Portable and more  
   The Rheometer RC1 is a rotational viscometer (Searle principle) for mobile use and l 
    
  aboratory operation.  
    
  The highly dynamic measuring drive systeme enables rotational tests where either shear  
  rate or shear stress can be pre-set (CSR and CSS).  
    
  Electronic unit, keypad, measuring drive system, and measuring spindle coupling are  
  integrated in a portable housing.  
    
    
 

Special Features

 
  
  • build-in rechargeable battery and mains power
 
  
  • parallel display of 4 optional parameters of viscosity, temperature, torque, shear rate,    shear stress, rev (on a 4 line alphanumeric display)
 
  
  • dust proof keyboard
 
  
  • torque overload protection
 
  
  • storage of the measuring conditions pre-set when Rheometer is switched off
 
  
  • data buffering in the RAM for mains and battery operation
 
  
  • serial interface for printer and personal computer
