Protovale 331 Model B

Protovale 331 Model S

The Protovale 331 Model S combines all the features, flexibility, and ease of use of the Model B, plus additional functions, making it ideal for civil engineering and infrastructure inspection professionals. If you want to measure concrete thickness very precisely, the Protovale 331 Model S is a mid-range instrument designed for users seeking excellent measurement accuracy and reasonable memory capacity to record and later transfer values to a PC.

• Automatic Bar Sizing: The Protovale 331 Model S has two reinforcement bar sizing modes:
  • Autosize: for a quick estimation of bar size with display in the main measurement mode.
  • Orthogonal: a more accurate method to determine the size of unknown bars.

• Low-Coverage Mode: The sound signal only triggers when a minimum thickness is detected.
• MaxpipTM Mode: The buzzer only sounds when the probe passes over the center of a rebar, allowing for quick mapping of rebar placement.
• Min/Max Coverage Limits: Enables programming of minimum and/or maximum limits to ensure concrete thickness is within required specifications.
• Memory and Statistics: It is possible to store 1,000 individual measurements along with statistics, print them directly via a printer, or transfer them to a PC using the EDTS+ Excel Link software provided with the instrument or the CoverMaster® analysis software.

Protovale 331 Model T

The Protovale 331 Model T combines all the features of Models B and S, with an extended memory capacity of 65,000 measurements, organized into individual batches or combined grid analyses. Despite its enhanced performance, ease of use is maintained through a drop-down menu. The CoverMaster® software, included with the Model T, allows for batch design and immediate inspection. It offers two recording modes: linear and grid, with fully customizable inspection area sizes. Multiple title fields allow for detailed data management, including site and inspector information. Fully customizable inspection area sizes: Unique in its kind, the Model T allows you to define the size of your mapping grid (each square) yourself. Numerous title fields: Each batch contains multiple identification fields for simplified data management, including site name, location, measurement location, inspector and client names, as well as maximum and minimum limits and batch name. An additional field exists for any notes or instructions.

Accessories:

Telescopic Handle Kit This accessory facilitates measurements by eliminating the need for ladders or scaffolding. It also spares the operator from uncomfortable kneeling positions and allows easy inspection of bridges and floors, for example. It is compatible with the Standard or High-Precision Targeting head.

Drill Probe The Protovale series rebar locators are unmatched in precisely determining the location and orientation of the first layers of rebar and transverse bars. No other covermeter can detect successive layers of deeply embedded metal reinforcements or locate pre-tension or post-tension tendons beneath the upper reinforcement layer. When connected to the Protovale 331, the Drill Probe allows the user to locate reinforcements and ties at greater depths than any other instrument available today.Elcometer Protovale Calibration Block This calibration block allows the user to verify the accuracy of their instrument readings. It includes four different coverage values marked on the block.
