Product Description

ETCR3440B Insulation Resistance Meter is a digital insulation resistance tester. It has high accuracy, simple and reliable operation, and easy to use. According to different models, the output test voltage 1000V/2500V can be switched. 

Ordinary insulation resistance meter can not measure its own output high voltage, in the insulation resistance meter output high voltage does not meet the rated value, the user is not easy to find, so that sometimes the measurement results 

deviation is too large, resulting in safety hazards, it can be timely monitoring of the output high voltage, the user at any time can observe the actual output of the instrument measurement voltage, to effectively avoid misjudgment caused by 

the output voltage is not in line with the requirements of the rated value. The measuring range of the meter can reach up to 40GΩ, and the measuring time can be set according to the need, and the measuring result will be kept automatically 

after the measurement is finished or when any key is pressed during the measurement. This product is suitable for measuring the insulation resistance of transformers, motors, cables, switches, electrical appliances and other electrical equipment 

and insulating materials, maintenance and repair of various electrical equipment, testing and calibration. It has a compact structure, easy to carry, is your ideal electrician, electronic test instrument.
