The Cole-Parmer Traceable 4155TR Thermohygrometer with Alarm (98768-48) is a calibrated environmental monitor with an integrated ambient sensor for simultaneous temperature and relative humidity measurement. It displays current, minimum and maximum readings and provides audible alerts when conditions move outside programmed limits.
Key Features
- Simultaneous temperature and humidity monitoring, using an integrated ambient sensor at the instrument location
- Wide environmental measurement ranges, covering 0 to 60 °C and 5 to 95% RH
- Reliable temperature measurements, with ±0.5 °C accuracy and 0.1° resolution
- Defined humidity accuracy, providing ±3% RH from 25 to 75% RH and ±5% RH outside this range
- Four independent alarm set points, supporting separate high and low limits for temperature and relative humidity
- Persistent audible alarm, continuing until acknowledged even when the measured condition returns within the programmed range
- Clear triple-line LCD, displaying current, minimum and maximum temperature or humidity readings
- Selectable temperature units, allowing readings to be viewed in °C or °F
- Individually numbered Traceable Certificate, supplied from an ISO/IEC 17025:2017 calibration laboratory accredited by A2LA
- Flexible bench or wall placement, with a bench stand and wall mount supplied
- Compact battery-powered design, operating from one included AAA battery
Benefits
- Identify temperature or humidity excursions promptly through configurable audible alarms.
- Review recent environmental extremes without continuous observation using the minimum and maximum memory.
- Support quality and compliance records with an individually numbered traceable calibration certificate.
- Monitor conditions during working hours, overnight and across weekends without permanent installation.
- Position the monitor where readings are required using either the supplied bench stand or wall mount.
- Read multiple environmental values quickly from the large triple-line display.
