The waterproof/submersible Mini-PH-Electrode S-15 is a very sensitiv, snap and exact pH electrode for the measurement in liquids. Due to its extreme small size you can easily use it where there is little place e.g. below a aquarium cover.

Attention: In opposite to many here offered electrodes which
only may be submerged 25mm this ph electrode may be used
permanently totally under water.

By its BNC connection and 1,6m cable it is compatible to almost all pH measuring instruments such as e.g. all devices offered by us. All necessary cleaning (FL5) and maintenance fluids (FL1) and our pH calibration solutions (FL6) are included in this set.

Cleaning liquid
With our electrodes cleaning liquid (50ml) you can clean pH, Redox and conductance electrode. The electrodes in the aquarium, used for continuous operation, get a biological "lawn" because a bacterial layer forms, which makes the measurement slow-acting and falsifies. For the removal of these linings our cleaning solutions was developed. It contains e.g. pepsin and 0.1 molecular hydrochloric acid (pH ~ 1) to remove proteins, bacteria and algae. We suggest a 30 minute application every 4-6 weeks.

Maintenance
With our 3-mol KCL solution (50ml) you can supplement the diffused liquid. This is of crucial importance for the life span of your electrode. The KCL liquid level in the electrode must always lie over the level of the testing liquid otherwise this could get into the electrode and can destroy it. Likewise the electrode is to be rinsed off after the measurement is done and constantly being stored if not used to keep the thin glass diaphragm always poured. All our electrodes have for this purpose a protective cap which could be filled with a 3-mol KCL solution.

Calibration liquid
3 pack powder for buffer solution (each 1x 4,01/6,86/9,18) for pH meters/pH measuring instruments in a sealed bag. Each bag can be mixed up with 250ml destilled water/permeat to get the desired ph solution. Over 5 years durable.
