Digital pH Meters Product Description

The EcoSense pH10A pen-style digital pH meters provide the ultimate feature set over similar competitive models. The digital pH meters feature an easy-to-use graphic interface, simple one-hand operation, memory, and low cost of ownership over the life of the product. The easy, user-replaceable digital pH meter’s electrode ensures the instrument is always ready for use. Featuring advanced microprocessor technology, the EcoSense digital pH meters offer automatic calibration (to values of 4, 7, or 10.01) and options such as automatic temperature compensation (ATC). The pH10A pen-style digital pH meters are IP67 rated for wet environments. The digital pH meter can save up to 50 readings even if the power is lost. The digital pH meter also has data hold, auto shut-off, and low battery features. The pH10A digital pH meters are ideal for aquaculture/aquariums, surface water, agriculture/hydroponics, pools/spas, and wastewater applications. This line of digital pH meters comes with a one year instrument warranty and a six-month electrode warranty.
