To ensure accurate monitoring, keep the electrodes free of contaminants by periodic cleaning. The frequency of cleaning depends on the particular application. Automatic cleaning using the optional jetwash system and controlling the cleaning solution using a suitable controller or analyzer, will reduce the amount of manual cleaning.Methods of removing various types of deposit are detailed below. Replace the sensor if the performance of the sensor does not improve after cleaning.5.1.1 General Sludge and Loosely Adhering Matter Rinse off the excess matter and wipe the sensor with a soft cloth or tissue before calibrating.
5.1.2 Heavy, Non-Greasy Deposits For example: lime, salts, etc.Immerse the sensor in 1 to 2 M hydrochloric acid until the deposit has dissolved. Rinse with demineralized water before calibrating.
5.1.3 Greasy or Organic Deposits
Wipe the glass membrane with a detergent or acetone-based solvent. Rinse with demineralized water before calibrating.
