Perfect for hoods, storerooms, cleanrooms and other environments that need to be monitored

Traceable® Excursion-Trac™ Datalogging Humidity/Thermometer

The perfect unit for hoods, storerooms, cleanrooms, incubators, drying and environmental chambers

  • Rolling memory structure, maintains 525,504 humidity and temperature observations
  • Smart-Alarm™ features a visual/audible alarm that continues to alarm even if the unit returns to non-alarm conditions
  • Stores up to 30 unique alarm events
  • Memory can be cleared on unit after downloading data to USB stick
  • Hassle-free retrieval of data - unit can remain in use while downloading and analyzing data
  • Status indicators - Low battery, memory full, USB data transfer and active alarm state


Hi/Lo Alarms and Time/Date Stamps

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.

Smart-Alarm™ signals out-of-range conditions

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.

Excursion-Trac™ Features

Monitor readings overnight, on weekends, or for any time period with rolling data log. User-defined datalogging interval of 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.

Measuring Ranges

High-accuracy ambient and external probe relative humidity range: 0 to 95%RH, non-condensing and resolution of 0.1% and maintains an accuracy of ±3% RH between 5 to 75%, otherwise ±5% RH. Ambient temperature range: 32 to 145°F (0 to 65°C) and external probe temperature range: –4.0 to 158.0°F (–20.0 to 70.0°C) and resolution of 0.1° and maintains an accuracy of ±0.4°C across entire temperature range for both ambient and external probe.

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. 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, hook and loop tape, magnetic backing, wall mount, Traceable® Certificate, and batteries. Replacement battery Cat. No. 1105.
