42525A provides non-contact (IR) and contact (type K) temperature measurement capability. The built-in laser pointer (activated by pressing the meter’s trigger) increases target accuracy. The Model 42525A has an RS-232 PC Interface jack for recording readings as they are taken. Professional features include EMISSIVITY ADJUST, RELATIVE MODE, DATA HOLD, DISPLAY OFFSET, and MIN MAX DISPLAY. -

Page 5: Distance To Object
Distance to Object Infrared Measurement Considerations 1. The 42525A automatically compensates for ambient temperature deviations; however it may take up to 30 minutes to adjust to extremely wide ambient temperature changes. 2. When low temperature measurements are taken followed by high temperature measurements, several minutes are required for stabilization before the high temperature measurements can be made accurately. - Page 6 Emissivity values range from 0.1 for a very reflective object to 1.00 for a flat black finish. The Model 42525A uses a factory default emissivity setting of 0.95 (this setting covers most applications).
- Page 7 Laser Pointer Operation This 42525A is equipped with a laser pointer that is used to aim the IR sensor more accurately. Simply press the meter trigger to activate the laser pointer. Be extremely cautious when directing the laser beam, shining the laser beam into someone's eye can cause serious injury.
