Non-contact infrared thermometer

            Instruction manual

Introduction 
    Compact, rugged and easy to use. Just aim 
    and push the button, read current surface 
    temperature in less than a second. Safely 
    measure surface temperature of hot, 
    hazardous or hard-to-reach objects without 
    contact.

Cautions
    Infrared thermometer should be protected 
    from the following: 
    --EMF (electro-magnetic fields) from  
    welders, induction heaters.
    --Thermal shock (cause by large or abrupt 
    ambient temperature changes allow 30
     minutes for unit to stabilize before use). 
    --Do not leave the unit on or near objects of 
    high temperature.

    

     Do not point laser directly at eye or 
     in-directly off reflective surface.

1. When taking  measurement, points 
     thermometer toward the object to be 
     measured and hold the yellow trigger. the 
     object under measuring should be larger  
     than the spot size calculated by the field  
     of view diagram.
2. Distance & spot size: As the distance from 
     the object increase, the spot size of 
     measuring area becomes larger.

3. Field of view: Make sure the target is larger 
    than the unit's spot size. The smaller the 
    target, the closer the measure distance.  
    When accuracy is critical, make sure the  
    target is at least twice as large as the spot 
    size.

How it works
   Infrared thermometer measure the surface 
   temperature of an object. The units optical 

,

   system sense the object s emitted energy  
   with different wavelength. It is collected and 

,

   focus onto a detector. The unit s electronics 
   system translated the information into a 
   temperature reading which is displayed on 
   the unit.
