      331-short-description-2

      Reliable

      • Stainless Steel rebars can be located by the THD Model
      • Battery packs can be charged in the unit or externally. Additional batteries allow continued use

      A range of fully interchangeable search heads, borehole probes and half-cell probes are available to suit the requirements without the need to return your gauge to Elcometer.

      Changing from one search head to another is quick and easy; simply switch off the Covermeter, swap search heads, switch on again and zero the Covermeter.

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

      User Friendly

      • Easy to transport and store
      • Ergonomically shaped case for comfort
      • Single handed operation: All functions can be accessed & controlled through 4 simple keys/button

      Efficient

      • Rebar locator, concrete covermeter and half-cell measurement all available in a single gauge - (selected models)
      • Intuitive menus enable each gauge to be used straight from the box

      Powerful

      • Links to Covermaster™ software
      • Ultimate data management tool to store cover & half cell readings and produce professional reports
      • On Screen graphic display provides visual assessment of readings allowing identification of areas of low concrete cover or potential areas of corrosion

      Cover Display Screen

      Alternative / Typical Data Review Screen View

      • Backlit screens for use in dark conditions
      • Easy to use menus, in multiple languages to enable access to all data needed whilst on site without constant reference to the instruction book
      • The alternative view shows the typical display when using the deep cover search head
      • Bar size and depth of cover can be input manually to suit specific requirements
      • Typical data review screen clearly displays where readings are below or above a user specified tolerance, where reading has not been taken
      • Units of measurement can be displayed in mm or inches for cover, or mV for Half-Cell

            Half-Cell Mode

            Typical Screen View

            • Elcometer 331 Model BH/SH/TH/THD can read both Cover and Half-Cell Values
            • Elcometer 331 Model B can read Cover Values only
            • Data logging information displayed on the screen
            • Menu soft keys are visible in Elcometer 331 Model SH and TH

            Graphics Plot Mode

            • Half-Cell Mode - the gauge indicates the areas with the most potential for corrosion
            • Covermeter mode - the gauge indicates the depth of cover
            • Black indicates most potential for corrosion
            • White indicates the least potential for corrosion with varying greyscale shade in between
            • Zoom feature allows the user to take a closer look at different areas that are of interest

            Threshold View

            • An Ideal method for a simple pass or fail analysis
            • Once the threshold value has been set, anything before the value is shown in black, while anything over the value is shown in white

            331-screen-7_1

            Autosizing and Orthogonal Function

            • Autosizing automatically estimates the size of rebar and the depth of cover
            • If this estimated figure differs greatly from your expected rebar size or you do not know the expected rebar size, the orthogonal size function provides an accurate measurement of bar size
            • The step by step directions for orthogonal function on the covermeter make the accurate sizing of bars quick and easy

            Data Logging Feature

            Simple Data Management on the Elcometer 331 Models SH, TH and THD

            • The Elcometer 331 Model SH can store up to 10 batches of 1,000 cover or half-cell readings, with batch statistics, ready for evaluation and report generation using Covermaster™ software package
            • The Elcometer 331 TH and THD models have user definable memory batches with either linear or grid batch data logging modes. (Linear batching is where data is stored in a batch one reading after another)
            • Grid batches allow data to be stored in a 'spreadsheet format' with each cell relating to the survey area typically mapped out on the structure prior to inspection. The grid batch feature facilitates fast surveying for both cover and half-cell readings. Problem areas that do not fall within specification can be immediately identified and marked directly on the concrete
            • Cover and half-cell readings can be recorded and 'overlaid' in each grid location

            Powerful Statistics Feature

            • Continually calculates and displays the statistical analysis of readings as they are taken. So, while the covermeter is in use, you are always informed and know exactly how your site survey is progressing
            • Statistics values are also calculated for the readings within each batch and these values are stored in the batch along with all individual readings

        Cover Display Screen

        Alternative / Typical Data Review Screen View

        • Backlit screens for use in dark conditions
        • Easy to use menus, in multiple languages to enable access to all data needed whilst on site without constant reference to the instruction book
        • The alternative view shows the typical display when using the deep cover search head
        • Bar size and depth of cover can be input manually to suit specific requirements
        • Typical data review screen clearly displays where readings are below or above a user specified tolerance, where reading has not been taken
        • Units of measurement can be displayed in mm or inches for cover, or mV for Half-Cell
              331-screen-3_1

              Half-Cell Mode

              Typical Screen View

              • Elcometer 331 Model BH/SH/TH/THD can read both Cover and Half-Cell Values
              • Elcometer 331 Model B can read Cover Values only
              • Data logging information displayed on the screen
              • Menu soft keys are visible in Elcometer 331 Model SH and TH

              Graphics Plot Mode

              • Half-Cell Mode - the gauge indicates the areas with the most potential for corrosion
              • Covermeter mode - the gauge indicates the depth of cover
              • Black indicates most potential for corrosion
              • White indicates the least potential for corrosion with varying greyscale shade in between
              • Zoom feature allows the user to take a closer look at different areas that are of interest

              Threshold View

              • An Ideal method for a simple pass or fail analysis
              • Once the threshold value has been set, anything before the value is shown in black, while anything over the value is shown in white

              331-screen-7_1

              Autosizing and Orthogonal Function

              • Autosizing automatically estimates the size of rebar and the depth of cover
              • If this estimated figure differs greatly from your expected rebar size or you do not know the expected rebar size, the orthogonal size function provides an accurate measurement of bar size
              • The step by step directions for orthogonal function on the covermeter make the accurate sizing of bars quick and easy

              Data Logging Feature

              Simple Data Management on the Elcometer 331 Models SH, TH and THD

              • The Elcometer 331 Model SH can store up to 10 batches of 1,000 cover or half-cell readings, with batch statistics, ready for evaluation and report generation using Covermaster™ software package
              • The Elcometer 331 TH and THD models have user definable memory batches with either linear or grid batch data logging modes. (Linear batching is where data is stored in a batch one reading after another)
              • Grid batches allow data to be stored in a 'spreadsheet format' with each cell relating to the survey area typically mapped out on the structure prior to inspection. The grid batch feature facilitates fast surveying for both cover and half-cell readings. Problem areas that do not fall within specification can be immediately identified and marked directly on the concrete
              • Cover and half-cell readings can be recorded and 'overlaid' in each grid location

              Powerful Statistics Feature

              • Continually calculates and displays the statistical analysis of readings as they are taken. So, while the covermeter is in use, you are always informed and know exactly how your site survey is progressing
              • Statistics values are also calculated for the readings within each batch and these values are stored in the batch along with all individual readings
