Turbidity Sensor

Installation

Immerse the sensor into the sample and ensure that the tip is fully installed so as to avoid the sensor head being affected
by air bubbles.
Calibration
The turbidity sensor has been calibrated before leaving the factory. Self-calibration is rarely required. If calibration is
necessary, please see the standard liquid that is required for suspension concentration calibration. The specific configuration
is as follows.
Preparation Method (Turbidity Standard Liquid 200mL 4000NTU) :

1. Accurately weigh 5.000g of Hydrazine Sulfate (GR) and dissolve it in zero turbidity water. The solution is then transferred
to a 500ml volumetric flask, diluted to scale, shaken and filtered (filtered with 0.2μm aperture, same below).
2. Accurately weigh 50.000g of Methenamine (AR), dissolve it in zero turbidity water and transfer it into a 500ml
volumetric flask, dilute to scale, shake well.
3. Preparation of 4000NTU Formazine Standard Solution: Transfer 100ml of each of the above two solutions into a 200ml
volumetric flask which is placed in a 25 ± 1°C incubator or constant temperature water bath. Let stand for 24 hours to
make 4000NTU standard solution.
