What is COD (Chemical Oxygen Demand)?

COD (Chemical Oxygen Demand) measures the amount of oxygen that would be needed to chemically oxidize organic and inorganic substances in water. In simple terms, it tells you how much pollution (organic matter, chemicals, or waste) is present in the water.

The higher the COD value, the more contaminants there are — indicating poorer water quality.

Why is COD important to test?

• Pollution Detection: High COD levels often mean the water is polluted with organic waste (such as from sewage, industrial discharge, or decaying plants).

• Health & Safety: Contaminated water with high COD may carry bacteria, viruses, or toxic substances that can be harmful if consumed or used.

• Environmental Protection: For industries and environmental monitoring, testing COD helps ensure wastewater isn’t harming rivers, lakes, or groundwater.

• Aquaculture & Gardening: Fish, plants, and crops are sensitive to water quality. High COD can damage ecosystems or reduce crop yields.

• Quick Indicator: COD gives a fast snapshot of overall water cleanliness.

Why use a Water Quality Testing Pen for COD?

• Portable & Fast: Instant readings on-site, no need for lab analysis.

• Multiple Parameters: Get COD along with TDS, TOC, EC, temperature, and UV — a full water quality profile in one device.

• Easy to Use: No complicated setup — just dip, press, and read.

What is TOC (Total Organic Carbon)?

TOC (Total Organic Carbon) measures the total amount of carbon found in organic compounds in water. Organic carbon comes from sources like:

• Decaying plant and animal matter

• Industrial waste

• Sewage or wastewater

• Agricultural runoff (fertilizers, pesticides)

A higher TOC value means there is more organic contamination in the water.

Why is TOC important to test?

• Water Purity Indicator: High TOC can signal the presence of pollutants that may affect taste, odor, or safety of drinking water.

• Health Concerns: Organic contaminants can react with disinfectants (like chlorine) to form harmful byproducts (e.g. trihalomethanes).

• Regulatory Compliance: Many industries (like pharmaceuticals, food production, and water treatment plants) monitor TOC to ensure water meets strict safety standards.

• Environmental Monitoring: High TOC can harm aquatic life by reducing oxygen levels as organic material decomposes.

• System Performance: In water treatment systems (like RO filters), monitoring TOC helps verify how effectively the system is removing organic contaminants.

What is TDS (Total Dissolved Solids)?

TDS (Total Dissolved Solids) measures the combined content of all inorganic and organic substances dissolved in water. These solids can include:

• Minerals (calcium, magnesium, potassium, sodium)

• Salts

• Metals

• Organic matter

TDS is expressed in parts per million (ppm) or milligrams per liter (mg/L).

Why is TDS important to test?

• Water Taste & Quality: High TDS can affect the taste, appearance, and overall palatability of drinking water.

• Health Monitoring: While some dissolved solids are harmless or even beneficial, very high levels may indicate harmful contamination from industrial waste, sewage, or agricultural runoff.

• Appliance Protection: High TDS can cause scale buildup in water heaters, coffee machines, and RO filtration systems, reducing efficiency and lifespan.

• Aquariums & Hydroponics: Sensitive aquatic life and plants require controlled TDS levels for optimal health.

• Swimming Pools & Spas: TDS monitoring helps maintain water balance and clarity.
