Precise Measurement and Reliability for Laboratories
The Knick 766 laboratory pH meter is a measuring instrument designed to meet the stringent requirements of laboratories for pH, redox potential, and temperature analysis. It combines ease of use and precision, featuring an intuitive interface that allows quick access to all necessary functions for reliable routine measurements. With its stainless steel housing and IP54 protection, it withstands harsh conditions, ensuring long-term durability.
One of the key advantages of the 766 lies in its Gaincheck system, which performs an automatic diagnostic check upon startup. This built-in control ensures the proper functioning of the instrument by verifying its electronic circuits, display, and keypad. This feature is particularly useful in compliance with ISO 9000 quality standards and Good Laboratory Practices (GLP), where instrument traceability and reliability are essential.
Electrode monitoring is managed by the Sensoface system, which continuously analyzes their status. It evaluates zero point, slope, response time, and glass impedance. This real-time feedback allows users to immediately assess electrode quality and anticipate replacements if necessary, ensuring measurement reproducibility.
Calibration is simplified with the Calimatic function, which automatically recognizes buffer solutions. Users simply immerse the electrode in two solutions, in any order, and press a button for the device to perform the calibration. This procedure minimizes errors and ensures high measurement accuracy, a crucial factor for laboratories that prioritize analytical precision.
The 766 pH meter features a clear, readable LED display, allowing simultaneous reading of pH/mV and temperature. The temperature compensation system, available in manual or automatic mode, guarantees accurate measurements despite temperature fluctuations. The device supports Pt 100 and Pt 1000 temperature electrodes, offering flexibility for different analytical needs.
To ensure maximum protection against electromagnetic interference, the 766 model is designed according to EMC standards under the NAMUR directive. This design ensures stable and reliable measurements, even in disruptive environments. The Trueline analog output provides a calibrated and electrically isolated pH signal, allowing precise recording of pH variations without distortion.
The instrument is highly ergonomic and user-friendly. It features a sealed membrane keypad and a simple five-key navigation system, making it intuitive to operate. Additionally, it is compatible with a wide range of standard electrodes available on the market, thanks to its universal DIN or banana plug connection.
Designed for long-term use, the 766 pH meter includes an integrated memory for secure storage of calibration data and measurement parameters, ensuring their preservation over time. With its robust construction and multiple monitoring functions, it is an ideal choice for laboratories requiring a precise, reliable, and easy-to-maintain instrument.
