Weber Scientific Traceable Excursion-Trac Datalogging Humidity/Thermometer

The Traceable Excursion-Trac Datalogging Humidity/Thermometer is the perfect unit for hoods, storerooms, cleanrooms, incubators, drying and environmental chambers. It measures relative humidity range of 0 to 95%, non-condensing with a resolution of 0.1% and maintains an accuracy of ±3% RH between 5 to 75%, otherwise ±5% RH. The ambient temperature range is 32 to 145°F (0 to 65°C) and external probe temperature range of -4.0 to 158.0°F (-20.0 to 70.0°C) with a resolution of 0.1° and maintains an accuracy of ±0.4°C across the entire temperature range for both ambient and external probes.

The HI/LO alarms can be set for relative humidity and temperature. Alarm tracking feature stores in memory each alarm event detailing when the alarm state occurred, as well as when the unit returned back to within range. Alarm state indicators include audio alerts and flashing LCD segments. Data for up to 30 different alarm events can be retrieved with the most current event viewable on display. When an out-of-range condition is sensed, the Smart-Alarm™ triggers. Smart-Alarm features visual and audible indicators which signal continuously until acknowledged, even if conditions return to non-alarm range.

The Excursion-Trac allows you to monitor readings overnight, on weekends, or for any time period with rolling data log. User-defined datalogging interval allows one observation/minute to one observation/12 hours. Memory capacity maintains 2 years of recorded data when using 2 minute intervals and longer when using larger intervals. No software is needed for computer interface. Each device has a unique ID allowing multiple units to be used in the same location. This device provides recorded data in a CSV format that can be transferred from the hygrometer to any computer with use of a USB flash drive. No specific software is needed for the device and data can be deleted from memory.

Each unit is supplied with a multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from an ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited with 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. High-impact, chemical-resistant ABS plastic case is 5-1/2 x 3-1/4 x 1 inches. Weight is 6 ounces.

Supplied: probe, stand, Velcro®, magnetic backing, wall mount, Traceable® Certificate, and batteries
