The sensitive glass bulb at the front of the combination electrode should not come in contact with hard surfaces. Scratches or cracks on the electrode will cause inaccurate readings. Before and after each measurement, wash the electrode with pure water and then throw off the excess water on the electrode. Do not clean the glass bulb with a tissue for it will affect the stability of the electrode potential and increase the response time. -

(a) For inorganic pollutants, submerge the electrode in 0.1mol/L dilute hydrochloric acid for 30 minutes, then wash it in pure water, then submerge it in the soaking solution for 6 hours. (b) For organic or lipid pollutants, clean the platinum surface with detergent, then wash it in pure water, then submerge it in the soaking solution for 6 hours. - Page 16 6.2.2. Calibration intervals (a) The meter is calibrated before leaving the factory and can be used right out of the box. (b) Perform calibration once per month. (c) For high accuracy measurements or large temperature deviations from the reference temperature (25°C), perform calibration per week.
