0.001 to 10 Torr Range
If Pirani gauge's principle supplies constant voltage to sensor's filament that is established to vacuum chamber, because resistance value according to change of pressure of vacuum changes, it is principle to convert by pressure of vacuum change of flowing current to sensor.
Improved accuracy about sensor using 10bit AD converter.
Improved interior corrosion and oxidation by Sensor filament's gold coating.
improved voltage stability and authoritativeness by SMPS power supply type.
External appearance is elegant, and added Analog output DC 0 ~ 5 V by FND display type

These compact vacuum measurement and control instruments offer the precision and high resolution of digital electronics at the same price as analog instruments. Our extremely rugged sensor is constructed with a solid, inert noble metal that maintains its calibration over long periods. Because no gold is used, these gauges are compatible with both mercury and oil pumps. The Low 125℃ operating temperatures in our Pirani- Type gauge tube(half that of thermopile gauges), enhances stability as does a unique temperature compensation network. Gauge tubes are matched and can be replaced without recalibration, and they can withstand working pressures to 300 psi, Tested to 1200psi.
