This easy to use gauge quickly and accurately locates, orientates and measures the depth of cover over reinforcement bars.

Designed to meet IP65 this rugged waterproof gauge can be used in the harshest of environments.

• Fast and accurate:
  • Locate and determine orientation of rebar quickly, easily & accurately.
• Large, easy to read backlit display:
  • For easy viewing in dark environments.
• Interchangeable search heads:
  • Select from standard search head, narrow pitch search head, deep cover search head and borehole probe.
• Single handed operation:
  • Most functions can be accessed & controlled through 4 simple keys.
• Intuitive menus in multiple languages:
  • Allows use straight out of the box.
• International bar sizes:
  • User selectable bar sizes include metric, US Bar Numbers, ASTM/Canadian and Japanese for use anywhere in the world.
• Rechargeable battery supply:
  • Battery packs can be charged inside or outside the gauge.
• Ergonomically shaped case:
  • For ease of use and comfort, with a gentle curve to fit snugly against the hip.

The Elcometer Protovale 331 Model S Covermeter includes all of the features, flexibility and ease of use of the Model B , and has additional functionality making it the gauge of choice for structural and civil engineers and surveyors alike.

Measuring concrete cover thickness with a very high level of accuracy, the Elcometer Protovale 331 Model S is an intermediate level gauge for users who want greater accuracy in measuring the depth of rebar together with a simple data storage capability for recording and downloading data at a later date.

• Automatic Rebar Sizing - the Elcometer Protovale 331 Model S has two modes of rebar estimation:
• Autosize - a quick estimation of the bar size, displayed in the main measurement mode; and
• Orthogonal - a more accurate method to determine the size of unknown bars.
• Under Cover Mode - the gauge's buzzer only sounds when a minimum cover has been detected.
• Maxpip Mode - the buzzer only sounds when the search head has passed the centre of the rebar, ideal for fast identification of the layout of the rebar.
• Min / Max Cover Limits - program in minimum and/or maximum cover thickness values to monitor whether depth of cover is within specification.
• Corrosion check:
  • Check for potential corrosion of rebar using the same gauge.
• Large memory:
  • Holds up to 10 linear batches of 1,000 readings in each batch.
• Large, easy to read backlit display:
  • Graphical display clearly shows statistics, batches, graph plots and numerical readings.
• Interchangeable search heads and Half-Cell kits:
  • Select from standard search head, narrow pitch search head, deep cover search head, borehole probe, Copper Half-Cell Kit and Silver Half-Cell Kit.
• Powerful Covermaster® Software:
  • Ultimate data management tool to store cover & Half-Cell readings and produce professional reports quickly and easily.

Incorporating all the features and functionality of the Model B and Model S Covermeters, the Model T comes with the additional ability to store in excess of 240,000 readings in either individual batches or multiple spreadsheet (grid) style batch surveys.

• Linear and Grid data logging - the Elcometer Protovale 331 Model T has two data logging methods:
• Linear - where data is simply stored in a batch, one reading after another; and
• Grid - where data is stored in a spreadsheet format each cell relating to a survey square marked out on the concrete.
• User definable "pitch scales" - unlike other covermeters, the size of each survey square can be defined by the user.
• Wide range of batch headers - each batch has a wide range of identification fields for easy data management, these include:
• Site Name, Site Location, Measurement Location, Engineer's Name, Customer's Name, together with max & min cover limits and batch name. There is an additional field to add a survey note or instruction.

The range of Protovale by Elcometer Concrete Covermeters are unequalled at finding the precise location and orientation of the first layers of reinforcing bars (rebars) with the transverse bar tied to it.

No covermeter will find subsequent layers of steel reinforcement deep within the concrete. Nor can they locate pre-stressing or post tensioning tendons underneath the top reinforcement.

When the Elcometer Borehole Probe is connected to the Elcometer Protovale 331 the user can now locate rebar and tendon ducts at greater depths than any other covermeter on the market today.

Designed to meet most of your measurement requirements.

Accurately measures the cover thickness when the gaps between each of the rebars (pitch) are close together.

The ideal search head for accurately measuring rebars that are deep within the structure.

The ability to detect high tensile steel and three grades of stainless steel (304, 316 and Duplex). For use with Model THD only.
