Aerospring Wheelbase For Planters

This is a highly accurate 3-IN-1 PH, EC & Temp meter. Equipped with a backlit LCD, the Tri-meter enables users to conveniently test and measure water quality. As pH value varies with temperature, this pH meter is equipped with Automatic Temperature Compensation (ATC), so you needn't worry about the effect of temperature change on pH level. The pH value will automatically be adjusted in temperatures between 0 - 50 °C (32 - 122 °F).
