Product information

Healthy fish thanks to ideal pH value
The pH value defines the acidity of the water. It needs to be constantly checked and adjusted as necessary to maintain the health of the fish and plants. The correct pH value depends on the fish stock of the aquarium. The wrong pH value can cause stress and diseases.

Technical information:
Precision solenoid valve.
Separate pH value + temperature sensors.
Modern graphic display.
Sensor check during each calibration.
Error diagnosis after failed calibration.
Permanent display: pH actual/set value, sensor voltage, temperature, calibration reminder in days/hours, valve status, precision of measurement.
Set point adjustment: freely selectable or automatic calculation by means of auto pH.
Automatic temperature compensation during measuring and calibration.
Hysteresis freely selectable (upper and lower deviation from switching point).
Password key lock.
Alarm function pH (alarm range).
Alarm function temperature (range and set point alarm).
Selectable valve status.
Language selection: D/BG/F/NL/I/DK/E/P.
Reset function.

Universal power unit suitable for all common mains voltages worldwide. Electrode to be separately purchased to make sure that user always gets a brand-new sensor. The electrode needs to be replaced about once a year.

Technical Data

FAQ
Why does the controller permanently indicate a too high/low pH value? And why doesn’t the calibration work although the sensor is new?

The cause can probably be fixed quite easily. The protective cap of the pH sensor needs to be removed before insertion into the aquarium / before the calibration, to carry out control / calibration correctly. The protective cap serves as storage and “reactivation” of the sensor with the storage liquid. It has to be removed for use inside the aquarium and during the calibration because no water from outside can pass through.

If the controller still displays an error, even after the removal of the protective cap, please read the FAQ with the several error messages in detail.

How does the JBL pH-Control recognise a “bad“ sensor?

The pH sensor transmits a voltage to the measuring device, which convert the voltage into the pH value.
This voltage does NOT remain constant throughout the service life of the sensor! It needs to be calibrated regularly. The device is thus informed about the age-related change in voltage and can display reliable values again.
The calibration takes place at pH 7 and pH 4.
At pH 7 a new sensor transmits a voltage of 0 mV (+/- a few mV) to the measuring device. The more the voltage at pH 7 deviates from 0, the older the sensor is. The deviation can occur at + or -. At a deviation of more than +40 or -40 mV the device rejects the sensor.
The error message OFFSET appears.
NOTE: The same error message appears if you accidentally begin to calibrate at 4!!
At pH 4 the sensor transmits a voltage of about +186 mV (when 7 is at 0 mV). This means that between the single steps (4-5; 5-6 and 6-7) there is in each case a difference of about 62 mV. The smaller this difference, the older the sensor. With differences below 30 mV the device rejects the sensor.
The error message DELTAV appears.
NOTE: The same error message also appears, when you accidentally calibrate twice at 7!!

IMPORTANT: Rejected sensors can often be brought “back into operation” if you soak them intensively in storage solutions (for several days)!

What does INSTAB mean in the display of the JBL pH Control 12 V ?

The message INSTAB indicates: instable sensor voltage: the sensor tip is dirty, the electrolyte has leaked from the sensor, the sensor tip is damaged.
Remedy: Clean the sensor head (see the respective instruction), put the sensor into the storage solution for 24 hours and repeat the calibration. If this does not work the sensor is defective and should be replaced.

JBL pH-Control, JBL pH-Sensor: What deviations are common when calibrating and how do they correlate with the temperature?

It is difficult to give a precise answer without information about the sensor, particularly the age of the sensor. Good sensors have deviations in the range from 0.02 to 0.05 pH levels when calibrating.

The input voltage differs for each electrode, as each electrode has its own individual properties. For the majority of our electrodes, it is between -30 and +30 mV at pH 7.

Both input voltages (pH 7 and pH 4) are important when assessing the quality of an electrode. The greater the difference between these two values, the better the electrode and the precision of the measurement and control. The differences should be over 140-150 mV.

The temperature sensor should always be used during calibration. The pH level varies according to temperature, so that it is always best to measure the pH level with temperature compensation.

What does OFFSET mean in the display of the JBL pH Control 12 V ?

The message OFFSET indicates: sensor voltage at pH 7.00 is outside the limit value, the sensor is too old, the cable is defective or no sensor is connected.

Remedy: Check the sensor cable for any signs of damage and repeat the calibration. If this does not work, replace the sensor and calibrate again.

Fertilization is not just fertilization Part 1

Unlike in natural waters, aquariums with fish mostly have a surplus of nutrients caused by feeding and the resulting fish excrement. Thus nitrates and phosphates in large (often too large!) quantities are available for the plants.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails).

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).
