Product
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

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
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.

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)

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.

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.

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.

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.

Product
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.

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
