Mettler Toledo Thornton Conductivity/Resistivity Instrument 200CR
**This unit is in box ready to be use. New in box unused in open box. Includes everything in pictures. See photos for further details.
The 200CRS is an analytical and process control instrument for measuring solution properties. It is user friendly, flexible and highly accurate. The 200CRS processes the signal from one sensor. A 1 line x 16 character Liquid Crystal Display (LCD) module conveys measuring data and setup information. The display is backlit for viewing in all lighting conditions. The menu structure allows the operator to modify all operational parameters by using keys on the front panel. A menu-lockout feature, with password protection, is available to prevent the unauthorized use of the meter. The 200CRS is configured with two relays for process control. The 200CRS instrument is equipped with a communication interface that can be configured as either an RS422 or an RS232. This interface provides real-time data output and complete instrument configuration capabilities for central monitoring via Personal Computer or Programmable Logic Controller.
