Traceable* Humidity and Temperature Hygrometers with Analog Recorder Output

Digital readout permits instant readings of relative humidity and temperature °F/°C. Output jack provides a 10 millivolt signal per degree or per 1% RH. Use with a chart recorder, strip recorder, or computer that accepts millivolt signals. Ideal to monitor conditions in chambers, clean rooms, food processing, scientific labs, and all humidity-sensitive manufacturing operations. Recorder output provides a hard copy record.
Supplied with a certificate traceable to NIST (National Institute of Standards and Technology). Humidity range is 10.0 to 95.0% RH and temperature range is -4.0 to 140.0°F (-20.0 to 60.0°C). Resolution is 0.1° for both readings. Accuracy is ± 2.5% RH and 0.8°C. Response time is approximately 3 minutes. Data hold switch freezes the display to capture a reading.
The large, bright, 1/2 in. high, four-digit, liquid crystal display can be read from 10 feet away. The rugged, handheld unit is completely portable and designed for years of dependable and reliable service.
Replaceable 9-volt battery powers the unit for 1 year of intermittent use or 100 hours of continuous readings. Precision thin-film capacitance sensor updates the display two and a half times per second. Supplied complete with Traceable Certificate, 9-volt alkaline battery, and carrying case. Size is 2 1/2 x 10 1/2 x 1 inches and weight is 7 ounces.
