Digital Flow Meter

Ideal for educational use as well as for work in remote locations. The probe folds down into 3 separate sections measuring 16" each. This collapsible design allows you to easily pack the flowmeter in a backpack. Flow measurements can be taken in knots, km/h, mph, and m/s. The meter also takes temperature measurements in either °F or °C, including minimum and maximum temperature and current temperature. The basic unit includes meter, foldable probe, standard flow sensor and carrying case.

Also included is a wind speed impeller which allows you to take air velocity and wind chill measurements. To take flow measurements from a bridge or other elevated location, use the flow sensor with 15 meter cable (purchase seperately). The unit automatically turns itself off after 36 hours. Power: CR2032 Lithium battery (included). Provided with Backlight .
