WA 7700 is an integrating sphere type turbidimeter/color meter. A cell of 5mm to 100mm is usable, so you can measure a sample from low to high turbidity range. Thanks to its double-beam measuring method and automatic calibration function, high accuracy and stability are maintained even for long hours of measurement work. This model will be a most suitable instrument to control water quality for a wide range from raw water to clean water.

Features

Measurement is possible for the turbidity of 0 to 100 NTU (by polystyrene) and 0 to 1,000 NTU (by kaolin), and chromaticity of 0 to 1,000 TCU.

Highly reliable measurement is available as pre-shipment calibration has been done using turbidity and color standard solutions.

This model has such calculation functions as CV value, standard deviation, correlation coefficient, etc. Multiple working curve data can be also input.

It is an all-in-one type instrument that consists of operation panel, fluorescent character display and built-in printer.

It is possible to connect an auto sampler (option) to this model, by which multiple samples can be automatically measured and labor is saved.

Using data transfer software (option), you can transfer measurement data to your personal computer.

AT-15/AT-48 are auto samplers to be used in combination with WA 7700 for automatic and laborsaving multiple measurements. 15 tall beakers (AT-15) or 48 tall beakers (AT-48) can be set on its turn-table. With one-button operation, calibration, water feeding, measurement, drain and cleaning are automatically repeated. These models have an optional expandability of adding pH measuring function and EC measuring function (option).

Features

A job sequence is fully automated for calibration, water feeding, washing by sample water, measurement, drain and cleaning.

Approx.100second high speed measurement is possible for one sample’s color and turbidity measurement (approx.4minutes for pH specification, approx.5minutes for EC specification).

Using data transfer software (option), you can transfer measurement data to your personal computer.
