DCT501 Dielectric Constant Tester

Introduction

Dielectric Constant Tester can test medium loss and dielectric constant, which are an important physical property of materials such as metal oxide, plank, porcelain (pottery), mica, glass, plastics, etc. Through measurement, the various factors of dielectric loss and dielectric constant can be further understood, providing conditions for improving the properties of materials.The equipment is used for applied research of inorganic metal new material properties in scientific research institutions, schools, factories and other institutions.

Application range

Measure the dielectric constant and dielectric loss coefficient of insulating materials (loss tangent value)

Unique technology

Automatically deducts residual inductance and test lead inductance. Significantly improve measurement accuracy.
Large capacitance value is directly measured and displayed.
Digital microscopic measuring device, direct reading.
