KLY meters are direct acting analog electrical measuring instruments. They are mainly used on the distribution, control panel of power plant and other different apparatus to measure current, voltage, frequency, power, power factor, synchroscopes. Phase sequence and other non-electric values The digital meters measure and display the current, voltage, frequency, power, power factor in electric power network and automation control system Operating Temperature KLY Series:-25C~+55C CP Series:-20C~+40C Storage Temperature -40C~+70C
