Want to use the simplest flowmeter for gas chromatographic analysis? ADM flowmeters allow most gas measurements with the touch of only one button—turn it on, and the instrument provides continuous, hands-free flow readings. You can measure column, detector, and carrier gas flows without any adjustments. ADM flowmeters are ideal for measuring gas streams with a changing gas composition. For example, if you measure the gas flow from a digestion system, concentration changes in methane, carbon dioxide, and oxygen will not affect accuracy.
All ADM flowmeters are battery powered and field portable. Agilent calibrates each instrument to 5-point, NIST-traceable standards to ensure the highest available accuracy. The ADM family measures flow volumetrically, so you don’t have to make any adjustments when changing from one gas to another. Agilent recommends calibrating ADM flowmeters once a year.
If you need rapid, real-time measurements of a gas stream, ADM Flowmeters are perfect for you. These flowmeters are designed for basic gas chromatography laboratories.
ADM 1000
Accuracy +/-3%
Operating temperature range— 0 to 45°C for the instrument, -70 to 135°C 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 measurements to another (i.e., injection port split ratios)
ADM 2000
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
Data output through RS-232 port
9V battery and AC power adapter (120 or 220 VAC)
