HI-PHCAREKIT pH Electrode Maintenance Kit
HI-PHCAREKIT:
The pH 4.01 buffer in a 230ml bottle is one of the most commonly used buffer solutions. It is extremely stable and represents the mid-way point in the acid range of the pH scale - ideal for those requiring an accurate acid reading, particularly those working in water purification plants, the food industry, and wherever the pH is expected to be acidic.
pH 7.01 is ideal for those requiring an accurate neutral reading, particularly those working in water purification plants, the food industry, aquatics, and Hydroponics, and wherever the pH is expected to be neutral. Latest Hanna portable and bench microprocessor instruments are calibrated with pH 7.01.
HI-7061m is a general purpose cleaning solution which can be used for a variety of applications. Electrodes become dirty from use and will produce inaccurate results even if they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues which are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly.
At Hanna, we suggest cleaning the bulb and junction of your electrode on a regular basis in our ready-to-use cleaning solutions to ensure that the probe is always clean and to prevent any clogging of the junction.
All cleaning solutions are packaged in an air tight bottle with tamper-proof seal to ensure quality and freshness. All solutions show a batch number and expiry date.
HI-70300m 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 (HI-70300 or HI-80300) before taking measurements. pH 4.01 or pH7.01 buffer solution can be used if storage solution is running low.
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.
Air-tight bottles with tamper-proof seals ensure quality and freshness of storage solution. Each bottle is marked with a batch number and expiry date.
