Rated 2 out of 5 by from Don‘t know how to use This item is too new to find a specific mannul for it. I have asked the mannul two times and that was the answer of that. It has two last points, however, the two laser point could not combine to one spot which mease I could not make sure which point exactly it is testing. So I return it back.

Does the OS758 come with a calibration cert ? If so, is that good for 1 year ?

Asked by: Jef64
Thank you for your inquiry Jef64. The OS758 does not come with a calibration certificate. Calibration can last up to one year depending on the use of the IR sensor. It's recommended to calibrate sensors every year. You can request calibration for this sensor during purchase.

I was looking for on online manual, but did not see one. I see that it comes with a connector to plug a probe sensor that can be used for emissivity verification. If I wanted to do that, how would I install the wires for the probe port?

Asked by: JBien
Thank you for your interest in our product. The manual for the OS758-LS is per the attached link The OS758-LS has a receptacle that accepts a type K mini flat prong connector .One type K thermocouple with connector comes with unit. We also offer many different type K probe styles with a connector that can be used with the OS758-LS . Probe selection is based on temperature range min and max , and application. For probe selection assistance please email details of your application to
