PM1508 is a digital insulation resistance tester powered by battery. It is controlled by microprocessor chip and has high precision, stability and reliability. The insulation resistance measurement has 5 range test voltage output, the maximum insulation resistance measurement is 100GΩ, and the basic accuracy can reach ± 1.5%, which can meet more application test needs of customers. In addition to insulation measurements, ACV, DCV, frequency and low resistance measurements can be performed. It is mainly used in transformer, motor, generator, cable, electrical and other electrical equipment and insulation material measurement. The design is exquisite, durable and easy to operate, making it an ideal tool for many occasions of maintenance, debugging and preventive maintenance.
