Informace o produktu

Zdravé ryby díky optimální hodnotě pH
Kyselost vody se stanovuje hodnotou pH. Pro zdraví ryb a rostlin je nutné ji neustále kontrolovat a upravovat. Správná hodnota pH závisí na vysazených rybách, nesprávná hodnota pH může být příčinou stresu a nemocí u ryb.

Jednoduché připojení
pH elektroda se spojí BNC přípojkou s příslušným měřicím a ovládacím zařízením.
BEZPEČNOST
Elektroda byla zkontrolována individuálním testem a měla by být po cca 2 letech vyměněna. Je vybavena ochrannou krytkou naplněnou uchovávací kapalinou.

FAQ
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 does the message INSTAB mean?

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.

Do you need to unscrew the screw connection of the temperature sensor, before you can use it?

No, the pH sensor is meant. It is located in a protective cap which is filled with a storage solution. Before the calibration the pH sensor needs to be taken out of this protective cap by loosening the screw connection and to be immersed, without the cap (and storage solution), into the aquarium water.

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.

Why is carbon dioxide (CO2) the most important plant nutrient in the aquarium?

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.
