The line of laboratory pH sensors offer accurate and reliable measurements across full pH ranges (0-14), compatible with all pH meters. The Basic sensor has a polycarbonate body and built-in protection for the pH glass measuring surface to provide readings in temperatures of up to 60°C. The Advanced family is for more difficult sample types in environmental, wastewater, and food production applications. The standard and advanced models offer extended sensor life and measurement accuracy in temperatures of up to 80°C. The Research-Grade sensor is the most sensitive lab electrode and is specially designed to respond to rapid temperature changes up to 100°C with accuracy down to 0.04 pH.
