Product Code #HI70300L

HI-70300L is a storage solution prepared with reagent grade chemicals which can be used to ensure maximum performance of your pH and ORP electrodes.

After cleaning your electrode with one of our wide range of cleaning solutions, rinse with tap water, then soak the electrode in Hanna specially formulated Storage Solution before taking measurements. 

Between measurements, storage solutions minimise microbial growth and prevent any effects of diffusion and Osmosis, as well as keeping the sensor tip and reference junction hydrated and clear – all important for an optimum response time and measurement. 

Each bottle is marked with a batch number and expiry date. 

Please note: pH or Oxide Reduction Potential (ORP) electrodes should never be stored in distilled or deionised water as it will shorten the life of the sensor.
