The new Edwards Linear Convection Gauge has a wide measuring range from 1333 to 3 x 10^-4 mbar (1000 to 2.3 x 10^-4 Torr). The use of convection technology ensures, accuracy and sensitivity are maintained to the top of the range. The gauge is compact and may be mounted in any orientation, simplifying installation where space is limited. The gauge incorporates a set point and two LEDs, which indicate set point and gauge status. For reduced cost of ownership, the gauge is provided with a replaceable tube, in which calibration data is stored. They are also CSA and C/US approved as well as fully RoHS compliant due to their lead-free construction.                Edwards APGX-H- Brochure
