The M-250 Manual Concrete Rebound Hammer is the traditional instrument used for the non-destructive testing of hardened concrete. This easy-to-use instrument provides a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure. The minimum verifiable strength is 1400 PSI (10 MPa).

WP-2000 Windsor Pin System
Measures the compressive strength of concrete, mortar and brick in-situ, quickly, accurately. A non-explosive instrument, the Windsor Pin System uses a spring-loaded device to drive a steel pin into the concrete or mortar. The depth of penetration of the needle correlates to the compressive strength of the material under test. A removable chuck and a small pin size facilitate the testing of mortar joints; this is the only system for testing the in-place strength of brick mortar joints. Conforms to ASTM C-803.
The Mini R-Meter is a completely digital, rugged hand held field instrument for finding the location, depth, and size of reinforcement bars in place. Built in memory can store over 150 individual data points for later processing.
Features & Benefits: ♦ Eddy current design for greater accuracy. ♦ Single sensor for all depth ranges. ♦ Daylight visible display ♦ Locates up to 8 (200mm) ♦ Economical
C-3000 Digital Rebar Locator
R-Meter MK III is the digital version of a classic rebar locator, rebar finder which enables the user to locate reinforcement bars and also determine rebar location and rebar size. The R-Meter MK III rebar locator is also capable of locating non ferrous metals as well.
Features & Benefits: ♦ Eddy current sensor design for greater accuracy. ♦ Single sensor for all depth ranges. ♦ Locates rebar, post tension cable, conduit, and copper pipe. ♦ Determine bar size up to 4.5 (115 mm) deep. ♦ Daylight visible display. ♦ Rugged and splash resistant case. ♦ Optional scan cart. ♦ Locates up to 8 (200 mm) deep.
Maturity Meters 4-Channel Maturity Meter Set (H-2680) Rechargeable 4-Channel Maturity Meter Set (H-2682)
Maturity Meters provide a predictable strength determination of cast-in-place concrete based on ASTM Standard C1074-98 (Estimating Concrete Strength by the Maturity Meter Method).
Rapid Chloride Permeability Control Panel HM-722A 4-Cell Model HM-724 8-Cell Model
It is often necessary to evaluate chloride permeability characteristics of concrete in bridges and other structures. Now the electronic technology is available to evaluate slices of cores taken from such sources using a 6-hr. laboratory procedure. By testing slices from laboratory cylinders, the method is also suitable for evaluation of materials and/or additives for mix design of HPC or other concretes. Current flow with time is measured while a 4" diameter, 2" thick specimen slice is subjected to a regulated 60V DC potential across ends. The negative end is exposed to 3% sodium chloride solution, and the positive end to 0.3N sodium hydroxide solution. The Rapid Chloride Permeability test Instrument automates the integration of current relative to time to determine coulombs as a measure of chloride permeability.
Models are available to test four (HM-722A), or eight (HM-724) specimens simultaneously. Test voltage, test time, current for each specimen and coulombs for each specimen are continuously displayed. Printouts of the above data are automatically activated every 30 minutes or at a different user selectable rate. The printout can also be manually activated at any time by switch and are directed to the internal printer. Tests are automatically terminated at 360 minutes. Current range is 0-1 amp DC per core. The Rapid Chloride Permeability Units have a wide range voltage supply capability of 30 to 60 volts DC. Instrument cabinets measure 19x17x7", WxHxD. ASTM C1202 & AASHTO T277
