I used to have a metrology company, and have owned and sold many DWT's. This is a rather lovely machine which I kept a home (amongst other machines) to show friends etc the wonders of industrial technology. This machine is superbly accurate and has offset figures for 250ft ASL. Complete with adaptors and instructions. Will calibrate any gauge (air gauges make sure you mount on extension or make sure of an air gap). Weights for up to 150 PSI. As twin ports can compare calibrate any gauge. If you buy and are new to DWT I can send you a 'how to' PDF Any questions please ask Thanks for looking Postage it to mainland only, contact for other prices If you want to collect, it's from WR15 8JJ
