Dear robotshop,
I want to buy sensor **Analog PH meter pro - Product Code : RB-Dfr-639 **to measure PH in aquarium. But I want to measure 24hour / day for long - term.
Can it do that ?
How long it can measure ? (maximum day)
Can it shipping to Vietnam? How long it can delivery ?
Thank you!

According to our supplier:
Long-firing Operation:
SEN0169 supports, while SEN0161 NOT, i.e. you can not immerse SEN0161 in water for Continuous Testing.
Life Span :
In 25 ℃ pure water, you can do continuous testing with them both for work two years, For reference, if put them in turbid, strongly acid and alkali solution, 25℃, the life span would drop to one year (SEN0169), 1 month(or shorter, SEN0161). Temperature, pH, turbidity of the water effect the probe life span a lot.
Waterproof :
You can immerse the whole probe SEN0169 into the water, while you can only immerse the front part of the probe SEN0161, the electrode glass bulb, into water, the rear part, from the white shell to the cable, MUST NOT be under water.
Precautions:
]Before and after use of the pH electrode every time, you need to use (pure)water to clean it./ :m]
]The electrode plug should be kept clean and dry in case of short circuit./ :m]
]Preservation: Electrode reference preservation solution is the 3N KCL solution./ :m]
]Measurement should be avoided staggered pollution between solutions, so as not to affect the accuracy of measurement./ :m]
]Electrode blub or sand core is defiled which will make PTS decline, slow response. So, it should be based on the characteristics of the pollutant, adapted to the cleaning solution, the electrode performance recovery./ :m]
]Electrode when in use, the ceramic sand core and liquid outlet rubber ring should be removed, in order to make salt bridge solution to maintain a certain velocity./ :m]
Thank you for your support.
