The Zahm Computerized Piercing Device is a newly developed instrument for testing volumes of C0₂ gas in bottles and cans. Gas volumes are measured directly by the computer; thereby eliminating the need for C0₂ gas conversion charts and yielding very accurate, reliable results even in the hands of an inexperienced operator. Both temperature and pressure are LCD displayed and can be re-calibrated by the operator. Two C0₂ conversion tables can be installed in the computer (for example, sugar and diet beverages/beer and water). Data memory and read out are available for 5 samples. Altitude correction factors can also be entered. Available in one and two litre sizes. Computer and thermometer may be ordered separately for attachment to existing Zahm Piercing Devices. Please specify when inquiring about this instrument whether you wish a beer or soft drink model.  Soft drink models also need to indicate whether the unit is for a Coca Cola plant since these require a different formula in the computer.
