This product is an technical grade thermal infrared Tempilstik, realize long-distance non-contact precision temperature measurement. Widely applicable: water temperature, oil temperature, indoor planting temperature, laboratory equipment temperature, boiler temperature, power equipment temperature, metallurgical temperature, pipeline temperature, factory equipment temperature, transportation and maintenance, etc. Lightweight and easy to carry, the length is 12.7cm and the weight is 65g. The Sensor made in German, tolerance is only ±0.1℃, the reaction speed is 0.5 seconds, and it can be read continuously and quickly. The measuring distance is very long, and effective range is 3~18 cm, reducing the risk of personnel's close temperature measurement. Using ambient temperature compensation algorithm, automatic calibration after use. The measurement can be started quickly with a single key, and it is easy to use. It has temperature abnormality warning function, when the temperature exceeds the temperature of set, it will emit warning sound to remind.
