Traceable® External Probe RH/Temperature Monitoring Hygrometer

TRACEABLE^® CERTIFICATE

Multi-point calibration on an individually-numbered Traceable^® Certificate which assures accuracy from our ISO/IEC 17025:2017 (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.

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. Internal Ambient sensor reads temperature and humidity. Humidity range is 5.0 to 95.0% with a resolution of 0.1%. Accuracy is±3% RH from 25-75%,±5% otherwise. Temperature range is from 32.0 to 140.0°F and 0.0 to 60.0°C. Resolution is 0.1°. Accuracy is ±0.5°C.
