The standard model dip meter is ideal for the measurement of ground water levels. This particular model is strictly for use with non hazardous and non harsh water conditions, and thus is more cost effective than the advanced models if you are only carrying out monitoring in basic liquid water such as in aquifers and untouched sources. The probe is made from stainless steel so will not rust, while the tape is made from moderately strong polyethylene. The tape also has graduation markings all along it. The scale is printed in black, unitary numbers in red and graduations such as Meters, centimeters, millimeters and unitary meters are also in red, other markings are in black. The entire piece of equipment is easily powered by a standard 9 volt battery and the probe can be used in liquid up to 150 degrees celsius. Available with various cables lengths.
