Continuous gas flow rates for positive or negative pressure
The ADM3000 flowmeter uses the same patented acoustic displacement technology as the ADM1000 and 2000 for bubble-free, water-vapor-free operation and continuous, accurate measurements of any noncorrosive gas. Flow rates from 1.0 to 750mL/minute, positive or negative pressure, are read to ±3% accuracy. At flow rates above 20mL/minute, proprietary sensing technology enables the meter to switch automatically between positive and negative readings. At lower flows, switching is accomplished via a simple menu system. Operating temperature is 0 to 45°C with tubing temperature range of -73 to +135°C.
Meter automatically runs a self-check when turned on. Computer optimized five point calibration assures accuracy over entire flow range. Calibration is traceable to a NIST primary standard, and complete calibration documentation is shipped with the meter. To meet ISO 9000 standards, J & W Scientific offers recalibration service for these meters. Contact Krackeler Scientific for additional information.
Powered by a 9V battery (included) with automatic power off to conserve battery life (menu selectable). An AC power adapter is included for convenient long-term use. Built-in RS232 output for data logging.
