Procurement of portable infrared thermometer
PT series portable infrared thermometers are easy to operate and high-quality infrared thermometers with an accuracy of less than 1% and a measurable temperature range covering -25 ° C to 3000 ° C, which basically meets the needs of temperature measurement in various industries and has been widely Applications.
The PT40, PT50, and PT70 long-wave red thermometers are full-featured and can easily detect electrical equipment, engines, and HVAC and air-conditioning systems. They are the best choice for close-range temperature measurement.
＊ Mini design, beautiful and elegant, fast response and easy operation.
＊ Laser aiming is safe and reliable. PT70 is coaxial laser aiming.
PT90, PT120, PT150 are high-performance handheld long-wave red thermometers. The instrument has a wide temperature measurement range, which can meet the different needs of users in the range of -25 ° C to 1500 ° C. They are coaxial laser aiming, which can accurately measure the temperature of the target, stable repeated measurement, fast response speed, simple operation and reliable use.
* Wide temperature measurement range, high measurement accuracy, fast response speed, coaxial laser aiming.
＊ Precision infrared optical system processed by high-tech means with large distance coefficient
PT300 and PT300B are high-performance hand-held medium and high temperature short-wave red thermometers. The telescope is aimed visually and the precision focusing optical system can penetrate glass to accurately measure the minimum target temperature of 5mm.
＊ Wide temperature range of 400 ℃ ～ 3000 ℃, large distance coefficient of 120: 1, fast response.
＊ Instantaneous value, maximum value, minimum value, average value and temperature difference value display, sound and light alarm for temperature over limit.
