At ZP we do get enquires about our electrochemical pH sensors, so we have made this page to answer some more FAQs.
QUESTION ONE - How many hours of continual use in simple aqueous solutions at pH 3-5 could the printed sensors withstand before significant degradation?
QUESTION TWO - How long would the sensor lifetime be in complex bio-fluids with additional ions (eg Na+, K+)?
QUESTION THREE - Can the sensors be reused (eg with a suitable washing step) or would you recommend one-time use?
QUESTION FOUR - Approximately how many bending cycles can the pH sensor withstand?
