Integrated electronic flowmetre enables real-time flowrate values to be digitally displayed
Constant flow rate function automatically controls changes in flow rate caused by variations in load
Automatic shut-off of air pump by preset timer; digital display of integrated flow rate
Automatic shut-off of air pump at preset volume; digital display of elapsed time
Displays instantaneous and integrated flow rate as well as elapsed time during air pump operation as set for both the timer and constant volume modes
Automatic calibration of instantaneous and integrated flow rates to appropriate values at 20ºC24-hour continuous fixed volume sampling (equipped with Ni-Cad cell, no external AC power source required)
Employs a quiet air pump
One-touch switching from timer to fixed parameter mode
