  1. No more back strain injuries... Review by Micheal
    Ease of Use

    We purchased the Nitropak to reduce the risk of back strain injuries caused by wheeling around a D size or G size N2 cylinder. With the Nitropak, the charge / test unit is in a manageable carry case with its own N2 supply which can be charged without moving any heavy cylinders. The carry case allows us to take the unit to each work place easily. (Posted on 13/11/2015)

  2. Brilliant pressure source Review by Brett Lapham
    Ease of Use

    After being the first person to purchase one of these pressure calibrators the floodgates have opened. Many others have now found how good these units can be when multiple high pressure calibrations need to be performed around a site. You will soon be happy you don't need to drag heavy nitrogen bottles around any more. (Posted on 4/12/2014)
