to measure in air and most non-corrosive gases at pressures ranging from near vacuum to up to 100 psia.
