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

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.

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)

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

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.

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.

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.

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.

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.
