The model 31 has been replaced by draeger accuro 2000 hand pump. For the enclosed document you can see some detail information. For the hand pump doesn’t use any power, it’s pure mechanical principle, if there isn’t any leakage, it doesn’t need to do the volume calibration, just do the leakage test is enough. Last year, we lunched new automatic tube pump, it has many outstanding features like barcode operation, auto gas flow……, it’s especially for the large stroke tubes, and its volume can be calibrated by calibration tube.
