Dielectric constant and dielectric loss tester
yle=font-size:14px; yle=font-family:trebuchet mshelveticasans-serif; yle=color: rgb(0 0 0); HQS37a is mainly used to measure the tangent value and cap
Product details
Classic test lines have a wider measurement range
Using the Xilin bridge principle, the maximum test voltage is 2500V
The bridge itself has a standard capacitor of 5kV/100pF, making it more convenient to measure the dielectric loss of the material.
The bridge body is equipped with a potential tracker and indicator, with few peripheral wiring.
The bridge body adopts diversified dielectric loss measurement lines.
High measurement accuracy and stable performance

Measuring fixtures is more convenient
This electrode is suitable for testing the relative dielectric constant (ε) and dielectric loss tangent (tg δ) of solid electrical insulation materials such as insulation paint, resin and adhesive, impregnated fiber products, laminated products, mica and its products, plastics, cable materials, film composite products, ceramics, and glass. This electrode is mainly used to measure the relative dielectric constant (ε) and dielectric loss tangent (tg δ) of the test sample at a frequency of 50Hz. The design of this electrode is mainly based on the national standard GB1409-78.
This electrode adopts a three electrode structure, which can effectively eliminate the influence of surface leakage current and make the electric field under the measuring electrode tend towards a uniform electric field.
