Insulation Resistance Meter Series

Insulation Resistance Meter Series

Improve work efficiency with a lead that has a switch! An insulation resistance tester that allows for smooth start and stop operations.

We would like to introduce our "Digital Insulation Resistance Tester." It efficiently manages measurement data via Bluetooth communication and features a switch-equipped lead to improve work efficiency. It also includes convenient measurement functions for low resistance measurements and AC/DC voltage measurements during inspections. Additionally, it evaluates the measurement values against a user-defined reference value, and if the measured value does not meet the reference, it alerts you with a red light and a buzzer sound. 【Features】 ■ Efficient management of measurement data via Bluetooth communication ■ Improved work efficiency with switch-equipped leads ■ Notification of judgment results through light and sound ■ Convenient measurement functions for inspections ■ Prevention of high voltage application due to misoperation *For more details, please refer to the PDF document or feel free to contact us.

Analog High Voltage Insulation Resistance Tester 'KEW 3124A'

Analog High Voltage Insulation Resistance Tester 'KEW 3124A'

Variable output voltage with the setting knob! Very easy-to-read structure from low resistance values to high resistance values.

The "KEW 3124A" is an analog high-voltage insulation resistance tester that can be set to any output voltage in the range of 1kV to 10kV. Upon completion of the measurement, the charge stored in the circuit is automatically discharged. The residual voltage value is monitored by the output voltmeter, allowing you to confirm the discharge status. Additionally, it uses three power sources: a built-in battery (nickel-hydrogen battery), AC 100V, and a vehicle battery, enabling charging while the rechargeable battery is installed. 【Features】 ■ Variable rated measurement voltage ■ Auto-discharge function ■ Three power source system ■ Insulation resistance measurement possible with G terminal grounding method *For more details, please refer to the PDF document or feel free to contact us.
