What is the expected life of Hach electrodes?
Expected lifespan of a pH electrode
This is impossible to determine as any electrode will have variable life expectancy depending on factors such as sample type, frequency of use, and maintenance. Most customers can expect approximately one year on gel filled pH and ORP electrodes, about 1-2 years on refillable pH and ORP electrodes, and about 2 years for combination ISEs (Ion Selective Electrodes). Although there is not guarantee that all customers will able to get equivalent use out of their electrodes before they would need to be replaced.
