The HI764113-1 is the factory replacement optical cap for the HI764113 opdo probe, the dissolved oxygen probe supplied with the Hanna HI98198 Optical Dissolved Oxygen Meter. Fitting a fresh cap restores the sensing chemistry that the probe relies on, so the meter keeps reading to specification without membranes or electrolyte.

The kit arrives with the parts needed to carry out the swap: the Smart Cap itself with its o-ring, a 6 g sachet of silicone grease and a syringe for applying it, a lens wipe, and a certification and instruction sheet.

Smart Cap Technology

Automatic Cap Recognition
Each Smart Cap carries an RFID tag that the probe reads on contact. Manufacture date and first-use date travel with the cap, so the record of what is fitted stays with the hardware rather than in a logbook.

Longer Life
A Smart Cap runs for one year from the date it is first put into service. The meter counts down from initialisation on its own and puts an on-screen message up once the cap has expired.

Aligned Right Every Time
An alignment key on the cap matches a guide on the probe body, so the cap can only seat one way. Press it on until it snaps home; once fitted it should stay on until a replacement is due.
