Use the flow rate Sensor to easily measure stream velocity<br />
for environmental or earth science studies. flow rate data<br />
can be used to calculate the discharge value for the stream<br />
or study the sediment transport of the stream.<br />
• Separates into four sections for easy transport and<br />
convenient storage.<br />
• equipped with a 5 m cable, so your data-collection<br />
equipment can stay on shore.<br />
• includes 3 riser rods, which enable the impeller to be<br />
placed at fi xed depths.<br />

the force Plate is a large force sensor—tough enough<br />
to jump on. About the size and shape of a bathroom<br />
scale, the force Plate has two ranges, one reading up to<br />
3500 n and the other to 800 n. two handles are included<br />
for pushing or pulling. additional pairs of handles are<br />
available (orDer coDe fP-han, $15).<br />
