PHT-027multi-parameter Water Quality Monitor

This monitoris a member ofthe line of qualitymonitors availablefrom ours.
The ContinuousMonitor Seriesfeature microprocessor technology, which gives itmany reliable,user-friendly features.These monitors were designed forlong-term low-maintenance use, justplug inthe  AC adapter, calibrate andthe unit is ready for continuous monitoring. Itincludes therechargeable batteries. It can insure working when powercut.

Operating Information
1. Connectthe power adaptor tothe power supply outlet.
2. Connectthe pH or ORP electrode tothe probe inset of the instrument.Remove theprotective cap.
3. Turn onthe meter .
4. Immersethe electrode in the solution tobe tested.Stir gentlyand wait for the reading to stabilize.
5. Pressthe " / " key , choice the  / for measuring. Press the"EC/CF/ppm " key, choice inturn show EC, CF , TDS for measuring.
6. Whenyou connectthe ORP electrode, Pleasepress the"MV" key . It will showthe ORP value.
7.  After use,turn off the meter . Rinse the electrode with tapwater to minimize contamination.Replace theprotective cap.

Calibration
1.PH Calibration
Pour asmall quantityof pH6.86,pH4.01and pH9.18solution into clean beakers.
For aparticularly accuratecalibration, itis advised to use two beakers for each buffer solution; the first is to be usedfor rinsing the electrode,the second is to be usedfor the calibration. Inthis way , the risks of contaminating thebuffer solution are reducedto a minimum.Connect thepower adaptor.Turn on the meter .The calibrationof theinstrument's pH range is now complete.
Immerse the ph electrodein pH 6.86 buffer solution, andgently shakeit.Allow thereading to stabilize andwith thesupplied screwdriver, adjust the "pH6.86" calibration trimmerto read "6.86"pH. Rinse the electrode with distilledwater,and suckit with filter-paper.Immerse the ph electrodein pH4.01 buffer solution, and gentlyshake it.Allow thereading to stabilize andwith thesupplied screwdriver, adjust the "pH4.01" calibration trimmerto read "4.01"pH. Rinse the electrode with distilledwater,and suckit with filter-paper.Immerse the ph electrodepH9.18 buffer solution untilthe display shows"9.18".

2.EC CF ppm Calibration
Press the" EC/CF/ppm " key . Choice the "EC" for operating. Immerse the meter in 12880 s/cm(12.88EC) calibrationsolution.
Immerse the meter in1413 s/cm(1.41EC) calibration solution.  

Important:Notice
Stir gentlythe meter when using.Don't letsome blebon theelectrode.In case of abnormalphenomena suchas highmeasured deviation,blinking measuredvalue, nozero resetting,etc, pleaseimmerse the electrode inalcohol forcleaning.If the protection caphas beenwithout electrolyte,or ifthe electrode has notbeen usedfor a long time, the electrode must bereactivated by leaving it for several hours ina beakercontaining normaltap water .When withoutusing poweradaptor,If the meter cannot beswitched on
or thedisplay fades.Please connectthe power adaptor tothe power supply outlet.It will charge upthe rechargeable battery. Andit also works on.

Warranty
These instrumentsare warrantedfrom all defects inmaterial and manufacturing fora periodof oneyear fromthe date of purchase.
If during this period, the repair or thereplacement of parts isrequired where thedamage isnot dueto negligence or erroneousoperation by user,please returnthe parts to either dealer orour offices, and the repair will be effected free of charge.
Allow thereading to stabilize andwith asmall screwdriverturn the CAL calibration trimmeruntil thedisplay shows"12.88EC". Rinse the electrode withdistilled water, and suck itwith filter-paper. until the display shows "1413(1.41EC)".The instrument'srange must be re-calibratedwhenever:The electrodehas beenused(laid) forlong time from the last calibration.The electrodehas beenused inparticularly taxingconditions.The utmostaccuracy isrequired.
