Introduction

• Also in for a low cost, convenient to useopen source pH meter and worry? We launched a specially designed for theArduino1 controller simulation PH meter, has the characteristics of attachmentis simple, convenient and practical. The onboard power light, BNC interface and XH2.54 interface. Use, will received pH sensor onboard BNC interface, theonboard XH2.54 interface connected to the Arduino1 controller simulation, throughthe program control, you can very convenient measuring the pH of the solution.

• PH sensor electrode using glass electrode and reference electrode togethermolded case not filling type composite electrode, PH meter measuring elementand is used to measure the hydrogen ion activity in aqueous solution, the PHvalue.

• The sensor with thick black boxes, enclosed black high quality rubber cushion,full protection components, not only beautiful and generous. Attached to thecore components - PH electrode manual for proper use convenient user'ssecondary development.

Warm Prompt

     Please use an external switching power supply, make as far as possible close to+ 5.00 V voltage, voltage more exact, the higher the accuracy.Electrodes in each successive need to use the standard buffer solution beforeuse for correction, for a more correct result, the environment temperature at25deg or so, to the best known PH value to be reliable, and its PH value very close tothe measured value of time. If you measure the samples for the acid, please usePH4.00 buffer solution to correction of electrode, if you measure the sample isalkaline, please use the PH9.18 buffer solution on the electrode. Segmentscalibration, just to get a better precision.PH electrode per a pH measurement of different solution, you need to use cleanwater, it is recommended to use di water to clean.

Using the step(1) connect the equipment according to the graphic way, namely: the pHelectrode is connected to the pH meter BNC interface circuit board, and thenuse analog cable to connect the pH meter circuit board to the Arduino1 mastercontroller simulation of 0. For Arduino1 master controller power supply, you cansee the pH meter circuit board of the blue light is brighter.(2) for the Arduino1 master controller burning sample code.(3) the pH electrode inserted into the pH value of 7.00 of the standardsolution, or directly short BNC interface of two input, open the Arduino1 IDEserial port monitor, you can see the print out of pH value, the error does notexceed 0.3. Record at this point the value of the printed and then comparedwith 7.00, the difference between Offset changes to the program in place. Toprint out the pH value of 6.88, for example, the difference of 0.12, is in thesample program # define Offset to 0.00 # define Offset of 0.12.(4) insert the pH electrode in the pH value of 4.00 calibration fluid, wait aminute later, gain adjustment potentiometer, make as far as possible to printout the pH of the stable at about 4.00. Meanwhile, acid calibration has beencompleted, you can test the pH of the acidic solution.Note: other measurement solution, must wash the electrodes.(5) depend on the linear characteristic of pH electrode itself, through theabove calibration, can directly measure the pH of the alkaline solution, but ifyou want to get a better precision, recommends calibration. Alkaline period ofcalibration using standard solution pH value of 9.18, is also to adjust gainpotentiometer, stable at about 9.18. After calibration, right now you canmeasure the pH of the alkaline solution.
