This sensor features a “long life” reference electrode eliminating the need to frequently replace the electrode cartridge. However, cartridge replacement is simple and may be performed by the end-user in the field.
This sensor has been designed for both handheld and in situ applications and offers quick time response, minimal flow dependence and low power consumption.
