Chilled Mirror Hygrometer CR-4
Product Announcement from Buck Research Instruments, LLC
The CR-4 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.
