The Model 102/P4 Water Level Meter uses a choice of two small diameter probe designs, attached to a narrow coaxial cable, fitted on a sturdy ergonomically designed reel. A standard 9-volt battery, housed in an easy-access battery drawer, powers the Water Level Meter.
Model 102 Probes are designed without the weights at the edge of the cable, unlike the 102/P10. The probe tip uses a recessed design to minimize false signals in cascading water.
Providing the famous quality of Solinst groundwater-measuring instruments at an introductory price, the Solinst 102/ P4 is built for long life and laser-marked for accurate readings every time. The Solinst model 102/P4 offers professional accuracy in unique situations, including in narrow shafts and when maneuvering around in-well pumps and other obstacles. Measurements are traceable to national standards, and each unit is calibrated at a National Institute of Standards and Technology (NIST)-certified lab.
Laser Marked Cable
The coaxial cable has a durable polyethylene jacket with permanent markings precisely laser etched on the cable every 1/100 ft. or each millimeter. The cable reels smoothly remain flexible and come in lengths from 100 ft. - 300 ft. (30 m - 100 m). A braided copper outer conductor gives flexibility and a stranded stainless steel central conductor gives strength. It is easy to repair and splice
Model 102 with the P4 Probes are designed for flexibility. The probe tips use a recessed design to minimize false signals in cascading water.
P4: 0.157" dia. x 1.5" long (4 mm x 38 mm) stainless steel weighing 0.35 oz (10 g), with no weights. It is ideal for shallow applications and for accessing very narrow diameters, especially the channels of the Solinst CMT System, DrivePoint Piezometers or narrow open tubes.
