HM Digital AP-1
AquaPro Water Quality Tester (TDS) and Temperature

Quality Product ~ Designed in USA and Korea

Measure and Monitor Total Dissolved Solids (TDS) levels for

The United States EPA's Maximum Contaminant Level for Total Dissolver Solids (TDS) for human consumption is 500ppm.

HM Digital introduces its new AquaPro series, a line of handheld TDS/EC meters with a sleek design that's perfect for today's modern kitchen. The AquaPro digital water testers are the next generation for today's tech-savvy and health-conscience consumer.

Measures total dissolved solids (TDS) and temperature.

Auto-off function, data-hold function and low-battery indicator.

Display: large and easy-to-read LCD screen includes simultaneous temperature reading.

Factory Calibrated: The AquaPro is calibrated with a 342 ppm NaCl solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.

Resolution: 1 ppm; Temp. resolution is 0.1 °C/F

Calibration: Digital calibration by push button.

Power source: 1 x 3V button cell (included) (model CR2032)

Dimensions: 15 x 2.8 x 1.3 cm (5.9 x 1.1 x .5 inches)
