AUTOMATIC TITRATIONS T h e Coleman Titrion, t o g e t h e r w i t h the C o m p a n i o n p H Meter, provides an instrumentation p a c k a g e capable of automatically performing virtu ally a n y electrometric titration in t h e analytical laboratory. Speed—complete automatic titration in 1 to 1V2 m i n u t e s . Accuracy, Sensitivity—routine accu racy well within 0.1 p H ; 2 millivolt potential difference operates titrant flow control. Automation—electronic sensing of end-point a p p r o a c h ; electronic con trol of titrant flow;panel lights for operating a n d end-point signals. Economy—high-volume o u t p u t cuts unit cost of titrations; C o m p a n i o n m o u n t s on Titrion control case t o conserve b e n c h space. Versati I ity—instrumentation a d a p t s to a n y titration curve; provision for continuous titration; operates over 0-14 p H a n d 1400 millivolt r a n g e ; t e m p e r a t u r e compensation.
