No I don't have a meter.
Hanna makes a great meter that you will not find in a grow shop usually. It is a constant monitor so no batteries. Measures temp, ppm, microsiemens, ph, and is only 119.95. Call Hanna for the local distributor. The model is the Hanna 9044 and it is the only meter I trust.
One love
