NDM CALIBRATION METHOD

We apply the most advanced method of calibration available today – the international three-block calibration that Troxler Electronic Laboratories developed as an advance over the older five-block procedure. 
We stock all the commonly used parts. 
We calibrate all brands and models of nuclear density gauges currently in use in NZ. We use the three-block method according to NZS4407.
