Wide range of household and equipment use Suitable for measuring temperatures on engines, tires, electrical equipment, heating and cooling systems, hot furnaces, and everyday hot water or oil in cooking, as well as temperatures of refrigerators, TVs, air conditioners, conditioners and other products. accuracy with fast response Object distance of 12:1 allows measurements from a long distance. sensors provide results in under 0.5 seconds. Measurement accuracy is +/1.5% or +/1.5°C, suitable for most everyday applications. Modes and functions for versatile use Use the mode switch to select MAX, MIN, AT, or CAL. MAX: displays the temperature reached during measurement. MIN: displays the lowest temperature reached during measurement. AT: automatically displays the current temperature. CAL: temperature calibration. Tolerance can be adjusted from 0.1 to 1. Practical benefits Noncontact temperature readings from a safe distance. Quick, reliable readings with clear mode indicators. Flexible for everyday life tasks and routine maintenance. Use scenarios Automotive and equipment inspection: monitor engine or component temperatures and check tire temperature from a safe distance. Home appliances and HVAC: verify temperatures of hot water, cooking oil, refrigerators, air conditioners, and other appliances to ensure proper operation. Maintenance and safety checks: use MAX/MIN to assess temperature ranges during system operation and CAL to calibrate measurements for accuracy. Notes The device offers a longdistance measurement capability, fast response, and precise readings, with modes designed for monitoring extremes, current temperatures, and calibration.
