• Gas Sample Inlet and Outlet One inlet and one exhaust out.
Optional:
• Calibration Gas Ports Separate fittings for zero, span and
sample gas input, plus internal valves for
automatically switching the gases in
sync with the 3020M electronics.
Note: If you require highly accurate Auto-Cal timing, use external
Auto-Cal control where possible. The internal clock in the
Model 3020M is accurate to 2-3 %. Accordingly, internally
scheduled calibrations can vary 2-3 % per day.
