The PRO 511 and PRO 515 are top-of-the-range professional pH meters offering a wide range of features, high-grade robustness and user-friendly operation for safe and reliable use in water analysis applications. The PRO 515 has data logging capabilities. Its water, drop and impact protection make it a perfect choice for field use, and its integrated pop-up stand makes it ideal for laboratory use. The specialized BNC + temperature input allows the use of cost-effective electrochemical sensors, such as pH electrodes, which provide IP water protection. The analogue input is practical and economical. The banana-plug temperature input allows operation with pH & T combi-electrodes or pH electrodes plus separate temperature sensors, such as the GF1T-T3-B-BS. Calibration is comfortably automated – the user interface will guide you safely through the process. The multilingual graphical display with a live chart feature sets this instrument apart from traditional pH meters on the market.
