Water Testing: New Economical Heater Block for Cod Testing
Mar 28 2006
The heater block is a microprocessor controlled incubator with a dual LED display. Its multi-tube block offers significant advantages in space saving and power consumption over the traditional method. Temperature is settable from 30ÂºC to 200ÂºC with timer control. It offers rapid heat up rate within 15 minutes from ambient to 100ÂºC, and features stability, uniformity and accuracy of +/- 1ÂºC.
The Palintest TubetestÂ® system offers a simple, quick, and convenient method of testing COD which conforms to the ISO standard on sealed-tube COD testing (BS ISO 15705:2002). A sample is added to a TubetestÂ® tube, it is digested for two hours at 150ÂºC, cooled and the test colour measured using a Palintest photometer.
