Sampling Method
Diffusion
Flow Rate for
Calibration
0.25 LPM (using a 0.5 LPM regulator that is normally recommended
for M2A-XLs will result in an inaccurate calibration)
Input Power
10 - 30 VDC
Controls
• Three push button switches
• Three magnetic switches for non-intrusive calibration
Weight
5.5 lbs.
Signal Output
4 to 20 mA with impedance maximums listed below
• -12 VDC: 500 ohms impedance max
• -24 VDC: 1000 ohms impedance max
