PH meter is one of the main products of Shanghai Boqiu Instrument Co.
, Ltd.
It is mainly used to measure the pH value of liquid medium.
It can also measure the MV value of ion electric potential with the corresponding ion selective electricity.
The pH meter is widely used in environmental protection, sewage Processing, scientific research, pharmaceutical, fermentation, chemical industry, aquaculture, tap water and other fields
.
The instrument is also the inspection equipment in the QS and HACCP certification of food factories and drinking water factories
.
As a commonly used instrument, there will inevitably be some small problems during use.
The following are common problems in the use of online PH meters and their handling skills, hoping to help newbies! 1.
The number of the online PH meter is beating randomly? Answer: It may indicate that there is leakage at the reference connection, try to wipe the connection terminal with anhydrous alcohol, and keep the humidity of the connection to meet the technical requirements
.
2.
The online PH meter does not display after the power cord is connected to the instrument? Answer: When the power supply is wrongly connected, you can usually smell peculiar smell or see smoke from the instrument
.
3.
The pH/mV of the online pH meter does not change in any solution? Answer: The electric bulb has been ruptured and needs to be replaced
.
The connection between the power and the instrument is disconnected, please check
.
The electric cable is broken inside, please replace or send it back for repair
.
4.
After the online PH meter is connected to the relay control terminal, the power cord is burned when the power is turned on? Answer: The wiring method is wrong, please refer to the (Relay Control Instructions) section
.
5.
The online PH meter feels that the measured value is not accurate? Answer: Take out the battery, clean and calibrate it according to the instructions.
If the calibration cannot be done during the calibration process, please try to change the battery
.
6.
The online PH meter has not changed after performing the special function operation? A: The MODE key is not pressed to execute a cycle after performing a special function operation in pH or ORP mode
.
The correct way to operate the special function is: press and hold the corresponding key of the function to be converted in the power-off state, then turn on the power, wait until the corresponding prompt is displayed, release the key, and then press the menu key in the working mode to execute a cycle
.
Seven, online pH meter electrical response is slow? Answer: When the bulb is covered with dirt and the liquid junction is blocked by dirt, the reaction will be slow, please try to clean it
.
It is normal to be slow in winter
.
8.
The online PH meter has no control signal output? A: Check if the screen is in normal mode
