The Benchtop 4-Vial COD Reactor is used for the digestion of COD (Chemical Oxygen Demand) samples.
The principle behind COD detection is that almost all organic molecules can completely oxidize to carbon dioxide when exposed to an acidic environment and a powerful oxidizing agent. COD is commonly expressed as the mass of oxygen consumed over the volume of the solution.
The Benchtop Spectrophotometer LH-T725 adopts high-brightness LED cold light source and advanced parallel optical structure. It is developed according to national environmental standards. It is equipped with an intelligent detection system, collecting data dozens of times per second, filtering algorithm to filter out interference and improve data accuracy. The 7-inch IPS large touch screen makes the test results intuitive and clear and is a good assistant for scientific research, data analysis, and water quality testing.
The amount of dissolved oxygen in a water sample is measured using fluorescence technology in this portable, easy-to-use probe. Measuring at a range of 0-20.00mg/L or 0-200% saturation level, this probe is manufactured in strict accordance with the international standard of the ISO 9001: 2015 quality management system.
Green LED light irradiates a red fluorophore within the probe. The quenching properties of oxygen in the water sample reduce the lifetime of the red fluorophore, producing an inversely proportional relationship between dissolved oxygen content and red fluorescence, this can be measured to mg/L or percentage saturation level.
Used to measure biochemical oxygen demand to determine the amount of dissolved oxygen within a sample, the Intelligent BOD meter got its name from its ease of use. Using a Mercury-free testing method, this tool has an automatic reading capacity with data uploaded wirelessly for data input and printing (upgrade model only). The Intelligent BOD meter is a great apparatus for those within the water quality testing industry. The standard set with apparatus and testing reagents has the ability to conduct 60 data points while the upgrade set has the capacity to test up to 960 data points.
Perfect for researchers on the go, this lightweight, small, portable pH analyzer has a range of between 0.00-14.00 with a resolution of 0.01 and accuracy of less than or equal to a pH of 0.02. With a lithium battery, this apparatus is rechargeable. Graded with an IP65, this sensor is dustproof and water-resistant.Â
