Infrared Thermometers

Introduction

The 561, 566 and 568 Infrared Thermometers ("the thermometers" or "the
Product") are for non-contact temperature measurement. These thermometers
determine an object's surface temperature by measuring the amount of infrared
energy radiated by the object's surface. The thermometers also support contact-
temperature measurement via K-type thermocouple.
Note that the Japanese models indicate Celsius only.
