Do I Need Calibration?
Calibration is an essential part of any business where quality and accuracy are of the greatest
importance. Your instrumentation must perform consistently throughout its working life, so it must
be regularly serviced and inspected to ensure it is working within the correct tolerances.
GNW are certificated to ISO 9001 and we provide a full calibration service in accordance with these
standards. Specific UKAS accreditation is available on request.
In House Calibration
Operating from our premises in the North West, our experienced team of specialists can carry out a thorough service and calibration of your equipment – quickly, efficiently and precisely. We know that the equipment you have is the equipment you need, so we don’t hang about when it comes to getting it back to you. A lot of the equipment we calibrate can be turned around in just a few days. If you find your calibration cheaper elsewhere, please contact us – and we will beat the price!
On Site Calibration
We don’t just service in house! If for any reason you can’t send your item to us, we can arrange for our qualified uniformed engineers to come to you instead, anywhere in the UK. Give us a ring to chat about our availability and pricing.
Scale & Balance Calibration
Our skilled technicians are able to calibrate and certify scales from any manufacturer. We are able to do this on our premises or alternatively our engineers are able to visit your site. We use either M1 or F1 calibration weights to ensure your scales are performing correctly.
We have over 40 years’ experience in calibrating pressure and vacuum gauges. Our technical team is able to calibrate and certify gauges from any manufacturer using our accurate, traceable test equipment.
Dimension Measuring & Tool Room
Our technicians are able to calibrate all types of tool room and dimensional measuring equipment. Our capabilities include everything from small hand tools such as verniers, digital calipers and micrometers, to precision tooling such as threaded plug and ring gauges.
Electrical Test Equipment
Electrical test equipment not only forms an important part of ensuring product quality, but it is often used for critical safety tests of installations and equipment. Making sure that your equipment is performing correctly should be a top priority.
Crimping tools calibration ensures that your tools are performing as designed. Electrical connectors are often safety critical areas that need tight QA control. We can calibrate and certify crimp tools from all manufacturers.
GNW technicians can calibrate all types of flow meters and rotameters (variable area flow meters). We are able to calibrate air, water and other media flow meters at our premises.
Gas Detectors & Monitors
GNW is able to calibrate all types of single and multi-gas detectors and monitors. Regular calibration and servicing of these meters is an important task that should not be overlooked.
Light meters are used in many production and occupational safety processes, therefore it is important that they are regularly calibrated to make sure they are performing to the manufacturers specification.
Moisture & Humidity Meters (Hygrometers)
GNW can calibrate hygrometers from all manufacturers. Moisture levels in the atmosphere or in products can affect decisions in production and storage.
Ph & Conductivity Meters
pH meters and conductivity meters can be calibrated at our premises or at your site. Regular calibration makes sure that your instrumentation is performing as expected and to within the manufacturers specification.
Test weights are used to check the accuracy of your own weighing equipment such as scales and balances. If you are performing your own calibration checks then it is vitally important that your own calibration weights are within the OIML tolerances.
We Don't Just Calibrate!
GNW also repair, manufacture and design instrumentation across a diverse variety of industries, so if we discover that your item isn’t performing as it should, we can fix it for you. We would inform you of any issues along with a quotation and wouldn’t proceed unless you told us it was ok to do so.
