Sulfite is rarely found in natural waters because it oxidizes quickly to sulfate.However, sulfite is commonly used in industry, in particular, in the food sector for its preservative properties. Sulfite is also utilized in water heating systems as an oxygen scavenger. High concentrations of sulfite however lowers the pH of a solution, hence facilitating corrosion. Sulfite is also monitored in environmental analysis as it is toxic to aquatic life. Its ability to eliminate oxygen from water disrupts the ecologic equilibrium of rivers, ponds and lakes.

Magnetic 2.5L auto-reverse stirrer with tachometer, stainless steel cover, 110/115V, When stirring a solution, to work with a constant speed (Revolutions Per Minute) is an important factor in ensuring that the best repeatability in test and processes is achieved. Without a tachometer, there is no way of knowing the RPMs. HI 304N is a heavy-duty stirrer with a built-in tachometer.It is often desirable to stir in two directions in order to achieve maximum homogeneity. An advanced circuit allows HI 304N to reverse the direction of the stirring at user selected intervals. The interval can be adjusted from 30 seconds up to 3 minutes. In addition to the tachometer and precision speed control, a limiter will assure that the maximum speed is never exceeded (Speedsafe). Often, a sample is removed... Less

QC stations and labs must be able to repeat tests and processes. In order to do this, the specifications must be clear at all times. When stirring a solution, the RPMs are a very crucial factor. Without a tachometer, there is no way of knowing the exact RPMs and therefore no way of repeating the process. We solve this problem solve this problem by incorporating an LCD tachometerMagneti c 2.5L two-speed stirrer with tachometer, stainless steel cover, 110/115V .This stirrer allows for precise stirring repeatability by using two separate speed ranges. In each range, the speed can be fine tuned for exacting accuracy. This assures maximum repeatability in experiments and processing for laboratory as well as production use.
