Surface Resistance Testing Equipment / Insulation Material Volume Resistivity Test Apparatus

1. Performance Characteristics and Uses

ZY6156A Insulating Material Volume Resistance/Surface Resistance Testing Instrument is a portable digital display high resistance measuring instrument produced by our company. The instrument fully meets the requirements of testing instrument in insulation resistance test of national standard BG/T3048.5 wire and cable. It is used to test insulated wire and cable and other electrical products. Ideal equipment for blocking. Over the years, thousands of instruments have been used in wire and cable factories, anti-static products factories, standard measurement departments, power departments, military and scientific research units at home and abroad. They have been selected by the National Wire and Cable Testing Center and the National Anti-static Testing Center as special equipment for product type testing. Compared with similar products, it has the following characteristics:

(1) Picking up 3 1/2 digits shows that the bridge type measuring circuit has high measuring accuracy and convenient and accurate reading.

(2) Portable structure, small size, light weight and easy to use.

(3) The instrument can be operated in suspension state by battery, which completely solves the problem of high-voltage short circuit caused by grounding of water tank in wire and cable testing. It not only improves the anti-interference ability, but also avoids the concern of power line. It is suitable for the production of on-site measurement cables, and also can be supplied by external regulated power supply in fixed occasions.

(4) Built-in timer, automatic reading lock, in the test of wire and cable insulation resistance and other specified measurement time, the use is particularly convenient.
