From the Manufacturer

Ground Resistance Meter MODEL 4102-HA (with Hard Case)

Kyoritsu Electric

Since its establishment in 1940, Kyoritsu Electric Instruments Co., Ltd. has consistently made products and services to customers first, and established their trust in each other.

During this time, electrical measurement technology has played an important role as the foundation of technology development and industry that supports the development of the world.

Ground Resistance Meter MODEL 4102A-H (with Hard Case)

Simple measurement (2 polarity) and A-D (3 polarity) can be measured.

Conforms to the latest JIS C 1304:2002.

·Measurement error is not possible even if the resistance of the auxiliary ground electrode is large. The nominal usage range of 0 to 100 x ground resistance value (upper limit is 50 kΩ) has been revised to (JIS C 1304:1995 to determine the effects of 0Ω, 2kΩ, 5kΩ).

Includes warning function that allows you to check the resistance of the auxiliary ground electrode (LED warning) (no items in JIS C 1304:1995)

In addition to precise measurements, the probe for simple measurement is also included as standard (you can easily measure the device while it is placed on your neck. )

Dustproof even in light rain.
