3.3.2.4. Connections w/Ambient Zero/Pressurized Span Valves (OpT 50B)
This calibration valve package is appropriate for applications where Span Gas is being supplied from a
pressurized source such as bottled NIST SRM gases. This option includes:
A critical flow orifice and vent that maintains the Span Gas supply at 1 ATM.
A SHUTOFF valve to preserve the Span Gas source when it is not in use.
Two solenoid valves located inside the analyzer that allow the user to switch either zero, span or
sample gas to the instrument’s sensor.
Three additional gas inlet ports (ZERO AIR, SPAN and VENT).
