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
(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.
