Laboratory pH meter Knick 765

With many safety features making pH measurement easier and more reliable.

Fullcheck® automatically checks instrument function from input socket to recorder output. Functional efficiency of the instrument can be documented as part of quality management in accordance with DIN EN ISO 9000 using a test print. Drycheck® monitors electrode impedance and alerts to electrode dry-up, glass breakage and defective connections even in stand-by mode. Sensoface® monitors the electrode performance and gives information on electrode condition, evaluating zero point, transductance, response time, electrode impedance and calibration intervals.

Trueline® delivers a calibrated analog recorder signal (electrically isolated). Calimatic® automatically recognises the correct buffer. EMC design protects instrument from electromagnetic interference. The 765 laboratory pH meter complies fully with NAMUR (German committee for measurement and control standards in the chemical industry) EMC recommendations.

Temperature compensation is either automatic with a Pt 100 or Pt 1000 sensor or manual. Data can be processed immediately by a computer via standard RS 232 interface. Direct output to a printer is also possible. Large, bright LED display enables simultaneous readout of 2 measured values, such as pH value and temperature.
Case made of glass reinforced PA, with non-rusting, stainless steel, IP 54 protection level cover, ready for connection of ZU 6954 electrode stand.
Alpahnumerical display, 2 x 4 digits, 14 segment, 13 mm characters, 3 Sensoface status indicators.

Interface:
RS 232 without control lines, galvanically isolated, printer or computer interface.

Printer control:
Via serial interface for ZU 0244 or other standard printers, printing at the touch of a button or via print interval timer 0.1 to 999.9 min.

Electrode monitoring:

  • Sensoface®:analysis of zero point, transductance, response time and electrode glass impedance, good/average/poor optical display for monitoring electrode condition can be disabled.
  • Drycheck®: Monitors electrode impedance and alerts to electrode dry-up, glass breakage and defective connections even in stand-by mode. Calibration timer monitors calibration interval.

Instrument self-test system:
  • Fullcheck®: tests all measurement electronics, including analogue output, segment and keyboard test in diagnostic mode, automatic short test after power-on, QM documentation print-outs according to DIN EN ISO 9000 retrievable in diagnostic mode or via interface (printer).

Laboratory pH meter 765, includes mains cable, electrode not included, 3 year guarantee.
Laboratory pH meter 765 SET, with electrode statistics (Opt. 347), pH/Pt 1000 SE 100 combination electrode, ZU 6954 attachment stand and ZU 6928 buffer set (no other optional ancillary equipment available).
