Informasi Produk

Description
The Metravi CAL-ER Calibrator is used for calibrating grounding resistance testers,
equipotential testers and other instruments which require a standard resistor.
It is widely used in building quality inspection stations, supervision companies, construction
companies, lightning protection companies, electric power departments, etc.
Feature
The military grade instrument is composed of 9 pieces of 1/2w, high-precision, military-grade wirewound resistors.
It has stable performance and strong structure, especially convenient for calibration & testing.
When calibrating resistors, one can direct shift and test without replacing the test line.
Fully meets the national weather service order "lightning protection device detection qualification management approach" specified in the range of 10-3 ~ 105 Ω.
