Product information

Healthy fish thanks to ideal pH value
The acidity defines the pH value 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
Incl. temperature sensors, modern graphic display with touchpad, 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, yysteresis 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/EN/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.

FAQ
What is the master password to unlock the keylock on the pH-Control Touch?

The password to unlock the keylock is “7422“. A printing error caused another code to appear in some instructions. We have since corrected this.

What pH Control interface is suitable for the pH sensor?

A BNC connector is needed.

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 deviations during the calibration are usual and how are they connected to 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 sensor, as each sensor has its own individual properties. For the majority of our sensors, 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 a sensor. The greater the difference between these two values, the better the sensor 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. The deviation is between 20 and 30 °C, 0.17 pH levels, and the relationship is nonlinear.

What does DELTAV mean in the display?

This message indicates that the potential difference per full pH unit is smaller than 30 mV. The pH sensor is either too old, defective or was accidentally calibrated twice with the same buffer solution.

Remedy: Repeat the calibration and take care to use the buffer solution correctly. If this does not work, connect a new sensor and calibrate again.
