Introduction: Typical application of GT90 automatic potentiometer: determination of acid value in food; determination of chloride ion in cement; determination of peroxide value in food; determination of reducing sugar in food; determination of fatty acid value in corn flour; determination of free fatty acid; Acid content determination; soil organic matter determination; COD determination in wastewater; surfactant determination; electrolyte determination; mercaptan sulfur determination; Features: 1. Containing 4 channels, 20-station automatic turntable, channel titration module, connecting 20-position sampler and 34-position autosampler 2. It can drive multiple dosing module units, and the burette and pipeline should be resistant to acid, alkali and corrosion. 3. High precision closed loop control to ensure accurate titration 4. High precision burette accurate to 0.003mm 5. Automatically check the status of the instrument after power-on 6. The whole pipeline is fully sealed design, which is quick and convenient to replace 7. Real-time display of titration curve and measurement results, easy to operate 8. Support acid-base titration, oxidation-reduction titration, precipitation titration, complexometric titration, non-aqueous titration and other titration methods 9. In line with GMP specifications, titration results meet GLP requirements 10. Automatic sample loading, automatic cleaning of pipelines, automatic measurement of experimental results, automatic recording and drawing of titration time pH-titration volume real-time change curve. technical parameter: Measuring range: -2000.0MV～+2000.0MV -20.000PH～+20.000PH Resolution: 0.1MV 0.001PH Accuracy: 0.1MV 0.002PH Measurement mode: MEAS: measure pH/mV/T CAL: pH calibration (multi-point) SET set the end point mode MET isometric titration DET dynamic titration Titration mode: acid-base titration, redox titration, precipitation titration, complexometric titration, non-aqueous titration Temperature measurement range: -5～120℃ Temperature measurement accuracy: ±0.1℃ Communication method: 2 USB, 232 serial ports, Ethernet Dosing unit: Built-in dosing unit Simultaneous dosing module unit: (standard configuration) with 4 sets of built-in titration dosing channels Expandable number of dosing channels: 8 channels Burette specifications: 1ml 5ml 10ml 25ml 50ml (10ml standard) The resolution of the burette: 1/48,000 Burette refilling time: 10 seconds (100% filling speed) Control unit: PC with software (optional computer) Autosampler: (standard configuration) GT Robotic Sampling System is used in conjunction with the analysis of large quantities of samples Self-check function: automatically check the status of the instrument after power-on Calibration function: Yes Application editing function: Yes Storage space: more than 300G Default method: greater than 300G Compliance with FDA, GMP, GLP: audit trail, hierarchical management, electronic signature Tubing: PTFE titration tubing (corrosion resistant) Stirring method: overhead spiral stirrer or magnetic stirring PTFE valve: (imported) corrosion-resistant rotary valve
