The Extech 42280A is designed to continuously monitor temperature and humidity so you can maintain ideal storage conditions in laboratories and cleanrooms while ensuring comfort in hospitals and other indoor working facilities. This datalogger with max/min mode records up to 24,000 data sets including date and time stamp and features both audible and visible alarms. You can generate PDF reports that show trending graphs, or export data to a Microsoft Excel spreadsheet, making it easy to identify irregularities in temperamental environments.

The Extech 44550 is a pen style humidity and temperature meter. It features a dual LCD for simultaneous display of relative humidity and temperature (°C/°F switchable). This temperature pen measures humidity from 20% RH to 90% RH ± 5% RH and temperature from -10°C to 50°C ± 1°C (14°F to 122°F ± 2°F). It is pocket sized for quick and reliable measurements at any location. The max/min memory functions for display of highest and lowest readings for both measurements. Complete with pocket clip and one LR44 button battery.

Take this this handy humidity and temperature gauge on the go and rely on a long-lasting 3V lithium battery for maximum usage time. The slim Extech 445580 humidity/temperature pen will capture humidity readings from 10 to 90% RH and register temperatures from -10°C to 50°C (14°F to 122°F). This utility tool is ideal for field work, storing maximum and minimum readings until the memory is cleared and includes a data-hold button for rapidly fluctuating measurements. The meter comes complete with a pocket clip and 3V lithium battery.

The Extech 445702 combines 3 displays for time, temperature and humidity. The clock displays both 12 and 24 hour time. Includes a maximum/minimum with reset function. Humidity measures 10% RH to 85% RH ± 6% RH, and temperature measures -10°C to 60°C ± 1°C (14°F to 140°F ± 1.8°F). Complete with built-in tilt stand, wall mounting bracket, and AAA battery.
