Elcometer 331 Mk2 Basic BH Model Concrete Cover Meters
Product Description
An easy to use gauge that quickly and accurately locates/orientates reinforcement bars in concrete and measures the depth
of cover over the rebar.
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/buttons
Accurate
- Locate and determine orientation of rebar quickly, easily & accurately
- Up to 240,000 readings can be stored on the gauge for detailed reporting
- Memory and data logging with data output to PC or direct to printer
- Graph Plotting allows an immediate visual indication of results
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
Tough
- Specifically designed for use on-site
- Rugged, waterproof IP65 case provides protection against the elements
- Backlit screen for viewing in dark environments
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 |
Half-Cell Mode • Typical Screen View | |
Graphics Plot Mod • eHalf-Cell Mode – the gauge indicates the areas with the most potential for corrosion | |
Threshold View • Ideal method for a simple pass or fail analysis | |
Autosizing and Orthogonal Function • Autosizing automatically estimates the size of rebar and the depth of cover |
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
