Description:

The ADM-1000 uses a micro-thermal mass sensor to read GC carrier, make-up or split flows independent of temperature and pressure changes. Auto-ranging firmware displays flow with 0.1 mL min⁻¹ resolution below 10 mL min⁻¹ and 1 mL min⁻¹ up to 500 mL min⁻¹. A single-button operation and 10-minute auto-off conserve the 9 V alkaline battery, good for ~40 h of continuous sampling. The sensor is factory-calibrated for He, H₂, N₂, Ar/CH₄ mixes and air; gas selection cycles with the MODE key. A barbed stainless inlet swivels 360°, allowing vertical readout no matter how the column exit is oriented.

Economic Advantage:

Replacing bubble burettes, the ADM-1000 cuts a two-minute manual measurement to five seconds, preventing costly carrier-gas waste and analyst error; the low-maintenance cartridge sensor needs annual swap only, avoiding third-party calibration fees.
