Electrical Heating Electrical Insulation Resistance Test and DC Low Resistance Test
Continuing the topic of “Characteristic Comprehensive Tester” and “Lightning Protection Component Tester”, the “Electrical Heating Electrical” you mentioned likely refers to an Electrical Heating Electrical Integrated Tester (or Electrical Heating Comprehensive Tester).
This type of instrument is a quality testing device specifically designed for electrical heating elements (such as heating tubes, PTC heating elements, solenoid valves, etc.). It highly integrates electrical performance and safety performance testing, enabling rapid completion of multiple routine factory inspections in one go.
The following are the core functions and technical features of this type of Electrical Heating Electrical Integrated Tester:
⚡ Core Testing Functions (Electrical + Thermal + Safety Integration)
The biggest feature of this type of equipment is “multi-function in one machine”, highly integrating multiple test items to avoid the complexity of using multiple instruments for scattered testing in the past:
Comprehensive Electrical Safety Test: Integrates AC/DC withstand voltage test, insulation resistance test, and DC low resistance test. For example, some advanced testers have a withstand voltage capacity of up to 500VA (5KV/100mA), and an insulation resistance test range of up to 100GΩ.
Multi-channel Resistance and Parameter Measurement: Supports rapid measurement of multi-channel DC low resistance for electrical heating elements. Some dedicated testers for PTC heating elements can also measure dimensions and resistance while obtaining surface temperature and ultimate withstand voltage value through power-on, achieving integrated testing of dimensions, surface temperature, resistance, and withstand voltage.
Inductive Automatic Testing: Equipped with an inductive start mode, the test fixture automatically starts testing after contacting the product, greatly improving the detection efficiency of the production line.
