Pro pH Monitor & Controller MC122

Pro pH Monitor & Controller MC122

Plants require CO2 during the day when the lights are on and O2 at night when the lights are off for respiration. Th SMS122 pH controller enables you to automate your dosing of CO2 and ensures that the plants of your aquarium are always healthy. The meters are supplied with a plug socket to connect the solenoid valve.
Range: 0.0 to 14.0 pH

Resolution: 0.1 pH

Accuracy (@ 25degrees Celsius): +/- 0.2 pH

Set point range: 5.5 to 9.5 pH

Alarm: active when reading is higher than set point

Dosing contact: 1 power plug for CO2 dosing

pH Electrode: MA911B/2 (included)

Use and Care
pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.

Sensing bulb
The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes.

Reference junction
The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function.

You can extend the life of your pH electrode in the following ways.

Storage
The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.

Store the pH probe in storage solution MA9015. Only use tap water short-term if MA9015 is not immediately available and NEVER store in distilled Water (DI) or Reverse Osmosis (RO) water. This will damage the sensitivity of the probe.

This best way to store the probe is with the probe’s cap filled with MA9015 Storage Solution and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.

Cleaning

Residue from the sample can impact the sensitivity of the sensing bulb and block the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking the probe in MA9016 Cleaning Solution for about 20 minutes.

Calibration
The pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.
