TB400G Turbidity Meter

Brand: Yokogawa Electric Corporation

Turbidity analyzers conventionally used for the operation and control of a water purification plant, are nowadays being required to measure the amount of matter suspended in various sorts of industrial waste water and to detect the turbidity of chemical processes.

Since their sales began in 1959, Yokogawa's process-use turbidity analyzers, centering on the area of water supply, have achieved a number of records and have provided high reliability to many users.

The TB400G surface scattering light turbidity analyzer has a microprocessor to provide intelligent features for advanced performance and high reliability.
Features
  • 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.
