Kolectric MC8022 Covermeter

The Kolectric 8020 Micro Covermeter is a compact, industry-standard pulse-induction instrument built for structural engineers, building inspectors, and concrete testing specialists. Designed to quickly map structural reinforcement bars within hardened concrete, it provides precise depth readings up to 100mm, allowing operators to verify build compliance or safely locate clear drilling paths. Its highly responsive sensor probe accurately discriminates between closely spaced reinforcement layouts, minimizing the risk of costly rebar strikes during coring or structural alterations.

This rugged handheld device combines a clear dual-scale analog meter with a real-time digital display for instantaneous visual feedback, supplemented by an adjustable acoustic signal that peaks directly over the rebar center line. To maximize versatility across different site configurations, it includes a direct-reading bar size compensator dial that allows users to calibrate the gauge specifically to standard structural bar diameters. Housed in a durable protective casing with heavy-duty control dials, this instrument offers simple, repeatable field calibration and excellent long-term structural reliability.

Precision Pulse-Induction Sensor: Delivers accurate rebar location and depth measurement down to 100mm, ensuring dependable non-destructive testing through dense concrete structures.
Bar Size Compensation Dial: Features an integrated mechanical dial to easily adjust the instrument for varying standard rebar diameters, ensuring precise true-cover depth readings.
Audio-Visual Target Detection: Combines a highly responsive dual-scale analog needle meter with an adjustable acoustic speaker that intensifies directly over the rebar centerline.
Compact Handheld Ergonomics: Built into a lightweight, durable field chassis with intuitive tactile controls, allowing for effortless single-operator surveying across walls and ceilings.

FAQs

What is the maximum depth range of the Kolectric 8020?

The instrument can accurately detect reinforcement bars and measure concrete cover depths up to approximately 100mm under standard operational conditions.

Is this instrument available for short-term hire or just direct purchase?

Yes, we offer flexible hire options ranging from a few days to multi-week rentals, allowing you to scale your equipment fleet to match project durations without capital expenditure.

How does the covermeter indicate when it is directly over a rebar?

It utilizes an integrated audio-visual system where the analog meter needle peaks and an acoustic audio tone reaches its highest frequency directly above the center line of the bar.

Can this device identify the size of the buried reinforcement bar?

Yes, by utilizing the built-in bar size compensation dial in conjunction with a simple close-up measurement technique, you can determine standard structural bar diameters.

Does the 8020 require complex programming before use?

No, it is designed for rapid deployment, featuring simple manual zero-calibration dials that allow operators to adjust the unit for immediate site use in seconds.

Is this instrument suitable for checking concrete before diamond coring?

Absolutely, it is widely used by drilling and coring contractors to locate clear paths through reinforcement layouts, saving expensive diamond bits from damage.

What power source does the Kolectric 8020 utilize?

The unit operates efficiently on standard, easily replaceable commercial batteries, providing extensive runtime for prolonged structural surveys.

Can it detect non-ferrous metals like copper or stainless steel?

The pulse-induction system is optimised specifically for magnetic ferrous metals like standard steel reinforcement rebar, which provides the strongest signal return.

Is the search probe separate from the main display unit?

Yes, it utilizes a handheld search probe connected via a flexible cable, allowing you to easily maneuver the sensor over rough concrete surfaces, corners, and ceilings.

How does the bar size compensation dial improve accuracy?

Because different bar thicknesses affect the magnetic field differently, setting the dial to the known bar diameter corrects the depth scale to read the exact true concrete cover.
