HANNA

The Hanna HI-70300M Storage Solution is designed for optimal maintenance of pH and ORP electrodes. It prevents drying, reduces bacterial growth, and maintains necessary hydration for accurate measurements. Packaged in a 230 mL, tamper-proof sealed bottle for freshness, it's marked with batch numbers and expiry dates for quality assurance. Avoid using distilled or deionized water for storage, as it shortens electrode lifespan.

Hanna's electronic pH meter is a precision instrument that easily and accurately measures pH. It runs on batteries and is very easy to set up. To operate you simply press the "ON" button and dip the meter into the solution you want to measure.

Ideal for swimming pools, spas and aquariums.

Chlorine is the most commonly used water disinfectant and by monitoring chlorine regularly and accurately, serious health and safety risks can be avoided.
