American Marine Pin Point PH Monitor

[sunny03]

Hi Guys

Got a Ph monitor however the the reading kept on jumping sometimne goes to 7 and even as high as 9 ( no change in lighting and did not add any stuff into the tank

wat can i do to stop the reading jumping so fast

Bro,

izit calibrated properly? If the probe is not damaged and is in good working condition, maybe the pH of your tank is really swinging... but IMO, I tink the probe spoilt...

[blueheaven]

Did your probe change position?

[sunny03]

Nope did not change the probe position i place it in my sump tank

[blueheaven]

Then it is probably a problem with the probe

[Tigger]

Why not bring over to my place and run for 1 hr to see it swing? Just try out lah, u never know.

[Melvyn Tan]

Can bring over to my place thereafter to conclude

From what I read, try do the testing in a dark room. Either its too sensitive to light due to its quality or lifespan.

pH probes are not sensitive to light.

[sunny03]

it is due to LOW batt

it is due to LOW batt

usually the case.. we expect the unit to run forever and we forget about the battery
