AstroAI Infrared Thermometer Manual

by
Thank you for purchasing the Infrared Thermometer from AstroAI. This infrared thermometer is used for measuring the temperature of an object’s surface. Use in hot or hazardous situations safely with a non-contact thermometer. For optimal performance and safety, please read and follow all of the instructions below before operating the device. Please keep this manual for future reference. We hope you enjoy your new Infrared Thermometer!

WARNING

  • BEFORE USE: Check the plastic housing carefully for any damage. Do not use if plastic housing is damaged.
  • DO NOT point laser directly in eyes or indirectly off of reflective surfaces.
  • DO NOT use in environments with explosive gas, steam, or dust.
  • DO NOT use this product for applications outside of its intended use.
  • AVOID situations with EMF (Electro-Magnetic Fields) such as arc welders and induction heaters.
  • AVOID thermal shock caused by large or abrupt ambient temperature changes. Allow at least 30 minutes for unit to stabilize temperature before use.
  • DO NOT leave unit on or near high-temperature objects.
  • Read and follow all instructions before use

INSTRUCTIONS

Operating:
  1. Open the battery door and insert a 9V battery.
  2. Press the trigger to turn the unit on.
  3. Aim the laser at the target surface and pull trigger.
  4. Temperature reading will be displayed on LCD.
Locating a Hot Spot:
  1. Press trigger to turn unit on.
  2. Aim thermometer outside of the hot spot.
  3. Scan across with up an up and down motion until hot spot is located.
Distance to Spot Ratio
  1. Pay close attention to the Distance to Spot Ratio.
  2. As the Distance (D) from the target surface increases, the Spot Size (S) of the are being measured becomes larger.
  3. The Distance to Spot Ratio of this unit is 12:1. This unit is equipped with a laser, which is used to assist with aiming.
Field of View: To increase accuracy, make sure the target surface is larger than the Spot Size. When accuracy is critical, make sure the target surface is at least twice as large as the spot size. Emissivity Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set) in the unit). Measuring shiny or polished metal will result in inaccurate readings. To compensate for these inaccuracies:
  1. Cover the target surface with masking tape or flat black paint.
  2. Allow the tape or paint to reach the same temperature as the target surface.
  3. Measure the tape or painted surface.

MAINTENANCE

Lens Cleaning:
  1. Blow off loose particles using clean compressed air.
  2. Gently brush remaining debris away with a moist cotton swab moistened with water.
Case Cleaning:
  1. Clean with a damp sponge/cloth and mild soap.
NOTE:
  1. DO NOT use solvents or strong cleaning agents when cleaning plastic lens.
  2. DO NOT submerge the unit in water.
