Bar Diameter:	Cover:	Minimum Spacing:
16mm	60 mm	70mm
16mm	100 mm	110mm
25mm	130 mm	150mm

DATA LOGGING CAPABILITY
The logging capacity is 10000 bits of information comprising:

• Cover measurement
• Bar size
• Date
• Time
• Log Number

The PC application communicates with the 8020 via a serial port and enables the downloading directly into a Microsoft Excel spreadsheet format (*.csv file).
This will include the facility to download a selected range of logged data "points" such that only the required data is transferred to the spreadsheet.
This program is simple to install and has been tested on Windows 2000, ME and XP.

Using high-powered processors in conjunction with pulse induction search technology, automatic bar diameter determination within the parameters defined below enables very precise depth readings and bar orientation to be obtained even where there is the need to discriminate between bars on close centres.
 
Several Menu and Set-up screens are available to tailor the 8020 to your local requirements, and the unit remembers these settings at switch on until modified, even after power-down for battery conservation.

Battery life is shown on screen but an additional visual indication is given when to continue work might compromise stored data, and that re-charging is essential.

A typical operating screen is shown below.

8020 Series
Technical Specifications

On/Off-Function switch on keypad selects Menus as required.

The screen appearing immediately after the Cover depth screen shown above is for Bar Sizing.

A further screen is available for examining data that has been logged from the K9 probe.

This probe also has an LED for assisting in finding the top dead centre position of bars as the probe is swept across the surface.

Determination of the position of direction of axis of a reinforcing bar is made by moving the search head on the surface of the structure. Defining the position and direction of the various reinforcement bars produces a precise picture of the grouping of entire reinforcing systems in various parts of a structure and after familiarisation with the instrument it is possible to define bar ends, enlargement, hooks and ties.

The Micro Covermeter is supplied complete with Mini Probe search head, carrying case, weatherproof instrument cover, spare batteries as well as the fitted set, bar sizing spacers and instruction manual.

PROBA 3D
MICRO COVERMETER

The Worlds first microprocessor controlled reinforcement bar locator
just became
The World's most compact, data logging, reinforcement bar locator

The Proba 3D Micro Covermeter is a fully specified, hand-held, data logging reinforcement bar locator, weighing less than 400g. With a choice of probes, the unit offers the greatest flexibility for bar discrimination and depth of cover. Fully integrated software and user programmable features, make this a truly worldwide instrument,

Standard Features with Mini Probe

Scanning depth up to 120mm

Accuracy = / > BS I88I:204

Logged data output direct to spreadsheet

Can be used on concrete pipe and spiral mesh

Bar alignment capability with visual / audio tone

Quickscan audio feature to check for correct cover over rebar

One square metre can be scanned in less than one minute

 Extra Features with Maxi Probe

 Scanning depth up to 360mm

Out performs all known competition

Technical Data

The Proba 3D Micro Covermeter quickly identifies the position and direction of the reinforcing bars then accurately measures and records their cover and diameter to BS I88I:204. The compact screen allows full information display, including user instructional information.

Weighing less than 400g, the Proba 3D will not make heavy work out of a long survey, but in case you need a hands-free operation, there is a high visibility comfort pouch supplied standard with the kit.

Environmentally sealed to IP65 and with on-board battery and charging, this unit will not let you down whatever the weather.

COVERMETER - 8010
Technical Specifications
 

It has been shown that pulse induction technology cannot achieve detection of deeply embedded reinforcement bars and so search and receive coil techniques are used with the Depth probe to achieve results down to a world's best 360mm of cover.

Where more precise, fully automatic, bar sizing and, by extension, depth determination and bar discrimination is required, then the 8020 model should be employed. Several menu and set-up screens are available to tailor the 8010 to your local requirements, and the unit remembers these settings at switch on until modified, even after power-down for battery conservation.

Battery life is shown on screen but an additional indication is given when to continue work might compromise stored data and that re-charging is essential.

A typical operating screen is shown below:

On-Off function switch on keypad selects menus as required.

The screen appearing after the Cover depth screen is for the manual bar size estimation routine.

Two measurements are taken, one after insertion of a spacer block and then the instrument calculates the bar size and updates the working memory.
