New CR-1A Cryogenic Hygrometer

A ±0.1% accuracy pressure transducer is included for measuring mixing ratio (ppmv or lbs/MMSCF). There is an optional 4.5 Ah battery pack, and an optional autofill system for continuous use applications.

The CR-1A is designed to operate with virtually no attention. Maintenance demands are minimal, consisting of dewar filling and occasional mirror cleaning as necessary.

NEW CR-2 Aircraft Hygrometer

The CR-2 exhibits the same wide range, fast response and high reliability as the CR-1A, but it is designed specifically for aircraft and similar high-stress applications. Instead of using Liquid Nitrogen (LN2), mirror cooling is accomplished using a tactical cryocooler, which is a high-tech device used primarily to cool IR detectors in missiles and tank turrets to LN2 temperatures.

Maintenance requirements for the CR-2 are minimal. Aside from occasional mirror cleaning, the cryocooler needs to be renewed every 10,000 hours of use. Both the control circuitry and the sensing assembly are mounted together into a single compact unit. A separate display module is provided that displays the dew / frost point and housekeeping signals. (For aircraft operat...
