Crown Test GEST-121A resistivity tester

1、 Overview

This instrument can measure both high resistance and micro current. Adopting large-scale integrated circuits from Intel Corporation in the United States, the instrument has a small size, light weight, and high accuracy. The digital LCD directly displays the resistance value and current. The measurement range is from 1 × 104 Ω to 1 × 1018 Ω, making it the widest and most accurate digital ultra-high resistance measuring instrument in China. The current measurement range is 2 × 10-4 to 1 × 10-16A. The internal test voltage is adjustable from 10V/50V/100V/250V/500V/1000V. This instrument has high accuracy, fast display, good stability, and convenient reading. It is suitable for measuring the volume and surface resistance values of various insulation materials such as rubber, plastic, film, powder, liquid, solid, and paste shapes. This instrument can not only measure resistance, but also directly measure weak currents.

2、 Main features

The resistance measurement range is wide from 0.01 × 104 Ω to 1 × 1018 Ω

The current measurement range is 2 × 10-4A to 1 × 10-16A

Small size, light weight, high accuracy

Dual display of resistance and current

Good and stable performance, easy to read

All test voltages (10V/50V/100/250/500/1000V) require direct reading of resistance results, eliminating the inconvenience of using old-fashioned high resistance meters to multiply coefficients at different test voltages or ranges. This makes measuring ultra-high resistance as simple as using a multimeter to measure ordinary resistance samples.

Can measure both ultra-high resistance and microcurrent
