LINEAR CONVECTION GAUGE (APGX-H) Edwards Linear Convection Vacuum Gauge has a wide measuring range technology ensures accuracy and The gauge is compact and may be mounted in any orientation, simplifying installation where space is limited. The gauge incorporates a setpoint and two LEDs, which indicate setpoint and gauge status. • Wide Measuring Range • Consistent Measuring Accuracy - Use of convection technology ensures consistent measuring accuracy (typically ±15%) • Reduced Cost of Ownership - Replaceable tubes are available • Standard Analog Output • Calibration Data Held in Tube - Tubes are shipped pre-calibrated • Easy Installation in Restricted Spaces - Maintains accuracy in any orientation across the whole measuring range • Compact Instrument - Significantly smaller than leading competitor convection gauges • Local Status Indication - LEDs indicate setpoint and gauge status at the gauge head
