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.

Questions & Answers

can I measure relative humidity inside an oven where the temperature could be up to 95C?

Asked by: Gani

Hi Gani, Thank you for the inquiry. The sensor is located at the top of the handheld and the max operating temperature range is limited to 50 C. Best regards OMEGA
