- Microprocessor-based design provides unparalleled accuracy
- Simultaneously displays both temperature and relative humidity on dual 1.125" high LCD
- 3 foot cable allows user to retrieve readings from hard-to-reach areas
Maintain accuracy with do-it-yourself calibration. Traceable® Memory Hygrometer/Thermometer measures from 10.0 to 95.0% relative humidity and temperature from 0.0 to 199.9°F and –18.0 to 93.0°C. Precision thermistor offers a temperature accuracy of ±1°C between 0 to 40°C, otherwise ±2°C, and a resolution of 0.1°. Reads Fahrenheit and Celsius. An audible click confirms each key entry. See listing for dew point model specifications.
Resistive polymer film sensor provides humidity readings with an accuracy of ±2% mid-range to ±4% elsewhere. Humidity resolution is 0.1% relative humidity. At the touch of a button, recalls the minimum and maximum humidity and temperature readings captured during any time period. A special HOLD button permits freezing the display to capture readings. Features an auto-off battery saving function which may be deactivated.
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.
Unit is equipped with an output receptacle for transferring data to a computer. Use to monitor conditions in clean rooms, computer rooms, storage facilities—virtually anywhere temperature and RH affect vital components and tests. Handsome, dual-tone ABS plastic case is both lightweight (10-3/4 ounces) and rugged for extreme field or lab use. Supplied with probe/cable, Traceable® Certificate, hard plastic carrying case, and 9-volt battery for 100 hours of continuous use. Size is 7-1/8 x 2-3/4 x 1-1/4 inches. Probe is 8-1/2 inches long with 2/3-inch diameter with a 3-foot cable. Replacement battery Cat. No. 291-1112.
