Meters for pH and Conductivity

Many different meters are available from Esoteric Hydroponics. There are cheap digital meters such as Eutech and we also stock the amazing Conductivity Truncheon and pH Wand from New Zealand which use flashing LEDs to show the CF or pH reading. These are accurate and reliable and cannot be too highly recommended.

They also carry a full two year warranty which is quite remarkable for such sensitive instruments. Esoteric Hydroponics also stock Buffers and Standards. PH buffers are liquids of a known pH, usually 7, which can easily be used to check and correct the accuracy of your pH meter. CF Standards are solutions of a known conductivity which are used to calibrate your conductivity meter.
