225-4465CF Humidity/Temperature Meter

The Model 225-4465CF Humidity/Temperature Meter is a relative humidity meter combined with a C/F switchable thermometer in a rugged case for use in a variety of locations and applications including offices, factories, clean rooms, greenhouses, fire and flood restorations, etc.

A thin-film capacitance sensor provides accurate humidity measurements to ± 3% over a 10-95% range with a 0.1% RH resolution. A semiconductor sensor is used for temperature measurements of ‑4deg; to 140°F and ‑20° to 60°C with an accuracy of ± 1.5°F (±0.8°C). Response is less than three minutes for a humidity rise of 50%.

The unit features a built-in analog output jack. The output signal is 10mV/1% RH, 1°F, or 1°C and is suitable for use with a chart recorder. A large 3.5 digit LCD display indicates function and low battery. A data hold feature holds the displayed value until released. The instrument comes complete with carrying case and 9V battery. Battery life is approximately 400 hours.
