Ph pen

[ScorpionX86]

Can a faulty Ph pen be Repaired?or die die must replace?

Depends on the fault... need more details for meaningful help.

Note that all pH pens need to be calibrated every 1-3 months to maintain the precision.
Some models like Dymax allow you to change the pH probe only so you do not need to replace the whole pen.

Hi Scorpion,

just want to check is the pH pen effective to determine pH or rather accurate ? Or rather anyone knows what is the best method to determine tank ph ?

pH pens are the most convenient way to get readings.

But unless you're intending to spend more than $100 - $200, a good quality $20 - $30 test kit will give you more accurate results.
