High performance humidity handheld meters available with USB or wireless connectivity. They offer a double display to show the temperature and humidity from built in sensors and can alternately display data from a separate Type K thermocouple connected via SMP type miniature connector. Save function allows storage of up to 256 readings (no time-stamp) to internal non-volatile memory. Software for USB and wireless versions is included to allow internal, external temperature, and RH data to be recorded by a PC. Interface cable is included with the USB version; receiver with the wireless version.

Rated 1 out of 5 by Anonymous from Purchasing Agent We got sent ones that the cert for calibration was expired already.

Rated 4 out of 5 by MME Forensic from Mostly good, one disapppointment I like all the features and know that I'll likely get a lot of use out of it. The disappointment is the first time I used it and saved 240 data points 80% of the file was corrupted when I downloaded to Excel. Only the first 48 data points were good. The rest were trash. Maybe I did something wrong, so I'll keep trying.
