No need to be without an expanded scale pH m e t e r - i t ' s only $ 4 0 more.
' h o t o v o l t ' s Expander IV, p H m e t e r 112, is '395.00 — only $40 more than most laboratory aodels. tny r a n g e of four pH units can be expanded ver the entire scale. This solid state unit is eadable and reproducible to within 0.005 pH nd accurate to within 0.01 pH. An expanded nillivolt range, ± 140 mv, readable to 0.5 mv xtends Expander IV's ability to all ion selecive electrodes.

Expander IV is supplied with a single, fast, high-sensitivity electrode, but it also accepts all others, including ion selective and redox elec trodes. An output is available for Karl Fischer t i t r a tions, as well as a 10 mv recorder output. Our point of view is t h a t there is no longer any r e a s o n to be w i t h o u t an expanded scale p H meter. W h a t ' s your point of view?
