About pH meters
Thread Content
When conducting pilot-scale organic synthesis experiments, it is necessary to control the pH value of the reaction mixture and keep the system sealed; however, conventional pH electrodes are too large and prone to being damaged by the stirrer blades. Is there a pH meter that is more compact and more secure, and can be fixed to a rubber stopper?
I haven’t seen any thin ones, but they should exist. You can look for suppliers or first ask the manufacturers yourself
You can put yourself in their shoes; if that doesn’t work, just use a larger reactor one that can hold the pH meter – that’s exactly what I did!
Ask Mettler; they might have what you need. If not, you’ll have to use a larger reaction vessel.
There are several types of pH meters, so there should be one that suits you
There is a small tube membrane pH sensor for monitoring the pH value in solutions; its advantages include resistance to contamination and corrosion, a long service life, and the ability to enable fully automatic online acidity monitoring.
You can consult relevant manufacturers, such as Mettler Toledo, E+H, Rosemount, and the like
Alternatively, you can try ROSEMOUNT pH meters, which usually come with a very complete protective lining, with only a small portion exposed
Use a larger reactor that can accommodate a pH meter.
Ask the manufacturer; it should be available. Our factory uses one that looks like a probe, but I’m not in charge of the instruments and don’t know much about them.
Search for agents on online magazines, then call their customer service hotline directly
Ugh, just try a different angle; use a different magnetic stirrer and it’ll be fine……:lol
I wonder what kind of pH meter the original poster is using? Classification of PH pH meters Based on the needs of production and daily life, many different models of pH meters have been developed through scientific research. In terms of measurement accuracy, they can be classified as having an accuracy of 0.2 grade, 0.1 grade, 0.01 grade, or even higher precision. Based on their size, instruments are classified into pen-type (miniature), portable, desktop, and online types for continuous monitoring and measurement. Based on the usage requirements: Pen-type (miniature) and portable pH meters are generally taken to the site by inspectors for on-site testing. The accuracy level of a PH meter is determined based on the precision required for the user’s measurements, while the various shapes of PH meters are chosen to facilitate ease of use for the user.
