Key Features

• Laboratory-grade Water Testing: COD and TOC refer to levels of organic pollutants and other harmful substances that can only be measured by specialized laboratories, and we've improved them into high-end testers for home, hiking, camping, travel, and more
• 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
• Calibrated for Different Situations: The probe is a laboratory grade spectroscopy probe, so the device is powered on with a prompt "calibrate within a week". Does not need to be calibrated as often for less stringent daily home use or outdoor travel use
• Water Quality Visualization: The color of the display will be divided into 4 grades of excellent, good, medium and poor water quality, allowing you to intuitively understand the quality of the sample water, to ensure that you drink safe and secure water
