Non- contact infrared thermometer ST-380

Compact, rugged and easy to use. Just aim and push the button, read current surface temperatures in less than a second. Safely measure surface temperatures of hot hazardous or  hard–to-reach objects without contact.
How it works
Infrared thermometer measures the surface temperature of an object. The unit’s optics sense emitted, reflected and transmitted energy which is collect and focused  onto a detector. The unit’s electronics translate the information into a temperature reading which is displayed on the unit. For increased ease and accuracy the laser pointer makes aiming even  more precise.


Cautions
Infrared thermometer should be protected for the following :

  • EMF/electro-magnetic fields/ from arc 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 .

Warning
Do not point laser directly at eye or indirectly off reflective surfaces.

  1. When take measurement, point thermometer toward the object to be measured and hold the yellow trigger. The object under test should be larger than spot size calculated by the field of view diagram.
  2. Distance and spot size : as the distance from the object increase the spot size of measuring ares becomes larger.
  3. Field of view : make sure the target  is larger than the unit’s spot size. The smaller the target the closer measure distance. When accuracy is critical, make sure  the target is at least twice as large as the spot size .
  4. Emissivity: most organic and painted  or oxidized  surfaces have an emissivity  of 0.95. Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted reach the same temperature as the material underneath.

  1. Maintenance
  • Lens cleaning: blow off close particles using clean compressed air. Gently brush remaining debris away with a moist cotton cloth.
  • Case cleaning: clean the case with a damp sponge/ cloth a mild soap.

Note :

  1. Do not use solvent to clean lens.
  2. Do not submerge the unit in water.
