SC72G Inductive Conductivity Converter Yokogawa portable conductivity meter
ISC450G Yokogawa portable conductivity meter is a 4-Wire type converter designed to measure specific conductivity by using the inductive conductivity method, which is especially suitable for high conductivity measurements. It features a unique accuracy and range ability, which is only possible through superior sensor design and electronic data processing using a self tuning amplifier with more than 10 sub ranges with automatic zero adjustment at every range change.
With tht EXAxt 450 unique Human Machine Interface (HMI), it not only present reliable process data, but also diagnostics, trends, logbooks and step by step calibration routines The high resolution graphical display and the touchscreen operation make all information visible to the operator.
SC72G Yokogawa portable conductivity meter owns below typical features:
1. Unique intuitive HMI menu structure in 8 languages
2. Process data trending up to 2 weeks
3. Predefined OIML standard solutions
4. Predefined matrices for precise temperature compensation
5. Two mA-outputs and four SPDT relay contacts with display indicators
6. % weight on display showed.
7. HART® Communications
8. Approval of FM Class I, Div. 2, Group ABCD, T6 for Ta -20 to 55ºC
