I remember using it before; it was used in combination with anodizing

If you have technical issues, you can go to the analysis section to discuss them. Because for specific testing, the selection needs to be made in consideration of the on-site conditions and sample conditions.
Well, it’s required to be imported as per the specifications. I checked a few domestic options online; they cost several thousand yuan, and I’m worried about their quality
Imports are also available; it depends on your requirements
Give me an introduction; mine is a liquid-phase pipeline type
Industrial conditions: 20-40% liquid acid, 60-80% water; the acid is mainly hydrochloric acid, with small amounts of trichloroethane and sulfurous acid present. The connection method is pipe insertion type; it features on-site display and 4-20mA output. Explosion protection is required, and the manager insists on an imported version
Online monitoring of hydrochloric acid concentration generally involves the use of a conductivity meter; however, given the operating conditions described by the poster, it is likely that such a meter will experience significant interference. Trichloroethane, which does not conduct electricity, has a considerable impact on the overall conductivity of the medium. At present, there are basically no good solutions available on the market for such operating conditions
