K-4500

Analyzer without feeder. Power supply 220-230VAC. The measuring block (there was a leak) along with the aluminum housing and the printer with the electronic module were exchanged with another analyzer (SN: AB429) (the printer failed to print the data several times). He had problems with repeatability (blood problem?, insulated measuring electrode?, dirty orifice?). The final repeatability measurement was in line with expectations. The analyzer is operational.
