Tape & Probe Specifications

Laser Marked Flat Tape

The Solinst 105 Well Casing & Depth Indicator uses corrosion and chemical-resistant flat tape. The tape is non-stretch and high in tensile strength to support the heavier 105 Probe. 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 10 m (3/8") tape comes with permanent laser markings every each millimeter or every 1/100 ft., in lengths up to 600 m (2000 ft.).

LM2: Feet and tenths: with markings every 1/100 ft.
LM3: Meters and centimeters: with markings every mm

Well Casing & Depth Indicator Probe

The 105 Probe is made from 316 stainless steel and is submersible the full length of the tape. It contains a strong internal magnetic assembly to detect metal casing and a plunger assembly to measure total well depth. The tape seal plug design allows the probe to be quickly and easily replaced if required.
