The AK131 Max is the ideal choice for laboratories that require a robust, high-performance instrument with features that ensure accuracy, traceability, and reliable results. The instrument has GLP (Good Laboratory Practices) functions, which allow you to set the validity of the last adjustment made, check which standards were used, monitor the results obtained, and consult the slope of the pH electrode.
Key Features: GLP functions (Good Laboratory Practice): stores calibration date, standards used, electrode slope, and measurement history. Temperature compensation: automatic (ATC) and manual (MTC). Calibration standards: USA and NIST. Illuminated LCD display for clear pH and temperature readings in any lighting condition. Memory for up to 1000 records (manual or automatic), ensuring full traceability. PC communication via USB for easy data transfer. Printer communication via RS232 for direct report printing. Optimized for pH measurements, but also capable of ORP measurements with an optional electrode.
