This four channel degasser is very efficient at degassing mobile phase, as and when required.

The FE280 is a basic, simple, routine instrument which allows conductivity to be measured across 4 ranges with full temperature compensation. The temperature coefficient is set at 2%/oC. Ideal for standard applications such as water quality measurements or spot checks on on-line equipment.

The automatic FE287 is much more than a conductivity meter. The related mesurement of resistivity and total dissolved solids are of course possible, but in addition, salinity and concentration measurements can be performed, making the meter one of the most flexible available. Six ranges of conductivity are possible and are selected automatically. Readings are displayed in multiples of S/cm or S/m.

The BA380 is a basic, bench conductivity meter. It measures conductivity only, using automatic temperature compensation and, despite its simplicity, affords the user measurements accurate to plus or minus 1%. The meter is calibrated to one point using traditional manual controls and a conductivity standard. Once the calibration is set, the user may select the appropriate range for the sample and read conductivity value directl…
