YSI EXO pH & ORP Sensor Replacement Module

Smart, cost-saving technology for water quality measurements.

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 12-18 months for pH/ORP, depending on use).

Note:

• Not for use in EXO2 systems with a central wiper installed.  
• EXO sensors and modules are not backwards compatible with 6-Series sondes.
