PH, conductivity and temperature reader all in one
 
Bluelab Combo Meter is a portable pH, conductivity (EC / ppm) and temperature meter all in one. The Bluelab combo meter has two probes, a Bluelab pH probe and a Bluelab conductivity / temperature probe. When taking a reading, simply place them in the solution and the selected reading is displayed on the screen. Since the Bluelab Combo Meter is portable and does not require a power supply to operate, it can be used anywhere and anytime to help you manage the daily needs of your crops. Calibrating the pH probe is simple as instructions are provided on the back of the meter and the simple one button method makes this one of the easiest meters to use. The pH probe is replaceable so you can use this meter for years to come. The conductivity / temperature probe does not require calibration as it is locked during manufacturing.
