105 Well Casing & Depth Indicator

One probe that detects metal well casing and measures total well depth.

Dual-function 316 stainless steel probe with magnetic casing detection and a total well depth plunger
Non-stretch, laser marked flat tape in lengths up to 600 m (2000 ft)
Buzzer and flashing red light signals on a well-balanced reel

Quantity

Overview

The 105 Well Casing & Depth Indicator detects metal well casing and measures total well depth with one dual-function stainless steel probe, connected to clearly marked flat tape on a well-balanced reel. A strong internal magnetic assembly detects well casing, while a plunger at the bottom of the probe signals total well depth. It is useful for determining where metal casing starts and ends in new or existing well constructions, hydrofracturing, and installing packers or other downhole instruments.

Typical applications

Measuring total well depth
Groundwater well installation
Detecting gaps in well casing
Installing telescoping well screen
Packer and downhole instrument installation
Hydrofracturing
Confirming existing well construction
Decommissioning abandoned wells

Key Features

One probe for both well casing depth indication and total well depth measurement
316 stainless steel probe with a strong internal magnetic assembly and a plunger assembly
Non-stretch, accurately laser marked flat tape
Tape lengths up to 600 m (2000 ft)
Tape accuracy meets NIST and EU measurement standards
Replacement tapes are interchangeable with other Meters
Buzzer and flashing red light signals, with a battery test button

Benefits

Two functions, one probe: Detects metal well casing and measures total well depth without switching out the probe
Clearly marked tape: Non-stretch flat tape with permanent laser markings every millimeter or every 1/100 ft
Durable tape: Corrosion and chemical-resistant, high in tensile strength, and easy to repair and splice
Easy-to-use reel: Well-balanced frame with carrying handle and probe holder, plus an easy-access battery drawer for quick replacement
Consistent readings: The tape guide protects the tape from damage and provides an accurate measurement point, regardless of who takes readings
Quick probe replacement: The tape seal plug design allows the probe to be quickly and easily replaced
