Pressure Gauges & Instrumentation
GNW supplies pressure and vacuum instrumentation for industrial, process, test and general-purpose applications.
Our range includes general-purpose, glycerine-filled, all-stainless-steel, low-pressure, test and digital pressure gauges, together with pressure transmitters, transducers, data loggers and accessories. Different pressure ranges, dial sizes, case materials and bottom or rear connections are available.
We can also provide technical selection advice, pressure-gauge calibration and support with specialist requirements.
Industrial Weighing Equipment
GNW supplies industrial weighing components for new systems, equipment upgrades and replacement applications.
Our range includes single-point, shear-beam, bending-beam, tension, compression, column and double-shear-beam load cells. We also supply weight indicators, transmitters, digitisers, remote displays, junction boxes and load-cell mounting assemblies, with communication options for integration into industrial control and automation systems.
Equipment is available for platform, tank, silo, hopper, batching and process-weighing applications. GNW can help match the load cells, mounting hardware, instrumentation and outputs required for a complete and reliable weighing system.
Hardness Testing Equipment
GNW supplies portable and bench-mounted hardness testing equipment for production inspection, quality control, engineering and material assessment.
Our Sauter range includes analogue and digital Shore hardness testers for materials such as rubber, plastics and elastomers, together with Leeb rebound and UCI hardness testers for suitable metals and components.
Test blocks, impact sensors, support rings, test stands and other accessories are also available to support repeatable measurements. GNW can help you select the appropriate testing method, hardness scale, measuring range and accessories for your application.
Scales & Balances
GNW supplies scales and balances for laboratory, medical, educational, commercial and industrial applications.
Our range includes analytical and precision balances, moisture analysers, bench scales, counting scales, platform and floor scales, medical scales, price-computing scales and test weights. Options are available with different capacities, graduations, platform sizes and levels of environmental protection.
We can help you select suitable weighing equipment and provide ongoing calibration, servicing and technical support.
Measuring & Tool Room
GNW supplies measuring and test instruments for manufacturing, engineering, maintenance, inspection and quality-control applications.
Our range includes calipers, micrometers, dial indicators and gauges for dimensional measurement, alongside digital force gauges, torque gauges and transducers, ultrasonic thickness gauges, coating thickness meters and colour spectrometers.
With different measuring ranges, resolutions, probes and configurations available, we can help you select suitable equipment for component inspection, material testing and production measurement. Calibration options and technical support are also available.
Calibration Equipment
GNW supplies calibration equipment for checking pressure, temperature and process instrumentation in laboratories, workshops and industrial environments.
Our online range includes digital reference pressure gauges, absolute-pressure gauges, pneumatic and hydraulic test pumps, pressure manifolds and accessories. We can also supply analogue test gauges, pressure comparators, deadweight testers, process and temperature calibrators, signal simulators and dry-block temperature calibrators by quotation.
For specialist applications, GNW can design and manufacture bespoke calibration equipment and complete test systems. Our team can help determine the required pressure or temperature range, accuracy, connections and control method.
Temperature Instrumentation
GNW supplies temperature-measuring and monitoring equipment for industrial, laboratory, food-production, HVAC and maintenance applications.
Our range includes digital thermometers, analogue dial thermometers, handheld thermometers and infrared non-contact thermometers. We also supply and manufacture thermocouples, RTD sensors, thermowells, temperature controllers, indicators, recorders and data loggers.
Different temperature ranges, probe styles, sensor types and mounting arrangements are available. GNW can provide technical selection advice, custom-built temperature sensors and calibration support.
Control Panels & Automated Test Stations
GNW designs and manufactures bespoke control panels and automated test stations for industrial processes, production lines and quality-control applications.
Our systems can integrate pressure, temperature, flow, level and weighing instrumentation with automated controls, alarms, operator displays and data logging. Applications include leak and burst testing, checkweighing, batching, process control and repeatable pass-or-fail testing.
Each system is designed around the required process, instruments, operating environment and data outputs. GNW can assist from the initial design consultation through to manufacture, installation and ongoing technical support.
Tank Contents & Level Equipment
GNW supplies and manufactures tank contents and level equipment for monitoring liquids stored in industrial, commercial and process tanks.
Our range includes digital tank-monitoring systems, hydrostatic contents gauges, pump-to-read gauges, sight gauges, level switches, sensors and high- or low-level alarms. Solutions are available for simple local indication or connection to building-management, process-control and remote-monitoring systems.
We can help specify equipment around the tank dimensions, stored liquid, required output, installation arrangement and operating environment.
Flow Meters & Flow Switches
GNW supplies flow meters and flow switches for measuring, monitoring and controlling the movement of liquids and gases through industrial and process pipework.
Our range includes variable-area flow meters, batching meters, magnetic, oval-gear, positive-displacement, ultrasonic and vortex flow meters, water meters and flow switches. Options are available for local indication, totalisation, alarm switching and transmission to remote displays or control systems.
We can help select suitable equipment based on the medium, flow range, pipe size, pressure, temperature, required accuracy and output signal. Flow-meter calibration services are also available.
