Moisture Master
T-M-170
The James Instruments Moisture Master utilizes the latest electronic technology to measure the quantity of water within its sensing field. The unit has two modes of operation the pin mode, and search mode. In the pin mode, two pins are pushed into the material and a high frequency field is created between these two pins.

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.

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.

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.

Measures Wide Range of Anchor Strengths
Anchor Test System
Two models, each with two different gauge capabilities enable precision readings over a wide range of applications - from light to heavy duty loads. The standard system has a pull stroke of two inches with an option to extend to four inches. The longer pull stroke allows for complete extraction of most fixings in one simple operation. A load diffusion bridge and pyramid are available to keep reaction loads away from the anchor point.

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.
