Platinum resistance thermometers are widely used in laboratory physical measurement, chemical industry, aerospace and HVAC industry to accurately measure temperature and provide a safe and reliable measurement experience.

Features

• The resolution of the high-precision thermometer can reach 0.01℃, and the platinum resistance probe is used to provide extremely high measurement accuracy.
• The platinum resistance thermometer is equipped with an over-limit sound and light alarm function. When the temperature exceeds the set value, an alarm sound is issued and the screen flashes.
• It supports autonomous temperature calibration, and users can customize calibration as needed.
• It supports calibration of two sets of probes, each set of probes provides 20 calibration points to ensure measurement accuracy.
• The thermometer can replace independent probes, and users can replace the corresponding probes according to measurement needs for different temperature measurements.

Tips: Principle of platinum resistance thermometer

The principle of platinum resistance thermometer is based on the characteristic that the resistance of platinum metal changes with temperature. Specifically, the resistance of platinum increases with the increase of temperature, and has a good linear relationship. By measuring the resistance value of the platinum resistor, its corresponding temperature can be accurately calculated. Typically, platinum resistance thermometers use a known resistance-temperature relationship (such as the Huhr curve) to calculate the temperature value, which makes them highly accurate and stable over a wide temperature range.
