The Japanese OPTEX PT-303 handheld thermometer is an ingeniously designed, highly practical non-contact temperature measuring tool. It features a pocket-sized design, making it extremely portable with a weight of only 200g and dimensions of 160mm×52mm×32mm. This allows it to be easily carried in a tool bag or pocket, ready to meet temperature measurement needs anytime and anywhere. The thermometer boasts a wide measurement range of -20℃～400℃, capable of handling temperature measurement tasks in various environments. With an infrared wavelength of 8～14um, a measurement spot size ratio of D:S=30:1, and coaxial laser aiming, it can accurately target the measurement object. Even at a considerable distance, it can precisely measure the surface temperature of objects. The response speed is 800ms/90%, and it can provide temperature readings in just 0.8 seconds. The measurement accuracy is ±1％or ±2℃, and the resolution is 1℃/℉, ensuring the accuracy and reliability of the measurement results. Additionally, it is equipped with a backlight design for easy reading in the dark, and a power-saving function that automatically turns off the device after about 10 seconds to extend battery life. The operating environment temperature is 0～50℃, the operating environment humidity is 35～85％RH, and the storage temperature is -20～70℃, making it adaptable to a variety of environmental conditions. The PT-303 has a wide range of applications, including electrical thermal fault detection in substations, temperature measurement in the paper and printing industry, temperature measurement in petrochemical enterprises, temperature measurement in the plastic and rubber industry, and mechanical thermal fault detection in the industrial field. It is an indispensable tool in industrial production, equipment maintenance, and quality inspection.
