Hanna HI70300M Offers

It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used, never store an electrode in distilled deionized water. This solution is specially formulated to minimize microbial growth and to prevent any diffusion/osmotic effects between the solution and inner reference electrolyte. Storing your pH and ORP electrodes in a storage solution will also keep the junction clear. Soak the electrodes in HI70300M solution for at least one hour before taking measurements. Manufactured specially for pH and ORP electrodes, hanna's solutions have an expiration date of 5 years. The expiration date and lot number is clearly marked on the bottle.
