Conductivity Meters are ideal for many different water applications like reverse osmosis water purity, wastewater regulation, aquaculture, more. The large LCD display lets you quickly see the conductivity reading along with the temperature of the water. Along with a waterproof housing and the large buttons, you can use the meter with wet hands, or even in extremely humid environments.
