IDS pH Electrodes

pH measurement covers a wide variety of applications, from routine analysis of aqueous samples to specialized measurement in challenging media such as strong acids, strong alkalis, suspensions, emulsions and non-aqueous matrices. Samples can range from fully liquid to solid consistency. Measurements can be performed in sheltered laboratory environments or outdoors under harsh field conditions. For all these diverse measurement scenarios, the IDS electrode portfolio provides suitable solutions.

IDS pH Electrodes for Water, Wastewater and Other Aqueous Samples

· SenTix® 940(-P): Low-maintenance pH electrode with robust plastic shaft and gel electrolyte

· SenTix® 945(-P): Low-maintenance, fast-response pH electrode with gel reference system and three ceramic junctions for laboratory use

· SenTix® 950(-P): Robust, liquid-filled electrode with plastic shaft and ceramic junctions for portable field measurement

· SenTix® 980(-P): Precision pH electrode with platinum wire junction and glass shaft for laboratory use

· SensoLyt® 900-P: Pressure-resistant pH electrode with polymer electrolyte for depth measurement

pH Electrodes for Special Samples (Suspensions, Emulsions, High and Low Ion Concentrations)

· SenTix® HW-T 900(-P): Precision pH electrode with liquid electrolyte; adjustable split ring junction

pH Measurement in Semi-solid or Viscous Samples

· SenTix® Sp-T 900(-P): pH electrode with spear-shaped membrane for penetration measurements

pH Measurement in Small Vessels

· SenTix® Micro 900(-P): Micro pH electrode with 5 mm shaft diameter and built-in temperature probe

Core advantages of IDS sensors

1. Secure measurement values by means of signal processing inside the sensor

2. Easy electrode exchange thanks to calibration data stored in the sensor

3. Sensor quality monitoring through QSC function
