Specification notes
Temperature: the meter has no temperature input — enter the sample temperature manually (MTC) for correct pH compensation.
Electrode: the standard E-201F is refillable: keep it filled with 3 M KCl (PRO6126) — see page 4.
Upgrade: for automatic temperature compensation and data memory choose VIKING-PH210; for USB and GLP choose VIKING-PH310F / PH310T.

The standard pH composite electrode E-201F (PRO6135) connects to the BNC (Q9) input. BNC electrodes connect directly; S7-head electrodes connect by cable. The meter has no temperature input, so 3-in-1 electrodes with a temperature sensor are not used with VIKING-PH110. Standard delivery is confirmed in the quotation.
