Concrete Hardness Tester
W-M-350
The W-M-350 Recording Test Hammer gives you the same quality as the W-M-250 but with the added feature of a built-in automatic chart recorder. Every test you take is automatically recorded as a bar chart on a paper strip.This creates a field record to verify your findings.In addi- tion to this paper record,you can see each test as it happens through the large easy to read window

Ultra-sonic Test System
V-Meter
The V-Meter is an advanced ultrasonic, pulse-velocity test system widely used for quality control and evaluation of concrete structures. It can identify non-homogeneous conditions such as voids, cracks, honeycombs and frozen concrete.

Rebar Corrosion Rate Determination System
Gecor 6
Measures the rate of corrosion and other parameters of rebars. The Gecor 6 utilizes the polarization resistance technique to establish the corrosion rate. This is a quantitative measure of the amount of steel oxidizing at the time of measurement. Up to 100 readings can be stored in memory for later uploading to a Personal Computer.

Aquameter
T-M-160
he James Instruments? Aquameter MK II utilizes the latest electronic technology to measure the quantity of water within its sensing field. The T-M-160 using a high frequency capacitive sensor, samples a large volume of material, approximately 460 mm x 670 mm x 25 mm (1 13/16? x 2 5/8? x 1?), instantaneously.

Ultrasonic Transducers
Low frequency transducers for ultrasonic testing of concrete and other course grained materials. Shear Wave transducers (pictured above) are used in combination with compressional wave transducers to calculate Poisson's Ratio. The line of general-purpose compressional wave transducers feature robust PZT elements in stainless steel.

Determines Presence of Carbonation on Concrete Samples
Carbo Detect System™
Carbo Detect is a simple colored dye field test for detecting carbonation. The single reagent is sprayed on the surface to be checked. The reagent will change to pink in uncarbonated concrete and remain colorless when sprayed on carbonated concrete.

Testing Tensile Strength of Overlays, and Overlayments
James Bond Test ™ MK III
The James Pull Off Adhesion/Bond Tester measures the pull force used to pull a 2? or 3? disc away from the material being tested. This pressure is displayed on a precision gauge and can be related directly to the strength of the adhesion to the surface being tested.

Concrete Hardness Tester
W-M-250
The W-M-250 Manual Test 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)

Resistivity Meter for Concrete
Ohmcorr Test System™
OhmCorr has two probes spaced 1.97" (5cm) apart which are placed in holes drilled to a depth of 3/8th" (8mm) and filled with conductive gel. The direct digital read-out of resistivity is displayed on the LCD when the control switch is activated. OhmCorr and CorMap, when used together, provide an economical and sound diagnostic system of corrosion in reinforced concrete.

Resonant Frequency Testing
E-Meter MK II™
Determines resonant frequencies of the three modes of vibration. Material characteristics such as Youngs Modulus of Elasticity, Modulus of Rigidity, Poissons Ratio and Damping Constant can be calculated. Frequencies are automatically scanned in one of four ranges. The system can determine flexural resonance of concrete under accelerated freezing and thawing cycles and aggressive environments.
