Blood/gas analyzer. The unit measures for pH, PO2, and PCO2 using a standard sample of 90 microliters or greater. A measurement range of 6.4 to 8.0 for pH, 8 to 200mmHg for PCO2 and 0 to 800 mmHg for PO2 is accommodated by the unit. Used in laboratories to measure blood gas parameters of patient samples. System to provide for the measurement of: pH, pCO2, pO2, BP, tHb, NA+, K+, and CL-, or CA++. Calculated values to include: tCO2, O2 Saturation, CT, HCO3 (actual and standardized), BE (vv and vt) and Hct.
