How to select an industrial online pH meter? Several types of parameters are required; in addition to the medium, temperature, and pressure, what other parameters are needed?
Medium, temperature, pressure, electrode installation method, length of electrode signal wires, whether the water quality is corrosive, concentration of corrosive substances, accuracy, power supply, output, whether digital signals are required, protection and explosion-proof ratings, etc
Conductivity: electrodes with low and high conductivity are different
Medium: Isopropylamine, organic substances, acidic medium, water； The maximum temperature is 75℃ ； Pressure: Atmospheric pressure ； Electrode installation: top-insert type ； Length of electrode signal cable: 1.5–2 meters ； Accuracy 0.01 ； Power supply: 24V; protection and explosion-proof rating: ExdIIBT4. Help check if there is a suitable option; the main concerns are safety and explosion prevention, as well as whether a short circuit that occurs after damage to the electrodes could lead to an explosion
What we produce are intrinsically safe explosion-proof pH meters, with an explosion protection rating of E*aIICT6; there is no risk of explosion caused by electrode short circuits.
