Envig Digital Drinking Water Tester | TOC, COD, TDS & Temp 4-in-1 | Organic Contamination (Algae, Chemical, VOC etc.) | Lab Grade | Well, Tap, Aquarium & Outdoor Water Quality
- Best Testing Coverage --- With so many things that can be tested in your drinking water, it can be overwhelming and expensive to choose a lab test. Use this water quality meter to give you the direction in a tiered approach. It covers overall contaminant levels not only related to inorganic matters (TDS), but more importantly related to organic matters (pathogens, volatile organic compounds and home use chemicals). It is the first and so far only consumer device in the market with instant testing on organic contamination..
- More important than a TDS meter --- TOC (Total Organic Carbon) and COD (Chemical Oxygen Demand) reflect the pollution of organic matter in drinking water, including natural organic like algae, pathogens, or other microbiological contaminants, as well as synthetic or volatile organic (SOC / VOC) like home/garden use chemicals or THMS. TOC reacts with chlorine and forms carcinogenic disinfection byproducts (DBP). Know and control TOC prior to chlorination of your well water.
- Instant lab grade readings --- TOC and COD readings used to require testing in a professional lab or by expensive water quality analyzer. With the innovative UV spectral technology, you can use this water quality meter and get the lab grade readings in seconds without the expensive and inconvenient water quality test.
- Companion to any water filter systems --- This water quality meter is a great companion to any water filter systems to give you the unmistaken water quality change before and after the use of a water filter system, replacement of water filter cartridges, or the effects of using a new water filter pitcher or dispenser. It can also be used to check biofouling of your RO system.
- Anywhere water quality assurance --- With its pocket size and intuitive design, you can take the water quality meter to anywhere you want to check the drinking water quality. This can be used by water professionals as the screening devices. It can also be taken to an expedition where drinking water may be from a clear river or lake. Recalibrate it with distilled water. AVOID BUBBLE ON THE PROBE HEAD IN BOTH CALIBRATION AND TESTING, BY SHAKING THE TESTER GENTLY WHILE THE HEAD IS IN SAMPLE WATER.

This water quality meter/analyzer can be used to detect and track changes of drinking water quality at raw source or the filtration effect of water filter systems on important dimensions reflecting organic compounds, oxidizable contaminants and dissolved solids in water. Using innovative spectral sensing technology, this precision device gives lab grade reading in seconds. Best Testing Coverage with TOC and COD Total Organic Carbon (TOC) is a measurement of the total amount of carbon in organic compounds. TOC in source waters comes from decaying natural organisms as well as synthetic sources like home/garden chemicals for daily use. It includes both Purgeable Organic Carbon (also called VOC, Volatile Organic Carbon) and Non-purgeable Organic Carbon. TOC has become an important parameter to monitor overall levels of organic compounds present. It covers all three organic test areas in a typical test package (microbiology, VOC and SOC). Contaminations in any of those three areas like pathogens, THMS etc. would yield a higher TOC reading. On the other hand, a normal TOC reading would generally indicate that there is no organic contamination*. High TOC in water also reacts with chlorine and forms carcinogenic disinfection byproducts (DBP). It is important to know and control the TOC level before chlorination of (ground) water.
Chemical Oxygen Demand (COD) is correlated to TOC most of the time. But it can also diverge to a high number, which means that there are higher levels of oxidation from inorganic sources like ammonia, or nitrite etc. Detection Parameter (unit: mg/L) TOC: Detection Range: 0-10, Max Error: 10%FS, Reading Resolution: 0.1
COD: Detection Range: 0-10, Max Error: 10%FS, Reading Resolution: 0.1
TDS: Detection Range: 0-2000, Max Error: 10%FS, Reading Resolution: 1
