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

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.

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.

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.
