Laboratory pH Meters
The 766 laboratory pH meter is designed for standard applications in everyday lab operation.
Gaincheck® performs a complete instrument check. At a keystroke it not only checks electrical characteristics, but also display and keypad. After power-on, a quick check automatically tests instrument operability.
Drycheck® monitors electrode impedance and alerts to electrode dry-up even in standby mode.
Sensoface® checks the electrode system and informs on electrode condition by evaluating the electrode’s zero point, slope, response time and glass impedance.
Trueline® delivers a calibrated analog recorder signal.
Calimatic® automatically recognizes the correct buffer. This allows calibration at a stroke of a key, providing ease of use and safety.
EMC design protects the instrument from electromagnetic interferences.
