Digital Pirani Gauges are specialized monitoring instruments designed for the accurate measurement of high vacuum in the Pirani Range upto 0.001 mBar. The indicator is panel mounting type with a Pirani Gauge Head ( Sensor ) which can be clamped onto the point of measurement using a KF Clamp fitting. The instrument measures accurately in the Pirani vacuum range from 999 mBar ( Atmospheric ) to 0.001 mBar ( 1 micron ). The Digital Pirani Gauge has an intelligent microcontroller design & the display is a 4 Digit 7 segment LED display with auto decimal resolution setting. All Pirani Gauges are based on the principle of measurment of thermal conductivity of gases. The Digital Pirani Gauges come with a single gauge head or an optional dual gauge head enabling the use of one instrument to measure the vacuum of 2 points. The Digital Pirani Gauge is a direct replacement for the conventional Analog Pirani Gagues & is mains operated on Single Phase , 230 V.A.C. supply
