Ushers in new standards of performance The new Mitsubishi VA-02 Moisture Vaporizer offers shorter measuring time, greater range (starting at 5 ppm) and better reproducibility than conventional direct drying or indirect solvent extraction methods. Trace amounts of water in chips, powders, even solids, can be accurately measured by the VA-02. And it's totally unaffected by atmospheric humidity. The CA-02 Moisture Meter employs the coulometry principle applied to Karl Fischer titration to eliminate the troublesome procedures involved in conventional titration. It's fully automatic and easy to use. For complete information on both models, contact your nearby Cosa dealer. Or contact Cosa Corporation, 17 Philips Parkway, Montvale, N.J. 07645.
