This option allows the analyzer to perform an automatic calibration at programmed
intervals and with a known calibration solution. Three different kits are available, each
including a 10 liter canister equipped with level detector and strainer:
1. 1 point calibration with a volumetric pump.
2. 2 point calibration with a micro piston pump.
3. 2 point calibration with a pulse pump.
