I am looking for a pH meter with a transmitter specifically designed to measure the pH of water glass liquids at a maximum temperature of 98 degrees Celsius and at atmospheric pressure. It's crucial that this instrument maintains accuracy under these conditions. Additionally, I'd like to know if the pH probe needs to be continually immersed in the liquid for precise readings, or if there are alternatives that allow for occasional measurements without full immersion. Could you please provide details about the specific models you have that meet these requirements? I'm also interested in any recommendations you might have regarding the best practices for using the probe and maintaining the accuracy of the readings in such high-temperature environments. Thank you!
