Hocking Locator 2s 

Single Frequency Eddy Current Instrument with Conductivity and Coating Thickness Measurement 

Locator 2s is a single frequency eddy current instrument and succeeds the highly popular Locator 2. Locator 2s is the latest in hand held eddy current inspection, designed with the needs of the operator in mind. Its lightness (only 0.94kg), unique keypad controls, ease of programming and particularly its big screen mean lots of inspections with little fatigue. The large LCD display can be seen clearly under any light conditions, even direct sunlight and the lithium-ion batteries allow for over 8 hours of operation, even with the backlight on.

Applications 

General Crack Detection

Locator 2s can be used with a wide range of probes to detect surface-breaking and sub surface cracks. Adapters are available, allowing you to use other manufacturers’ probes.

Conductivity Measurement

Locator 2s can measure the conductivity of metals. This can, among other things aid in the verification of material hardness and in the identification of materials as part of a quality control system.

Coating Thickness Measurement

This function can be used to measure non-conductive coatings such as paint and is often used as a quality control measure in the surface coating industry.

Weld Inspection

Locator 2s can be used with Hocking’s specially designed WeldScan probes to test for cracks reliably and accurately in welds.

Fastener Inspection

Metal around fasteners, such as those found on aircrafts, must be inspected regularly to ensure their material integrity. Locator 2s, coupled with the appropriate probe, can easily and quickly carry out such inspections.

Thread Inspection

Thread inspection is carried out in a range of industries, including aerospace, petrochemical, civil engineering and automotive. Locator 2s provides the ideal solution to ensure quality, safety and reliability.
