YSI EXO Chloride Sensor Replacement Module.
User-replaceable tip for #599711 - EXO Chloride Smart Sensor
Exhaustible reagents are stored in this replaceable module and can be swapped-out as needed. Electronics & data are stored separately in the smart sensor base. Grants long-term costs savings by eliminating the need to re-buy the entire sensor after the reagents are depleted (approximately 3 months for ISE's, depending on use).
