Selection of a pH meter
Thread Content
I’m new to using pH meters for alkaline solutions; I don’t know how to place orders or choose the right model. Could you tell me which brands your companies use? I’m looking for options with a good cost-performance ratio. The ones we used before were imported, but they weren’t very effective. Are there any domestic alternatives? The measuring medium is alkaline, and the temperature is quite high, at 85 degrees
Could you describe the process conditions and medium conditions at the site in more detail? Let’s talk about the requirements regarding power supply and installation methods. The selection of all instruments requires the user to provide information necessary for making such a choice. With such a rough description, only a more approximate configuration can be chosen; it’s impossible to guarantee whether it will work or be suitable.
Conductivity and ambient temperature need to be considered; I don’t know anything else.
Those who have used DELTA-V for online measurement find it pretty good, but the electrodes tend to break easily.
Foreign brands: Rosemount, E+H, Toledo. There are many domestic brands as well; the company I used to work at used Yantai Dongrun’s products, and they were fine.
