PH-907  portable PH  INSTRUCTION

一協同控製、           Panel instruction

l        ON/OFF ： power switch

l        MODE ： function switch，

Repeating：PH →MV→ TEMP  every press

l        CALIB  ： 7.00 calibration （6.86）

l        SLOP   ： 4.00 calibration （9.18品質、10.01）

l        TEMP   ：  temp compensation manually

二利用好、           Easy to operate

1、Put the sensor in water , Turn the power on ,and LCD display current PH value ,if you need to calibrate , please check the calibration part of the manual. Wait for the reading to stabilize. It needs a few minutes to equalize the temp and all the condition .

2解決問題、  Change a ORP sensor if you want to measure ORP in a solution ,THEN press the MODE key when you’ve changed your sensor系列。

3、  For Temp compensation , you can easily turn the TEMP knob to the temp in witch the solution is相互配合。

三空間載體、           PH Calibration

1、Put the clean PH sensor into buffer 7.00相對簡便，a few agitation重要組成部分，wait for the reading to stabilize（suggest at least 5mins），turn CALIB knob to make the value reach 7.00 steadily合作。Recommend tuning slowly.

2勃勃生機、Wash the sensor with distilled water and wipe it with soft tissue助力各業。

3、Put the clean PH sensor into buffer 4.00（or 9 .18）提供有力支撐， agitate a little應用，wait for the reading to stabilize（suggest at least 5mins），turn CALIB knob to make the value reach 4.00（or 9.18） steadily品率。

4相貫通、You may repeat the calibration process for 2-3 times for accuracy。

NOTE：1積極影響、When calibrate ORP sensor please select the right ORP standard自動化方案。

              2  pH sensor ‘s Temp range is  0-80℃

              3、PH value is a parameter related to Temp, for accurate measure temp compensation is necessary . 

4工藝技術、storage for a long time ,such as weeks or months ,the sensor should be cleaned sufficiently

BASIC CON：suitcase效率，9V battery ，combination PH sensor近年來，buffer 7.00and4.00講道理， manual。
