I am looking for a good all in one monitor for ph, PPM, Temperature and humidity all in one guage.. Or even one good g age. that shows the temperature/humidity readings and another that shows ph/ppm... I want to be able to glance at it and know what the readings are in my DWC tank... My plan is to mount these to the outside of my tent with the probes in the water or in the tent... I am new and want to have the option of looking at the readings without opening the tent... I have looked at several different monitor/gauges, but can't seem to find what I need... I don't think I need water temperature, just air temperature and humidity... But I do want to be able to glance and know the pH and ppm of the water... Thanks for the help...
