Control Company Digital Thermohygrometer

Continuously and simultaneously displays relative humidity and temperature in °F/°C with dual-recall memories. Place the sensor in hoods, clean rooms, coolers, stockrooms, incubators, environmental chambers, desiccators, and chemical storage areas. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). ABS Plastic housing is chemical- and shock-resistant. Supplied with a wall mount and bench stand, switch to read °F/°C, fast-response, solid-state sensors, and two AAA batteries. Digital hygrometers don't provide quite as much accuracy as hair-hygrometers, but they don't ever need to be calibrated.

Traceable® Min/Max Alarm Relative Humidity/Temperature Monitor, 32.0 to 140.0°F / 0.00 to 60.0°C Temperature Range and 5 to 99% Humidity Range. Includes a NIST Traceable® Calibration Certificate (each)

Minimum and maximum memory
Triple display simultaneously shows minimum/maximum and current humidity, or minimum/maximum and current temperature. Minimum and maximum memory feature for both temperature and humidity permits monitoring conditions overnight, on weekends, or any time period. External sensor on 7 foot cable reads temperature and humidity. Humidity range is 5 to 99% with a resolution of 1%. Accuracy is ±3% RH midrange. Temperature range is from 32.0 to 140.0°F / 0.00 to 60.0°C. Resolution is 0.1°. Accuracy is ±0.5°C.

High and low alarm
Alarm may be set in 1% RH and 1° increments. Alarm sounds when reading rises above or falls below set points. Unit is supplied with a flip-open stand for lab bench and slot for wall mounting. Easy-view, 1/2-inch-high digits may be read from 10-feet. Supplied with one AAA battery for continuous, 1-year always-on monitoring and external humidity/temperature sensor. Case is high-impact, chemical-resistant ABS plastic. Unit measures 4-1/4 x 2-3/4 x 3/4 inches and weight is 4 ounces. Replacement battery Cat. No. 1105.
