Product model: TOH900
Measurement Principle
The instrument uses the continuous flow analysis technology to complete the automatic sample sampling and automatic analysis, through the automatic titration technology to measure the optical signal changes in the mixing process of the sample and titrant to complete the automatic alkalinity analysis, and finally the total alkalinity value of the actual water sample is calculated by comparing with the standard known alkalinity material.
System overview
The TOH900 online water quality alkalinity analyzer is typically used to measure the total alkalinity of industrial boiler water, circulating water and drinking water.
Measurement method
optical titration.Can Achieve a Variety of Choices:
Timing measurement can be realized every day in any user want to monitor the time to start the instrument for measurement;
Isochronous measurement can automatically start the instrument for measurement every few hours at a fixed time interval every day;
Continuous measurement can realize automatic sample measurement one by one, which can be used for product acceptance and related technical certification;
Manual measurement can realize the user to start the measurement at any time, and can be used for field experiment comparison and equipment installation and debugging;
