Product
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.

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)

Testing Released Water Vapor
Humiditest™ Complete System
-
The James Instruments Humitest System allows the concrete practitioner to monitor and ensure that a new structure is dry enough to proceed with the next phase of construction. This is especially critical for concrete structures requiring a coating, carpeting or similar floor or covering treatment. Installing such treatments before the concrete is sufficiently dry will typically cause expensive failures in the covering treatment. The only accurate way to ensure that the concrete is sufficiently dry enough to safely avoid expensive re-work is via a bore hole humidity test system, such as the Humitest System

Chloride Test System
C-CL-2000
-
The C-CL-2000 produces results on-site, within minutes that are accurate and comparable to expensive laboratory tests. It measures the electrochemical reaction of a weighted sample placed in an extraction liquid. It automatically shows a temperature compensated reading of percent of chlorides on its digital display. A wide range - from 0.002 to 2% chloride by weight - is covered.

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.

Product
Concrete Hardness Tester
W-C-7312
-
It is recommended that calibration of the test hammers be checked regularly usually after about 2000 strokes.The James Calibration Anvil (W-C-7312) has been designed for just that purpose.

Product
Hand Held Microwave Moisture MeterFor Water/Cement Ratios of Fresh Concrete
Cementometer
-
The James Cementometer represents a break-through in modern moisture measurement technology. By utilizing the latest microwave and microprocessor science, the Cementometer can determine the moisture content of freshly mixed cement, concrete, and mortar. Simply insert the prongs of the probe into the material to be measured and instantaneously the water cement ratio is shown on the easy to read display.

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.

Product
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.

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.

Tempurature Monitoring System
IQT-Meter
-
A flexible and economical temperature monitoring system, the IQT features extensive memory and graphic display of temperature history. Similar to the IQM, the IQT System offers software for uploading the temperature data to a P.C. through its serial port. The temperature history can then be displayed with respect to time

Product
Sand or Aggregate Moisture Testing
Aggrameter®
-
Determines the water content in construction materials like sand and gravel to ensure proper concrete mix design, affecting strength and workability.

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.

Air and Water Permeability in Concrete Both At and Below the Surface
Poroscope
-
Poroscope Plus measures the time it takes for air to flow into a known volume of a sealed, evacuated chamber in the concrete. While the vacuum reduces from -55 Kpa to -50 Kpa, a measure of air permeability is determined. For water permeability, Poroscope Plus uses the same chamber filled with water, and measures the total time in seconds for a volume of 0.01 ml of water to escape.
