On-site measurements and testing is essential for rapid monitoring of key process parameters such as pH, DO and MLSS. Present day hand held or portable instruments are now widely available to meet this need. The hand-held instruments along with on-line instrumentations provide real time measurements as quick gauge and indication of process conditions. Since these measurements and tests are meant to provide quick check and response, they need to be carried out correctly to ensure that the appropriate counter measures are being taken. This module covers the basic operational procedures such as calibration, care and maintenance as well as step by step operational guide on typical hand held instruments.
