The corresponding 4-20 mA analog output can also be shown. Versatile Hookup Capability PRO-series transmitters can be wired in a two, three, or four-wire hookup arrangement to meet your application requirement. Compact Size and NEMA 4X Universal Mounting Versatile Sensor Capability The compact PRO-series transmitter can be panel, wall, pipe, or integral sensor mounted. The PRO-P3 transmitter can be used with any GLI Differential Technique pH or ORP sensor, or any conventional combination pH or ORP electrode. Automatic temperature compensation is provided when using NTC 300 ohm thermistor, Pt 1000 RTD, or Pt 100 RTD temperature elements. For applications requiring fixed temperature compensation, the PRO-P3 can be manually set to a desired temperature. Multiple Language Capability All screens can be selected for display in English or Spanish. Different languages such as French or German may also be substituted. Simple Interactive Diagnostics “Menu-guided” Operation Built-in diagnostics continuously test transmitter and sensor operation. The simple keypad and logical menu structure make this transmitter easy to use. OEM Versions Available Passcode-protected Access PRO-series transmitters can be packaged or configured to accommodate OEM-specific needs. For security, use the passcode feature to restrict configuration and calibration settings to only authorized personnel. Isolated 4-20 mA Output The isolated 4-20 mA analog output can represent the measured pH or temperature (or ORP). During calibration, the analog output is automatically held at the last measured value and, upon completion, returned to its active state. Certified Compliant to European Community Standards Both analog output values are shown together on one screen.In the interest of improving and updating its equipment, Hach Company reserves the right to alter specifications Probes 8 Pages Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates.http://anadolumatbaa42.com/genelresimler/garrison-carbon-monoxide-detector-manual-kn-copp-3.xml

The probe is designed for fast, accurate pH measurement in wastewater, drinking water, and general field applications. Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal. Measuring ranges pH: -2.00 to 19.99 Temperature compensation Automatic thanks to the Pt 1000 built-in in the probes.Please contact us to arrange this for you. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. In wastewater treatment, pH is regulated as part of discharge permitting and many treatment processes are pH dependent. In biotechnology, pH must be closely monitored during the production of immunoassay solutions. These are just a few of the many applications in which the pH measurement is a valuable tool. Who doesn’t? You deserve good data, but for good pH data you need to calibrate. You need to calibrate well and calibrate often. Since both of these can change over time, frequent calibration is necessary. More frequent calibration is recommended when measuring in heavily contaminated, low-ion, strongly acidic, and high temperature solutions.http://coracconstrucciones.com/dleyes/admin/fotos/garrison-carbon-monoxide-detector-manual.xml

This holds true whether the probe is being used or not. The lot code will determine the age of your pH probe. A lot code is two numbers then a letter.Always check the meter and electrode manuals for calibration and routine maintenance information. This can result in permanent damage to the electrode. Also, it is preferable that pH electrodes be chemically, rather than mechanically, cleaned. Vinegar soaking may require a longer period of soaking to remove hard deposits. Glass electrodes are also commonly refillable. If you find your pH probe has dried out, it may need to be replaced. Storing in pH 4 buffer helps prevent growth or buildup in the storage environment that could coat the sensor and affect your readings. Recommendations regarding the storage of a pH electrode vary based on the length of time the electrode will be stored, as well as the electrode type. Regardless of the length of storage or the electrode type, no pH electrode should be allowed to dry out. Also, pH electrodes should never be stored in DI water. Use pH 4 buffer as it also helps eliminate leaching of electrolyte. If this is the case, and your pH electrode has been allowed to dry out, soaking the electrode in a suitable solution might successfully rehydrate it. Both lab and field electrodes should be soaked for at least 24 hours and recalibrated afterwards. If electrode performance is poor after rehydration and subsequent cleaning procedures are unsuccessful, the electrode will likely need to be replaced. The accuracy of the pH data is dependent on the accuracy of the temperature data. The thermistor is not able to be calibrated so if your temperature sensor is no longer good, you will need to replace the electrode. Once buffers are used for calibration, they are assumed contaminated and should not be used again. Reusing buffers can lead to slow responding pH probe performance or the inability to calibrate at all.

This reuse can also make it difficult to determine whether the probe or the buffers are causing the pH calibration failure. Carbon dioxide in the air can change the pH of basic buffer solutions, so basic buffer bottles should only briefly be opened. Use opened containers of buffer as soon as possible. The pH buffers used should differ by at least two pH units and should bracket the expected in-situ pH conditions. Unless the sample is expected to be above pH 7, basic buffers should not be used, as their pH value quickly changes by absorbing CO 2. Asymmetry and slope are determined for both 2- and 3-point calibrations. The range of use of 1-point calibrations is limited and should only be completed with pH 7 buffer. The pH value obtained can be used to compare to previous results, but is not an absolute value. For example, rinse with pH 10 buffer if you have finished calibrating to pH 7 and are preparing to calibrate to pH 10. Alternatively, the electrode can be rinsed with DI water and carefully dabbed dry. The calibration container should always be clean. The size of the calibration container typically doesn’t matter, as long as the electrode junction is immersed. The theoretical zero point is, not surprisingly, 0 mV. This is true because the reference electrode is typically in a solution of electrolyte that has a pH of 7. A new electrode will have an asymmetry potential that is typically only a few mV if it has been carefully prepared. It is a good idea to consult the user manual. The user manual will also supply the proper process to do this task because this process can vary depending on the instrument. (User manuals can be found in our Resource Library ) This response time can depend on the age and cleanliness of your probe and a slow response suggests the electrode is old or dirty. Electrodes will generally last 12-18 months, even if they are not being used.

Electrodes will age faster if used in extreme operating conditions (strong acids, high temperatures), resulting in a slower electrode response, change in slope, and change in asymmetry (i.e. zero point). Not all instruments have this capability, but some instruments do. It is highly likely you will not collect any usable pH data if an out-of range calibration is accepted. Replace the electrolyte if it has become contaminated. Depending on the model, the refill opening is either a slider (left image) or a stopper (right image). The refilling opening must always be open during calibration and measurement. The temperature sensor must also be in solution in order to accurately compensate pH for temperature. Also, the pH values of buffers in a buffer set can vary from one set to another. Modern pH meters automatically adjust for the respective temperature profile once the buffer set used has been correctly set. So if I were to use a pH meter probe on tissue samples, I should probably clean it with some sort of bleach before using it again.I just had a problem with my pH meter, and your tips helped me solve it. I am really grateful.Reply Add a comment Name Learn more about Xylem and Xylem Analytics. We use cookies and beacons to improve your experience on our site.
