pH Meter


Reviews & Questions

The ETI pH Meter is used to measure the pH of your nutrient solution. These very easy-to-use, efficient meters are simply turned on and the probe is then dipped into your nutrient tank. The display will then show your pH level.

It is essential to calibrate your pH Meter. To do this you will require a bottle of Buffer 7, please note: this meter comes with a small sachet of Buffer 7. You simply dip the meter into the Buffer 7 solution and hold the ‘calibrate button until is says CAL. The pH meter will then re-calibrate the device.
