The MBW CALIBRATION™ MODEL 473-SH2™ Dew Point Chilled Mirror Analyzer with a cable mounted measuring head with an integrated sample flow control fan delivers fast, high precision temperature measurement. It is ideal for use in climatic chambers or humidity generators where it functions as a calibration transfer standard for dew/frost point, relative humidity, and temperature. The 473-SH2 includes precise measurement of temperature with a 2 x 100 mm platinum resistance thermometer (PRT) that can be connected directly to the SH2 measuring head, or to the MODEL 473 display.
The SH2 is a flow-through dew point measuring head with a two-stage Peltier element for mirror temperature control. It includes a variable speed fan that maintains a consistent airflow across the mirror. Alternatively, with the fan removed, the SH2 head can also connect to applications using tubing and standard 6 mm or ¼” fittings. It is also supplied with a calibrated temperature probe with 0.5 m and 3 m cables for connection to either the measuring head or the 473 back panel.
