The Calimatic® system automatically carries out all necessary unit functions for calibration of the sensor,
including single-point or dual-point calibration as selected. The novel Sensoface® feature provides information
on the condition of the sensor by displaying appropriate “smilies”. Both instruments, 1120 and
1140, are also available as Ex-proof versions.
The innovative design allows optimum use of the meter in a whole variety of applications. The datalogger
of the 1140 can store up to 100 measured values covering pH, temperature, date and time. These features
make this instrument unique in its class. Despite the extensive range of sophisticated features, operation is
extremely simple.
