Recommendation for waste water: Precision measurements in the lab
pH Meter:
Electrode:
- Unitrode – combined LL pH glass electrode with Pt 1000 temperature sensor, fixed ground-joint diaphragm, fixed cable
Accessories:
- Cable, 1m (other lengths available)
- Buffer solutions
- pH 4, pH 7 and pH 9 (30x30 mL sachets)
- Electrolyte solution c (KCl) = 3 mol/L, 250mL (for Ag/AgCI reference system)
- Storage solution for pH glass electrodes
Additional options
- Stirrer
- Printer
- Software
- Metrodata Vesuv 3.0 for Windows
Your advantages:
- The 780 pH meter has an automatic electrode check, which gives you information about the state and performance of your electrode at any time
- The stirrer can be controlled directly over the 780 Metrohm Serial Bus (MSB) interface
- The Unitrode can be purchased in different lengths from 125 mm to 450 mm
- The fixed ground joint diaphragm of the Unitrode stops back diffusion of the sample into the reference chamber of the electrode. The electrolyte solution can not be contaminated with sample
Practical hints
- If the diaphragm of the Unitrode is blocked there is no need to use chemicals in order to clean it. With a soft brush you can remove the impurities which have accumulated on the diaphragm surface
- Do not use an electrode with a ceramic pin diaphragm!
