Cryogenic Hygrometer - CR-2 - from Buck Research Instruments L.L.C.
The CR-2 exhibits the same wide range, fast response and high reliability as the CR-1A, but it is smaller and lighter in weight. Mirror cooling is done by a closed cycle cryocooler rather than liquid nitrogen. Maintenance requirements are minimal. (read more)
The CR-4 from Buck Research Instruments, 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. Depending upon ambient temperature, it can measure dew points as high as 60°C. (read more)
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. (read more)
Buck Research Instruments' humidity conversion calculator App for the iPhonel allows conversions to/from dew point, relative humidity, mixing ratio, absolute humidity and vapor pressure, as well as calculating how these properties change when changing pressure and temperature. (read more)
