• LED/LCD Display Voltage, Current
• Maximum pressure drop can be customized according to demand
• Modular structure, durable and reliable
• Low temperature coefficient: 300 ppm
• Protection and alarm function: over-temperature, open circuit, over-high and over-low
working voltage

Suitable place
• AC Current Sensor (CT), Diverter Correction, Hall Current Sensor Check
