The Zahm SS-60 Volume Meter was developed to determine average CO² levels of gas in tank stored beverages. Its improved design over the older Zahm-Hartung Volume Meter (Series 2000) greatly improves accuracy and time required to run a test. A precise piston release mechanism eliminates bleeding off of the sample and the potential for human error. Samples undergo repeatable, precise volumetric expansion test after test for more accurate measurements. The lightweight design reduces operator fatigue while the stainless steel construction increases strength and resists corrosion. The thermometer may also be replaced in the field without the need to return it to the factory for replacement. The parts list and line drawing should be used when ordering replacement parts or operating the instrument.
