Keep pH in Proportion pH BOY-C1
All You Need is Throw away your beakers. With the new pH Boy, you need only one small drop of liquid to determine pH. This solid-state, ISFET (Ion Sensitive Field Effect Transistor) device eliminates the need for fragile glass electrodes. The pH probe folds neatly into a meter case sized like a pocket calculator. The portable pH Boy can be carried in a shirt pocket. It is powered by commonly available batteries which are conserved by an automatic shut-off feature. Each pH Boy includes a fabric carrying case and calibration standards in convenient plastic dropper bottles.
