Electrodes WTW DX 223 NA, etc.

Ion-selective 500 series indicator electrodes are designed for electrochemical measurements of the concentration of selected ions – combined electrodes are available, as well as half-elements.
Models: DX 223 NA, NH500/2, Ag/S 500 BNC, Ag/S 500 DIN, Br500 BNC, Br500 DIN, Ca500 BNC, Ca500 DIN, Ca500/AT, Cl500 BNC, Cl500 DIN, CN500 BNC, CN500 DIN, Cu500 BNC, Cu500 DIN, F500 BNC, F500 DIN, K500 BNC, K500 DIN, K500/AT, NO500 BNC, NO500 DIN, NO500/AT.

The combined ion-selective electrodes of the 800 series are excellent for operation and offer an additional opportunity to measure small volumes of samples, since the ion-selective and reference electrodes are combined in a compact rod housing.
Models: Ag/S 800 BNC, Ag/S 800 DIN, Br800 BNC, Br800 DIN, Ca800 BNC, Ca800 DIN, Ca800/AT, Cl800 BNC, Cl800 DIN, CN800 BNC, CN800 DIN, Cu800 BNC, Cu800 DIN, F800 BNC, F800 DIN, K800 BNC, K800 DIN, K800/AT, NO800 BNC, NO800 DIN, NO800/AT.

The most commonly used electrochemical sensors are pH electrodes.

SenTix pH electrodes are standard gel electrodes and high-precision liquid gel electrolyte electrodes for pH measurements in laboratory and field conditions.
Models: SenTix 20, SenTix 21, SenTix 21-3, SenTix 22, SenTix 41, SenTix 41-3, SenTix 42, SenTix 60, SenTix 61, SenTix 62, SenTix 81, SenTix 82, SenTix 51, SenTix 52, SenTix 91.

Special samples require the use of special electrodes. pH values of samples with low ion content, in minimal volumes and much more: there are no problems for special SenTix electrodes.
Models: SenTix H, SenTix Sp, SenTix Sur, SenTix Mic, SenTix HW, SenTix Mic-D, SenTix Mic-B, SenTix V, SenTix Sp-DIN, SenTix HWD, SenTix RJD.

ORP electrodes perceive and transmit a voltage signal that occurs due to the course of reactions in aqueous solutions, where the partner reagents exchange charges with the metal surface of the platinum electrode. The ORP measurement scale is comparable to the pH measurement scale. Typical applications are monitoring the disinfection effect, determining the potential of ORP in biochemical reactions, measurements in waters of different quality, and much more.
Models: SenTix ORP-T 900, SenTix ORP, SenTix Ag, SenTix Au, SenTix PtR, SenTix ORP-T 900-P, SensoLyt ORP 900-P.
