Gas Management
• Accuracy ± 3%.
• Operating temperature range – 0 to 45ºC for the instrument, -70 to 135ºC
for the tubing.
• Calibration – traceable to NIST primary standards.
• Real time, split ratio measurement.
• CE mark certified.
• Measures flow rates from 0.5 to 1000 mL/min.
• Split ratios – compare the ratio from one gas measurement to another
(i.e., injection port split ratios).
In addition to the features of the ADM 1000, the ADM 2000 includes:
• Mass flow measurements – measure flow rate, independent of atmospheric pressure
and temperature (calculated).
• Data output through RS-232 port.
• 9V battery and AC power adapter (120 or 220 VAC).
