They are designed for educational lab applications where sensors are calibrated, and tests are conducted and completed in a short time period. <em>ISE sensor membranes have a limited shelf-life and change over time, so regular calibration (perhaps every use) must be performed. <\/em>Vernier ISEs are for educational use only, not for industry, medical, hobby, or commercial use.<\/em><\/p>\n<h3 class=\"wp-block-heading\">Go Direct ISE with Arduino<\/h3>\n<p class=\"wp-block-paragraph\">Go Direct ISE readings are reported in mV by default.
