Robust and Reliable: Designed for industrial applications, it guarantees maximum electronic, mechanical, and hydraulic reliability. The complete separation of the electronic and hydraulic systems, combined with the extreme simplicity and robustness of the hydraulic circuit, ensure safe and reliable long-term operation.
Automatic Calibration: At intervals set by the operator, the analyzer performs automatic calibration, triggering an alarm if the measured calibrant value is abnormal.
Automatic calibrationAt times specified by the operator, the analyser performs automatic calibration, producing an alarm signal if the measured calibrant value is anomalous.
Test frequency: Programmable by the operator; between tests, the analyzer enters standby mode without consuming reagents.
Reanalysis of out-of-range results: The analyzer detects out-of-range results and reanalyzes them “in dilution.”
