The Series 11000 Piercing Device is a modified Zahm New Style Air Tester (Series 5000) with the burette (5003-25), burette clamp (5006), support rod (5016), level bottle & stand (5047/5050) & connection tubing (5052) omitted. This instrument is used where a separately mounted burette is preferred for air testing or where a fast, simple closure piercing unit is required to measure pressure. Where samples are tested at room or known temperature, gas pressure can be quickly obtained to determine CO2 gas volumes. Refer to the line drawing and parts list for ordering replacement parts.
