Quick-Export Temperature and Humidity Data Recorders
No cords or software required—these data recorders store readings on an included SD card in Excel format for easy transfer to a PC.
Data recorders with a NIST certificate of calibration include a calibration certificate traceable to NIST that states the recorder has passed a test for accuracy.

Charts for Temperature and Humidity Chart Recorders
Remote-Reading Temperature, Humidity, and
Dew Point Chart Recorders with High/Low Alarm
Remotely record temperature, humidity, and dew point up to 10 feet from the display and set the alarm to sound and flash the display if temperature readings rise above or fall below a set range. This recorder has a remote probe on a 10-ft. cable and a display that can be set to show current temperature, minimum/maximum temperature, or relative humidity and calculated dew point. Charts (not included) are required; select a recording time and temperature range from the available chart options.

Temperature and Humidity Chart Recorders with Calibration Certificate
Track ambient temperature and humidity over time with this recorder that includes a calibration certificate traceable to NIST that states it has passed a test for accuracy. Recorders come with a replaceable sensor, so no probe is needed. Charts (not included) are required; select a recording time and temperature range from the available chart options.

Through-Wall Humidity and Temperature Meters
Monitor relative humidity, temperature, and dew point inside sealed containers. These meters are rated IP67, so they won't expose contents to dust and water. The housing is aluminum, which is lightweight and resists corrosion.

Humidity-Indicating Plugs
Monitor humidity in sealed containers without opening them, protecting the inside from contamination. These plugs are often used on plastic bags, storage containers, and electrical housings. Consisting of a mounting nut and two gaskets for a tight seal, these plugs install through a hole in a flexible barrier. Remove one gasket and reverse the nut to install plugs in a rigid container. Watch the indicator disc through the nut’s viewing window—it will change color as humidity rises and falls. Made of anodized aluminum, these plugs resist corrosion and are lightweight. They meet military and SAE standards for humidity indicators.

Humidity-Indicating Cards
Check humidity levels of moisture-sensitive inventory and equipment at a glance. To detect moisture exposure when packaging, shipping, and storing electronics and chemicals, these cards have dots that change color as humidity levels change. Store electronics in a moisture barrier bag with one of these cards and a desiccant bag (bags not included). To revert these cards to their original color, place them in a dry container for 24 hours or bake at 180° F for 3 hours. Cards will not revert to their original color once they reach 60% or greater humidity. They meet industry guidelines for packaging moisture-sensitive devices.
