Product
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.

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)

Product
Trident
T-T-90
-
The Trident T-T-90 utilizes the latest microwave and microprocessor technology to measure moisture content in various fine and coarse-grained materials. The prongs of the probe are inserted into the material to be tested and the percentage of moisture content is instantaneously shown on the easy to read display.

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
Ultrapulse
-
The James Ultrapulse is ideally suited for the testing of ceramic materials, refractories, plastics and laminates. Ultrasonic velocity measurement permits accurate and repeatable calculation of modulus of electricity, bulk density and the detection of cracks. Stored data can be uploaded to a PC with the optional hand-held terminal. The Ultrapulse can be used with a wide range of ultrasonic stansducers for all of your ceramic testing needs.

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
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.

Product
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.

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.

Product
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.

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.

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.
