Wholesale Ice Point Thermometer Calibration - PR721/PR722 Series Precision Digital Thermometer – Panran
Wholesale Ice Point Thermometer Calibration - PR721/PR722 Series Precision Digital Thermometer – Panran Detail:
PR721 series precision digital thermometer adopts intelligent sensor with locking structure, which can be replaced with sensors of different specifications to meet different temperature measurement needs. The supported sensor types include wire-wound platinum resistance, thin-film platinum resistance, thermocouple and humidity sensors, which can automatically identify and load the type, temperature range and correction value of the connected sensor. The thermometer is made of aluminum alloy as a whole, with IP64 protection class, which can be used reliably in harsh environments.
Technical Features
- Smart sensor, the temperature range covers -200~1300℃. Using high temperature-resistant locking components, the host can automatically load the current sensor type, temperature range and correction value after connecting to the smart sensor, improving the accuracy of temperature traceability, and work efficiency.
- Low temperature drift, in the range of 5~50℃, the electrical measurement accuracy is better than 0.01, and the resolution is 0.001℃, which can meet the high standard temperature calibration requirements.
- In U disk mode, charging or data transmission can be performed through the Micro USB interface, which is convenient for quick editing of test data.
- Gravity sensing function, supports automatic screen flipping, and ideal reading experience can be obtained by placing it left or right.
- Support Bluetooth or ZigBee communication, you can use Panran Smart Measurement APP to synchronize data or expand other applications.
- Protection class IP64 for reliable use in harsh environments。
- Ultra-low power consumption, built-in rechargeable lithium battery, continuous work for more than 130 hours.
