Digital display permits instant readings of relative humidity and temperature (°F/°C). It is ideal to monitor conditions in chambers, clean rooms, food processing, scientific labs, and all humidity-sensitive manufacturing operations.
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 mid-range to ±5% RH elsewhere. Data HOLD switch freezes the display to capture a reading. Large, bright, 1/2-inch-high, four-digit liquid crystal display can be read from 10 feet away. Rugged handheld unit is completely portable and designed for years of dependable and reliable service.
Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from an ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.
Battery powers the unit for 1 year of intermittent use or 100 hours of continuous readings. Precision thin-film capacitance sensor updates the display three times per second. Supplied complete with Traceable® Certificate, 9-volt alkaline battery, tripod mounting hole, and hard carrying case. Size is 2-1/2 x 10-1/2 x 1 inches. Weight is 7 ounces. Replacement battery Cat. No. 291-1112.
