ISC450G Inductive Conductivity Converter
Brand: Yokogawa Electric CorporationThe new EXAxt 450 series has been designed to meet the highest market requirements of today’s industry.
This series of analyzers is unique as it will no longer be the uncertainty factor of your quality demands, but instead will bring you to a higher level.
The EXAxt will help you and guide you as the unique Human Machine Interface (HMI) will not only present you reliable process data, but diagnostics, trends, logbooks and step by step calibration routines to become your friend in analytical measurement and help you gaining that higher level of quality.
The instrument is easy to set up, very intuitive and can be used without the need of an Instruction Manual.
The HMI has a clear menu structure in the language of your preference (English, French, German, Spanish, Italian, Swedish Portuguese and Japanese.)
The touch screen interface provides access to the display features.
The main display gives three process values at the same time.
Features- Unique intuitive HMI menu structure in 8 languages.
- Process data trending up to 2 weeks.
- Predefined OIML standard solutions.
- Predefined matrices for precise temperature compensation.
- Two mA-outputs and four SPDT relay contacts with display indicators.
- %weight on display.
- HART® Communications.
- FM Class I, Div. 2, Group ABCD, T6 for Ta -20 to 55ºC
