United Scientific Supplies UNHT-3PK8 Relative Humidity and Temperature Sensor Wand Laboratory Grade Environmental Monitoring Probe, Pack of 8 pcs

This compact device fits into small places to monitor the relative humidity and temperature. If using in an environment with a heatsource, do not place the probe directly near it. The easy-to-read digital LCD display shows the temperature to one decimal. The larger display shows the relative humidity of the air.
To ensure proper monitoring, make sure the device is positioned so it is exposed to air on the front and back. Allow a few minutesfor the sensors to catch up to the environment before recording areading.
