RS485 Communication 7 in 1 Multi-function Water Quality MonitorRS485 Communication Multi-function Water Quality Monitor, can measure PH/ORP/TDS/EC/CF/temperature/humidity, European/American plug, high-precision LCD digital display, 1s fast measurement, easy to use. EC-PPM-CF/ PH-ORP/°C-°F switch, detachable electrode, suitable for Fish tank, Aquarium, Mariculture, Swimming Pool, Drinking water, Laboratory, etc.
P.S :
1.PH value: indicates the strength of acidity and alkalinity in the water.
2. The EC value is used to measure the soluble salt concentration in the solution.
3. TDS: The lower the TDS value, the lower the total dissolved solids content in the water and the purer the water quality.
4.ORP: oxidation reduction potential.5.Orders placed after 21 December 2023 will be delivered with a USB stick containing the installation software as well as an electronic manual and a video guide for installation.

Operation：1.Connect the electrode to the meter.
2.Remove the electrode protective cap
3.Clean the electrode with distilled water and wipe clean the spare water.
4.Turn on the meter by pressing "ON/OFF" button
5.Immerse the electrode in the solution
6.Lightly shake the electrode, read the testing when the numeric stabilized.Press "C/'F" to convert temperature . Press the "MODE" button under the left screen to convert different mode between EC.ppm and CF .Press the "MODE"button under the middle screen to convert different mode between pH and ORP
7.Press the "ON/OFF" button to shut off the instrument.Clean the electrode with pure water, cover the electrode protective capCalibration：pH MODE Calibration：1.The pH meter must be re-calibrated before using.
2.Turn on the meter by pressing ON/OFF button
3.Dissolve each buffer solution into 3 cups which is filled with 250ml distilled water
4.Press "MODE" button on "pH/ORP" screen to shift to pH mode
5.Immerse the electrode into the pH 6.86 solution.(under the temperature of 25℃)Press the "CAL" (calibration) button for 5 seconds and release.
-Display will start flashing 6.86
-Wait until the display stops flashing
Clean the electrode with distilled water and dry it with filter paper.
6.Immerse the electrode into pH 4.00 solution，
-Press "CAL" button for 5 seconds , 6.86 is flashing
-Short fast press "CAL" button again .4.00 is flashing
-Wait until display stops flashing.
Clean and dry the electrode with distilled water as before.
7.Test calibration by inserting electrode into the standard buffer solution,gently stir electrode until the screen display stabilizes. (if necessary repeat the calibration procedure)
8.Clean the electrode and replace the protective cap.EC/PPM/CF Mode calibration:1.Turn the meter on
2.mmerse the electrode into 1413uS/cmWait until the testing stable. Press "CAL" button upper right corner of EC/PPM/CF for long time
3.Screen displays the testing values. Press up narrow to increase digits. Press down narrow to reduce digits until the showing value is 1413.
4.1413 flash 3 times and finish EC calibration. If you need calibrate other standard values, the operation is same.ORP mode calibration:1. Turn on the meter by pressing ON/OFF button.
2. Press "MODE" button on "pH/ORP" screen to shift to ORP mode.
3.Immerse the electrode into 256 mV standard solution Press "CAL "button on right top corner of the pH/ORP screen for 5S.
4.Screen flash the testing values .Press up narrow to increase digits
Press down narrow to reduce digits until the showing digits is 256mV.
5.256mV flash 3 times and finish calibration
6.Clean the electrode and replace the protective cap.
7.If nessaray, please recalibrate ORP again
Note:
Recalibration is required in the following conditions:
-Lengthy periods of inactivity
-Very frequent use
-The testing accuracy requirement is very high.
-The "CAL" button was pushed in the air or wrong solution.How to maintain the product？1.Always replace protective cap after using digital metero keep electrode from drying out due to prolonged exposure to air, which leads to slow unstable readings. If electrode has been dried out, immerse it into 3.3mol KCL standard solution for few hours.
2.Battery: When the battery is low, the battery symbol will shine Please connect the power supply to charge the battery.Usually need 5 hours for recharaing the battery
