pH meter PCE-228
the pH meter measures for pH, Redox and temperature /
SD memory card (1 ... 16 GB), measured values are stored in an Excel file /
large display / RS-232 interface and optional software for the PC
The PCE-228 pH meter is an easy-to-use handheld device for measuring pH, mV and °C. With the PCE-228 pH meter, both temperature and pH values can be directly stored onto a SD card (in Excel format), or transferred to a PC through an RS-232 interface. An optional software and data cable for the PCE-228 pH meter are available as optional accessories to transfer data to a computer. Temperature compensation in the PCE-228 pH meter can be done manually or automatically by way of the temperature sensor which is included.
The pH meter has two calibration points. The calibration can be done with the trimmer on the side of the device which is protected under a cover. With this combined device, the user can determine pH value, temperature or Redox potency (ORP). For the latter measurement parameter, a Redox electrode must be ordered separately from the PCE-228 pH meter. We recommend the ORP-14 electrode. The pH meter is powered by a 9V battery which is included.
Fish breeding is challenging occupation which requires a lot of careful maintenance from its owner. It is different from just some water body or aquarium where certain amount of fish may be present. Fish farm may be created artificially, but may be also a part of some natural water body, made in the lake, pond or similar. Correct pH level and chemical characteristics of the water is of vital importance in fish farming, since this determines the health and reproductivity of the fish. Very low and very high pH levels are dangerous in fish farming, because the limited area does not allow fish to swim away, out of the inappropriate for them medium.
Most suitable conditions for quick growth should be between 6 to 9, and whenever the values go beyond these limits, quick measures should be taken to change the pH level. This is achieved by application of corresponding chemical elements, good filtrating and cleaning systems. In fish breeding it is important to remember that fish as well as breathing, also produce certain waste which gets directly into the water where they are bred. From the one side, the farmer is interested in high concertation of fish in the farm, but from the other, he needs to care about sufficient cleaning, since high concentration of ammonia is a very unfavorable element which may cause toxic influence. Carbon dioxide is one of the elements which has a tendency to increase in fish ponds, since fish and plants which may occur in the pond, also “breathe” and this problem cannot be left unattended, because even within one day the pH level may dramatically change. To keep the fish farm under permanent control, application of the pH meter is the best solution. The sensor which can be immersed into water a few times per day, provides accurate information about the correct condition of the water, pH level, oxygen, presence of harmful elements in the water, changes in temperature and water composition.
