Solinst Model 101D [114125] Water Level DrawDown Meter with P7 Probe & Metric Increments, 250m

The 101D Water Level DrawDown Meter has all of the same qualities as our well-known 101 P7 Water Level Meter, with the added feature of a drawdown mode. One simple toggle switches between static water level and drawdown measurements. Water level mode allows accurate depth to water measurements in wells, boreholes, standpipes and tanks. The drawdown function is used to monitor falling hydraulic head during low flow sampling, pumping and other aquifer/well tests. It also ensures a pump’s intake remains submerged during purging or well development.

Laser Marked Flat Tape
The 101D Water Level DrawDown Meter uses corrosion and chemical-resistant flat tape. The tape is non-stretch and high in tensile strength. The thick dog bone design prevents adherence to wet surfaces and allows the tape to hang straight. It is also easy to repair and splice. The 3/8" (10 mm) tape comes with permanent laser markings every 1/100 ft. or each millimeter, in lengths up to 5000 ft. (1500 m). LM2: Feet and tenths: with markings every 1/100 ft. LM3: Meters and centimeters: with markings every mm.

Water Level DrawDown Probe.
The 101D uses the same probe as the 101 P7 Water Level Meter, which is submersible up to 1000 ft. (300 m). The sensor at the tip of the probe provides consistent measurements with almost zero displacement. The tape seal plug design allows the probe to be quickly and easily replaced if required.

Reels
With a well-balanced frame, comfortable carrying handle, and handy probe holder, the standard reels are ergonomic and easy to use. They are sturdy and smooth running. The battery is housed in an easy-access drawer in the front of the reel for quick replacement. The reels are equipped with an on/off sensitivity switch, Water Level/Draw Down switch, light, buzzer, battery test button, brake and a tape guide stored on the frame.

Tape Guide/Datum
A tape guide is provided with each Meter to prevent damage to the tape from rough edges. It also ensures easy, consistent measurements regardless of who takes readings. It can also provide support for hanging small reels on the casing.
