Product Introduction

◉ It has two thermal resistance measurement modes: accurate measurement of absolute resistance value through built-in reference resistor, or measurement of resistance ratio (Rx/Rs) and calculation of temperature value.
◉ External high-precision standard resistors can also be used as references to achieve higher accuracy measurements or calibrate internal reference resistors.
Compared with traditional methods that use temperature measuring bridges, this instrument has the characteristics of simple wiring, convenient operation, fast measurement speed, high cost-effectiveness, and easy traceability.
Suitable for calibration and verification of thermocouples, platinum resistance thermometers, and thermistors in metrology laboratories.

Functional Features

Fast measurement speed, real-time and accurate tracking of temperature changes; The reference resistor is built into the constant temperature box of the instrument to ensure its long-term stability.
◉By advanced circuit design, the impact of stray heat dissipation potential and electrical noise on measurement accuracy can be eliminated.
The excitation current can be changed in phase, and can be set to 1 or 1.414 times the excitation current (or continuously adjustable) to automatically calculate the measured value at zero power, in order to eliminate temperature errors caused by self heating.
◉ Equipped with a large LCD touch color screen, it can display single or multiple channels simultaneously, with optional measurement units: Rx/Rs, Ω, K, ° C, ° F.
◉ Professional software (optional): Implement full/semi automatic measurement, data management, and certificate export.
