This Inficon PSG500-S digital Pirani standard gauge has a 4-VCR (1/4″), 2 setpoints and stainless steel measuring cell with a tungsten filament and metal-sealed feedthrough.
The Inficon PSG5xx series gauges feature a compact, streamlined design, with a rugged aluminium housing and replaceable stainless steel sensor cell, qualifying them for use on semiconductor systems and for standard applications, such as forelines.
Measurement range (air, 02, CO, N2) is 5 x 10-4 to 1000mbar (3.75 x 10-4 to 750 Torr). One tactile switch for ATM and HV makes adjustments simple.
PSG500 series gauges can mount in any orientation and logarithmic signal output through the RJ-45 connector makes integration easy.
