Functions

• 1, Includes pH measurement for the actual sample pH.
• 2, When pH falls below 12.0 the booster module air pump starts automatically to maintain sample alkalization.
• 3, The pH control band is configurable so the air-pump start pH can match site requirements.
• 4, A float switch keeps the air pump off when no sample is present, reducing diisopropylamine use; measurement starts automatically when sample returns.
• 5, Constant-flow design for more stable readings.
