We are looking for a temperature controller or a temperature sensor/probe which can work for a pH range of 2-12. It would be nice if it can be integrated with a readout (using Arduino or any other hardware), so that the data can be plotted. We want to monitor and control the temperature of solution while carrying out our experiments. We have looked at temperature probes but not sure if they are compatible with highly basic or acidic solutions, primarily pH buffer solutions.
Fiber optic temperature sensors based on fluorescence decay time or fiber-bragg grating are extremely inert.
Is there any good liquid immersable thermocouple suitable for wide pH range?
Temperature sensors can be placed in a glass case. Type Pt100. Pt1000
temperature range -50-200 ° C
in terms of just the temperatures sensor for that pH and temp range try a bead thermistor https://www.mouser.co.uk/amphenol-advanced-sensors-thermistors/
which comes encased in glass. Its resistance is directly related to temperature - it's very easy to make a circuit to output temp on a scale of your choice.
