A simple and robust system for the measurement and recording of water wave profiles, which uses the principle of measuring the electrical conductivity between two parallel wires. Each probe consists of a pair of stainless steel wires which dip into the water waves. The electrical conductivity between them is measured, and is linearly related to their depth of immersion hence to wave height. The method is free of meniscus and `wetting effects.
The system is available in 1, 2 or 3 channel form and can display data by high speed recorder or input to a data logger. Alternative lengths of probe are 300mm or 500mm.
The probe consists of two 1.5mm diameter stainless steel wires spaced 12.5mm apart and 300mm long or 500mm long as required. Each probe is connected to its own wave monitor module in the electronic console by a twin core flexible cable 10m long. The distance between the console and probe may be increased up to 100m using commonly available low current cables.
Energization is conducted by means of an audio frequency drive signal which avoids all polarization effects at the wire interface. The signal is balanced relative to earth, to render the system immune to common mode voltages between the water and instrument earth. The frequency can be altered to permit two or more sensors to operate in close proximity without mutual interference.
The power supply module and appropriate number of wave monitor modules are mounted in a console, finished in matte textured blue paint and fitted with four rubber feet and carrying handle.
The result is a system giving high dynamic accuracy over a wide range of wave heights and frequencies.

Welding Technology Learning System consists of a workstation with a self-contained down-draft table and angle grinder, storage station, gas metal arc welder, weld test fixture, tools and fixtures, safety gear, student curriculum and teachers assessment guide.
The Welding Technology Learning System teaches how to safely create an array of high quality weld types. Welding plays a critical role throughout our economy. It is central to many industries including manufacturing, construction, and aerospace to name only a few. Welding is a blend of both art and science, joined together to create enduring bonds that allow us to create structures and machines on a scale impossible to achieve without it. The Welding Technology Learning System is mobile with both the workstation and storage unit designed for classroom use.
Features:
Mobile Technology Workstation with Vise
Magnetic Stainless Steel Top Workstation
Turnkey Storage Station.
