Accuracy is our trademark at TN UK. We pride ourselves on our ability to measure and calibrate the products we manufacture. Housing some of the most sophisticated equipment in the world, our annually assessed UKAS lab means we guarantee the precision of the products we supply.
On top of that, we maintain regular and open communication directly with you and any relevant departments to ensure that you get exactly what you need when you need it.
We also offer a recalibrate service for your existing gauges, CMM Reference balls and Master Ball Sets. So you can rest assured that, whether we are supplying a new product or recalibrating an existing one, by meeting our strict standards, your company meets its strict standards (particularly important for other calibration assessed companies).
