NA2671 Series Pointer Insulation Resistance Tester
Product introduction 
With the rapid development of National power industry, electrical equipment preventive experiment is an important part in protecting the safety operation of power system and maintenance. Insulation diagnosis is an important method to detect insulation defects or failure. Pointer insulation resistance tester is the special instrument to measure insulation resistance. JJG662-89 "insulation resistance meter (megger)" approved in May 1990 requires that insulation resistance meter is one of compulsory verification instruments. Nowadays the development trend of electrical equipment (such as transformers, generators, etc.) is that high capacity, high voltage, diversified structure and better seal. So insulation resistance meter (pointer) itself must have the characteristics such as large capacity, strong anti-interference ability, diversified measurement indexes, accurate measurement results, easy and fast measurement process, easy to carry and so on. The instrument produced by our company is equipped with ultra-thin taut suspension meter. It is an ideal tester to measure insulation resistance of these equipment such as transformer, instrument transformer, generator, HV motor, power capacitors, power cables, arrester, etc

The Characteristics of the products
(1) The instrument is used to do insulation test: when the voltage is 500V, the maximum tested value will up to 20GΩ; when the voltage is 1000V, the value will up to 40GΩ; when the voltage is 2500V, the value will up to 100GΩ.
(2) When rated output voltage of NA2501 tester continuously load, the resistance can be as low as 4MΩ/8MΩ/20MΩ, which makes the instrument can measure the low insulation resistance accurately.
(3) Double scale indication can be converted automatically, colorful LED display for easy reading.
(4) ABS plastic casing and portable design with anti-interference ability, compact structure, attractive appearance.
(5) The instrument uses ultra-thin sheets silk headers, seismic resistance.
(6) AC-DC dual-use, built-in rechargeable battery and intelligent charging module, ensuring high output power(C type).
(7) It is an ideal tester to measure insulation resistance of these equipments such as transformer, instrument transformer, generator, HV motor, power capacitors, power cables, arrester, etc.
