Key Features
Elcometer 331 Covermeters & Half-Cell Meters
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
- eHalf-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
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
