About This Product
Having both sensors lets students compare the surface temperature of a beaker, block or food sample with the temperature at its centre, which shows how heat moves through a material. The infrared mode is also handy for hot plates and other objects that should not be touched.
Frequently Asked Questions
What is the distance-to-spot ratio of this infrared thermometer?
It is 2:1, suited to measuring targets close by on a laboratory bench.
Can the emissivity be changed?
No. Emissivity is fixed at 0.95, a value used for organic and matte surfaces.
