• Compact and Easy to Carry: The drinking water tester, compact size, convenient to test the water quality of your home drinking water, well water, pond water, lake water and whether you need to change your outdoor water filter bottle cartridge at any time
• Simple Calibration: One button calibration, no need for tedious calibration powder, simply place it in puried or distilled water (no mineral or natural drinking water please, or calibration will fail), then select the calibration button and wait 3 seconds
