Model 9110T NOx Analyzer Getting Started

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).
