Description

The 381A Combination Non-Contact & Contact Thermometer is a non-contact and contact temperature tester with laser sighting to confirm your target. It uses K-type thermocouples with sub-mini connector for contact measurements. The Combination infrared digital thermometer can easily switch between detection modes for greater accuracy and flexibility in different applications and scenarios. With laser guidance to assist in hard-to-reach areas.

1. What does “distance to spot ratio” mean?

    The laser spot needs to be showing inside the target area. An 8:1 “distance to spot ratio” means you are measuring a 1” diameter area at a distance of 8”.

2. How far can I measure?

    Distance is unlimited. The size of the target area sets the limit on distance for accurate measurements. Example: If the area you wish to measure is 1 foot in diameter, then you will need to be within 8 feet to record an accurate temperature.

3. What is the smallest target I can read?

    Approximately one-half inch in diameter.

4. What is emmisivity?

    This is a ratio of an object’s infrared emission compared to a theoretical black body considered 1. Emissivity is always less than 1. Adjustable emissivity allows your non-contact thermometer to be adjusted to the surface you are checking to make readings more accurate.
