Surface Scattering Light Turbidity Analyzer TB400G

*	Equipped with a microprocessor, allowing provision of advanced performance and high reliability.
*	Enhanced self-testing functions such as detection of a disconnected lamp, a converter check, and upper and lower limit alarms.
*	Provided with multiple functions such as automatic zero calibration.
*	Compact and lightweight. The system allows access from the front, offering easy maintenance.
*	Use of the surface scattering-light measuring method eliminates the measurement errors caused by contamination of the cell port.
*	Signal smoothing as a measure against air bubbles in water samples.
