A. Product Overview
A portable handheld thermometer with RTD sensor is used to measure temperature accurately in different industrial and scientific applications. RTD stands for Resistance Temperature Detector, which is known for excellent accuracy, long-term stability and reliable repeatability.
This thermometer is designed for easy carrying and one-hand operation. It usually comes with a clear digital display, simple buttons or user interface, ergonomic body and durable housing for field use. Depending on the RTD sensor type and application requirement, the temperature range can typically cover from minus 200 degree Celsius to 600 degree Celsius or higher.
Handheld RTD thermometers are widely used where accurate temperature checking is required on-site, in production areas, laboratories, maintenance departments and process industries.
B. Working Principle
The handheld thermometer works with an RTD sensor, which changes its electrical resistance according to temperature. When the RTD probe comes in contact with the object, surface, liquid or process area, the sensor detects the temperature change.
The thermometer measures the resistance value from the RTD sensor and converts it into a temperature reading. This reading is then shown on the digital display in the selected temperature unit.
RTD sensors are preferred because they provide stable and accurate readings compared to many general-purpose temperature sensors. Depending on the model and sensor quality, handheld thermometers with RTD sensors can offer accuracy from plus or minus 0.1 degree Celsius to plus or minus 1 degree Celsius, with resolution ranging from 0.1 degree Celsius to 0.01 degree Celsius.
