Available Models
Useful for industrial and laboratory applications, e.g. in cheese production, slaughterhouses (HACCP process monitoring), breweries, verification measurements, as well as measurements carried out under field conditions. The smooth foil keypad for heavy-duty applications is chemically resistant and easy to clean. Easy-to-read liquid crystal display.Ergonomic design. Explosion-proof version available (EEX ia IIC T6 and FM Class I Div I).
The Calimatic system automatically performs all functions needed to calibrate the sensor/electrode, including single-point calibration or two-point calibration if so indicated by the user. An innovative feature of Sensoface provides information on the status of the sensor/electrode displayed in the form of corresponding 'buzzers'.
The data logger is capable of storing up to 100 measurement results including pH, temperature, date and time; ideal for use in ISO and GLP compliant management systems. Communication via RS232 serial interface, bi-directional; can be used to connect a printer or computer.
The convenient and ergonomic design with IP66 protection makes the pH meter 1140 useful in all types of applications. The integrated real-time clock allows the measured values to be stored properly arranged and assigned.
Oprogroamme is supplied with the meter and provides a convenient way of establishing documentation and further processing data on the computer. This guarantees access to quality management documentation that meets ISO 9000 and GLP requirements at all times.
