This probe can be used with all pH meters that have an input for the BNC connection with a 3m long cable. The sensitive part of the probe (in the shape of a ball) is partially protected by a probe's plastic body that makes the possibility of mechanical damage significantly reduced.
The EPH101 is used to measure the pH value of various liquids (due to the present plastic protection), and it can also be immersed in liquids that are inflow in a system). It is stored in a plastic bottle with gel and has a very long shelf life.
