Photometer test system measures wastewater pollutants

The Tubetests photometer system is programmed to measure ammonia, COD (chemical oxygen demand), nitrate, total nitrogen, phosphate and total phosphorus. Typical applica-tions include the monitoring of factory effluents, agricultural run-off and landfill leachate. The system enables wastewaters to be tested prior to discharge without the need to make up and dispense liquid reagents or use laboratory equipment. All the test chemicals are supplied pre-measured and pre-mixed in disposable glass test tubes. When a water sample is added to a Tubetest it produces a colour change and the parameter under test is measured by the photometer which gives a direct reading on a LCD. The results of up to 300 tests can be stored in the photometer’s memory together with time, date and sample number data. Tubetests are available for COD measurement in four ranges to match effluent organic load from 0 to 150 mg/l up to 0 to 20 000 mg/l. Ammonia can be measured either by the traditional Nessler method or the modern Indophenol test. All of the tests are based on standard laboratory methods for wastewater and environmental compliance monitoring.
