Sientific portable flowmeter, air flow, water flow, temperature!
Developed for use under various challenging field conditions. Its different impellers measure almost any fluid, liquid or gaseous medium. Fluid 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. 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 optional flow sensor with 15 meter cable (sold separately). Kit includes the display, 1.2m aluminum telescoping rod with 2m cable, a 60mm water impeller, 20mm air impeller and carrying case. Weatherproof.
