Dual Laser Infrared Thermometer for Industrial Measurement

The handheld OS758-LS dual infrared thermometer is a high-performance, non-contact temperature measurement instrument. It offers a broad array of features including color backlit LCD, adjustable emissivity, 60:1 distance to spot, maximum/minimum/average/diff temperature monitoring, hi/low temp alarm and data storage. This meter is also provided with a microSD card slot (SD card included).

The OS758-LS offers a sturdy design that is shatterproof at 1 m (3.3') with an ergonomic rubber boot handle. A Type K thermocouple input is provided for contact measurements and is frequently used to validate emissivity.
