WTW SenTix® 41 and SenTix® 81 are high-quality pH electrodes designed for both field and laboratory applications. These electrodes are used primarily in microbiological analysis and food safety applications. Both SenTix® 41 (epoxy body, gel electrolyte) and SenTix® 81 (glass body, liquid electrolyte) models provide high accuracy and sensitivity. Both models offer superior performance with integrated temperature sensors and wide pH measurement ranges.

SenTix® 41 is the ideal choice for field conditions with low maintenance requirements, while SenTix® 81 is preferred in laboratory environments for more precise measurements. Both electrodes can be used in a wide range of applications to provide reliable and accurate pH measurements.
