Product Description


Brief introduction:

This 2-in 1 Combo pH & TDS mini tester helps you monitor and measure the pH level and the Total Dissolved Solids (TDS) of a solution. It is more convenient to use with its big LCD display and the pH and TDS electrode are separated, making the measurement more accurate. Since pH value varies with temperature, this pH monitor is equipped with Automatic Temperature Compensation (ATC), so temperature change can't hardly effect on pH level. pH value will be automatically adjusted in temperature between 0 ~ 50 °C. Both pH and TDS are important parameter to keep track the pollution level in water. Thus this meter is a very useful tool for environmental monitoring, laboratories, hydroponics, aquariums, swimming pools, spas and food processing etc.
