Traceable® Remote Sensor RH/Temperature Monitoring Digital Hygrometer with Alarm is ideal for routine measurements, monitoring round-the-clock, all quality-control needs, and critical experimental requirements. 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. 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. Replacement battery available (Cat. No. 350-19942). 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.
