The OS3750A Series is a small, lightweight handheld thermometer with a clear viewfinder. The thru-the-lens optical system enables it to measure small targets from a long distance. The measured value can be read on the internal digital display in the viewfinder. Three models are available.

The OS3753A IR Pyrometer combines the functions of a 2-color and single color wide range pyrometer in one model. The OS3751A is a single-color medium temperature range model, and the OS3752A is a single-color high temperature range model.

The OS3750A Series can be mounted on a tripod or when there is no room for a tripod, on a fixed location by a universal head (sold separately).

OS3750A-SOFT Datalogging Software Data logging software is available for easy data processing by a personal computer. Three kinds of data management modes are available: real-time trend mode, multi-point monitoring mode by utilizing memory, and 1-point historical trend mode. Graph display, report creation, printing, and data storage can be easily executed. The export of the measured data to worksheet applications is also possible.

Caution: This product and all in the series are not for use in medical evaluations. These products cannot be used to measure body temperature. They are meant for industrial and scientific purposes.
