noticias de la compañía sobre How Does Temperature Compensation Improve Accuracy in Conductivity, TDS, and Salinity Measurements?

Temperature is one of the most influential factors in the measurement of liquid conductivity. As the temperature of a solution increases, the mobility of its ions also increases, leading to a higher conductivity reading even if the chemical concentration remains unchanged. To counteract this, a modern single-channel conductivity controller utilizes an integrated temperature sensor—supporting ranges from 0 to 60°C up to 135°C—to perform automatic temperature compensation (ATC). This ensures that the displayed conductivity, TDS, and salinity values are normalized to a reference temperature (usually 25°C), providing an accurate reflection of the water's actual mineral content.

For specialized applications like pharmaceutical distillation or food processing, sensors must be able to handle high thermal loads. A sensor rated for 0~120°C or 0~135°C is not only capable of measuring hot fluids but is also built to survive thermal shocks during cleaning cycles. Whether the sensor is made of food-grade stainless steel or medical-grade ABS, the ability of the controller to process temperature data alongside the analog signal is what allows for the calculation of complex parameters like resistivity. Without accurate temperature data, the data provided by a sensor measuring 0.5 to 200μS/cm would be unreliable, leading to potential errors in process control and product quality.
