VCM, pH of caustic soda plant, ORP, conductivity, turbidity
Thread Content
Dear experts: Hello everyone! I’d like to ask for advice: which company does well in terms of pH, conductivity, and turbidity measurement for VCM plants and caustic soda plants? Key point: There are several points in the VCM device that are at 150°C. The turbidity of caustic soda after the first saltwater treatment is 0-1 ppm. Thank you
First, ask a few major foreign brands
DKK is the most commonly used for caustic soda; you can contact me at 13324528344
On our end, it’s Mettler Toledo’s pH and conductivity.
Asking which one is good is basically a pointless question. As process media for chlor-alkali and PVC production, they are associated with corrosion, interference, and toxicity; therefore, it is crucial to determine what costs the company is willing to incur to address these issues. If you want to use the most affordable conventional products, or adopt a bidding system based on the lowest price (without considering factors such as instrument specifications, configuration, material, or solutions), it’s best to avoid relying on established imported brands.
For caustic soda, DKK and Mettler are the main suppliers; nowadays, E+H is also used
