FLIR's MR77 is a pin and pinless moisture meter and also includes a built-in IR thermometer!

Rugged, feature-packed and suitable for use in any moisture application, the MR77 can be used to carry out completely non-destructive measurements using the pinless moisture sensor or alternatively can use its wired pin probe to carry out invasive measurements below the surface of a material. The wired measurement mode has a external pin probe on a 30" wire, making it easier to reach difficult applications that other moisture meters wouldn't be suitable for.

The FLIR MR77 has an integrated, field-replaceable temperature and humidity sensor included as well for evaluating the status of the air in the environment around the tester. Alternatively you can use the built-in infrared (IR) thermometer to measure surface temperature without the need to make direct contact.

All these values can be shown directly on the MR77's built-in, large-size LCD screen. It's also possible to transmit this data wirelessly to compatible smartphones and tablets (Android only) and can interface wirelessly with FLIR thermal cameras using METERLiNK technology.
