Air velocity meter to determine volume flow rate in air and water / Two mini slow sensors selectable / USB interface / Optional software / Sensors not included in delivery. The air velocity meter P-770-M is ideal for measurement tasks which count on high precision or / and where an online record is also demanded. Thus the air velocity meter stands out due to its high accuracy of ±1 % from terminal value. Since the air velocity meter is equipped with two input channels, you can optionally connect to one of the flow sensors a temperature sensor (Pt100) simultaneously. By that the instrument is especially applicable for operation in areas of environmental technology as well as biology and laboratories. Both of the mini flow sensors can be used either to gauge the air speeds or to collect the flow-rate of water (e.g. in water or rivers). The broad application range covers measurement for purposes of quality control according to ISO 9000, as a reference device for checking production, for comparison measurements in service and maintenance, as well as long term monitoring with direct online documentation (additional software and computer data cable need to be ordered).
