WTW pH Electrode for special applications

WTW SenTix® pH Electrodes for special applications
The consistencies of samples in which pH is measured are very different. Liquid or solid, low-ion medium or highly concentrated, aqueous or non-aqueous phases, with or without suspended solids. In some cases even smallest volumes have to be identified and sometime glass is not acceptable. All of this can be tackled using the specialists of WTW: For measurements in or on solids, penetration or surface electrodes are recommendable. The split ring electrode with liquid filling is suitable for determining the pH value in low-ion or concentrated solutions and also for emulsions. Samples with suspended solids can be determined the easiest using a polymer electrode. Microelectrodes can help when there are only low volumes available.

SenTix® quality electrodes by WTW - convenient measurement and precision.

• Low-resistance glass membranes guarantee stable measuring signals even at low temperatures.
• Silver ion-free reference electrolyte, together with the proven platinum wire diaphragm, prevent measurement problems by precipitating silver compounds.
• Functional slide for accessing the refill opening for electrodes with liquid electrolyte.
• Connectors: Waterproof DIN connector, BNC connector, fixed cable (1 or 3 m, 3 ft. or 9 ft.) or plug head (S7 or SMEK).
