Description

The OM-140 Series are low-cost, compact, battery powered temperature and humidity data loggers, capable of unattended logging (recording) of the ambient temperature and relative humidity (RH) of an environment for days, weeks or months. The OM-144 data logger can also measure and optionally log surface temperatures spot-checked by a technician using the unit’s integral infrared (IR) thermometer.

These loggers can also calculate and display absolute humidity levels in units of grams per kilogram (GPK) or grains per pound (GPP). Also called mixing ratio, GPK is a more useful moisture metric than RH to water damage restorers. Using RH alone, a restorer might unknowingly introduce moist air - with a low RH but a high GPK - during a job's drying phase.

Data logging can be started or stopped by pushing a button on the logger, eliminating the need to bring a laptop to the job site. After a data log has been captured and stored, it can be uploaded as a .txt file to any PC running the Windows® XP/7 or 8 operating system after plugging the data logger into one of the computer's USB ports. The data logger's internal flash memory is large enough to store 16,300 pairs of temperature and RH readings or for the model OM-144 nearly 10,000 sets of RH, ambient temperature and surface temperature readings. Included with the product is a mini-disc with the drivers needed to interface the unit to the computer, as well as software that can display a data log file as a table or graph and/or export it to Microsoft Excel. Exporting to Excel is recommended for sophisticated trending and analysis of humidity and temperature data and easy detection of unexpected excursions.
