Features: 1.Dual Temperature Measurement Display: Dual temperature thermometers use two sensors, one inside the device and the other extended to an external probe, which is waterproof. Both sensors can measure temperature simultaneously and display it on the software interface. 2.Hyperbola Display: The real time temperature inside and outside is converted into a hyperbola, and the temperature monitoring is more clear and clear. 3.Log Function: Real time temperature data can be recorded and automatically saved in related files. 4.Warning Setting: Set the warning temperature and start the function. When the temperature reaches the upper limit, the warning sound will play; then when the temperature drops to the lower limit, the warning sound will stop. 5.Wide Range Of Applications: It can be used for indoor and outdoor temperature detection, computer room warehouse environment monitoring, various large shopping malls, pharmacies, air conditioning temperature control monitoring, breeding farms, vegetable greenhouse temperature monitoring and other areas, product and accessories surface temperature detection. specification:Item Type: USB Computer Thermometer Material: ABS Probe : TX Temperature Probe 4pin Probe Length: Approx.30mm / 1.2in Line Length: Approx.1m / 1.1yd Temperature Resolution: 0.06 Temperature Accuracy: 2 Measuring Temperature: -40~+125 Compatible System: for Windows PackageList: 1 x Thermometer 1 x Dust Hat 1 x Probe 1 x Disk Drive
