This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of a Calcium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.

Unlike a traditional thermometer, Go Direct Temperature allows students to collect real-time temperature measurements of a single instance or over a period of time. Its range and wireless capability make it the go-to sensor.
