Why does calibration fail? You used the wrong water for calibration. Please use purified water for calibration, not mineral water or natural drinking water.
6 in 1 Drinking Water Analyzer TDS Meter, TOC Meter, COD Meter, UV275 Meter, Electric Conductivity Meter & Temperature Meter Water Testing Kit features the most updated technology with high precision. Wide test range makes it fits multiple uses, tap water, well water, water purified by drinking fountains, bottled water, ground water, surface water (not sewage) and other drinking water
COD & TOC COD & TOC refers to organic pollution and other hazardous substances. These types of tests can usually only be done in specialized laboratories, but our high end water testing pens can perform these functions. Normally TDS can only detect minerals and other dissolved solids in the water, and the TDS value alone cannot be used as a criterion for judging the quality of the water. In order to ensure the quality of water, we have made our laboratory equipment into a high-end tester for home, Hiking, Camping, Travel, and Emergency Preparedness
Laboratory Grade Probes The probe is a laboratory spectroscopy probe, the device power on prompts “calibrate within a week”, in order to facilitate laboratory use scenarios. For less rigorous daily home use or outdoor travel use, weekly calibration is not required. After a period of use, calibration can be performed using pure water（ Use purified water for calibration, not mineral water or natural drinking water）
Water Quality Scoring There are 4 levels of water quality Excellent , Good, Average and Poor.Allows one button operation, just turn it on and put meter into water, you can get stable and accurate data in seconds.With our 6 parameters all-round water quality meter to ensure healthy water quality and environmentally friendly water, to avoid the absorption of harmful substances and accumulation in the body
