Moisture/Density Gauge EZ Series
The New EZ-2’s versatility allows it to measure density through
direct transmission, backscatter, thin lift and trench modes, as
well as providing moisture determinations.
CodeMH320
Other Standards ASTM D6938, ASTM D2950, ASTM C1040, AASHTO T310, BS 1377-9: Clause 2.5
Easy to operate, easy to power and easy to service. The EZ gauge features a menu-driven control panel with easy-to-use, built-in test routines and auto features, making testing a quick and accurate operation. It also features our innovative trigger release handle that eliminates pinched fingers while providing smooth operation.
The EZ gauge provides a single gauge solution to density and moisture measurements.
The EZ’s versatility allows it to measure density through direct transmission and backscatter modes, as well as including thin lift and trench modes, as well as moisture determinations. The gauge uses an advanced micro-processor-based technology to provide highly-accurate measurements of density and moisture that are automatically computed for direct readouts of wet density, dry density, moisture content, percent of moisture, percent of compaction (Proctor or Marshall), void ratio and air voids.
ASTM D6938 D2950, C1040
AASHTO T310.
The gauge is calibrated by the Five-block calibration method.
• Menu-driven operation—direct readings in engineering units
• AA batteries eliminate charging—6-12 month battery life
• Easy operation handle with positive latch
• Modular design, simplifies repairs
• Automatic depth sensor
The EZ gauge features a menu-driven control panel with easy-to-use, built-in test routines and auto features, making testing a quick and accurate operation.
The EZ is powered by six standard AA alkaline batteries, which provide up to 2000 hrs of service. No chargers are needed and you can buy batteries almost anywhere.
The EZ gauge also uses a modular design, which allows it to be serviced in the field, if ever necessary. With this gauge, you don’t have to send it back to the factory for repairs, we’ll send you the necessary components and walk you through any repair procedure.

Electrical Moisture / Density Gauge
Nuclear-free gauge to ASTM D7698
The Electrical Moisture/Density Gauge is a nuclear-free alternative for determining the moisture and density of compacted soils used in road beds and foundations. It is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety.
Its user-friendly, step-by-step menu guides the user through each step of the testing procedure and cautions the user when values do not correspond to established curves for the material being tested.
Easy-to-use, it can be used as a construction aid to monitor day-to-day compaction operations by providing performance and measurement results highly comparable to those achieved with traditional methods, including the nuclear gauge and/or a sand-cone and oven moisture test combination.
When conducting a test, the Electrical Moisture/Density Gauge measures and displays the results for wet and dry density, gravimetric moisture content and percent compaction.
For contractors the advantages are:
The Electrical Moisture/Density Gauge measures the electrical dielectric properties and moisture levels of compacted soil using high, radio frequency traveling between darts driven into the soil being tested. The dart's depth of penetration positively determines the depth of measurement.
Darts are available in 4", 6", 8", 10" and 12" lengths. In addition, the darts have been designed with a taper, which ensures a continual positive contact with the soil for accurate measurements.

Strain Gauge Based Submersible Triaxial Load Cell
This series of submersible triaxial load cells has been designed for measuring compressive loads from 1kN to 50kN. The products can be fitted into new or existing triaxial cells with a diameter up to100mm.
The design features an internal pressure compensation system that eliminates zero offset changes when the load cell is subjected to external pressure changes. Being insensitive to cell confining pressure, the load cell can be used inside the triaxial cell.
As the load is measured within the cell it eliminates the effects of piston friction.
The use of specially selected heat treated stainless steel and precision strain gauges ensure optimum performance and
excellent long term stability.

These WiFi loggers utilise the latest WiFi wireless technology. The loggers are a battery powered, cost-effective, temperature monitoring system that remotely records the temperature of appliances and buildings. Each logger transmits the recorded data to a WiFi router connected to the internet which can be accessed and viewed from a PC, laptop or tablet anywhere in the world.
The loggers have a range limited to the specification of the users WiFi router. Each logger has a intuitive LCD displaying temperature, WiFi connection status, max/min recorded temperatures, alarm status and battery life.
At programmable intervals, the loggers will record temperature from both sensors, recording up to a maximum of 18000 readings (9000 from each sensor). Each logger incorporates a red and green LED. The flashing green LED indicates that the logger is active/logging and the flashing red LED indicates that your customised preset alarms have been exceeded. Each unit is supplied with a USB lead.
