Description:
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. Memory captures 99 data points which can be recalled on command. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by 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 mid-range to ±5% RH elsewhere. Response time is 30 seconds to 5 minutes. 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. 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.
