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.

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.

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.

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

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.

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

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.

Concrete Measuring and Monitoring System
IQM-Meter
-
Designed specifically for monitoring and analyzing fresh concrete, the IQM Module is programmed with the required Equivalent Age of the concrete under test. Once this preset maturity number is reached, a visual indicator will flash continuously, providing an effective, automatic indication that the concrete has reached the desired level of maturity.

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.

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.

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.
