Insulance Ohmmeter, Model ZC25, can be used to measure insulation resistance of various electrical machinery, telecommunication element, household appliances and teaching electrical equipment. ZC25型绝缘电阻表可用于测量各种电机、电讯元器件、家用电器及教学电器设备的绝缘电阻。
An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (Ω).
