UNSURPASSED... for critical clinical and research pH determinations!
Here, for the first time, is a digital pH meter with a completely electronic display system for the pre cise measurement of pH and specific ion electrode potentials. In fact, the " 8 0 1 " is so truly digital, it can be interfaced with digital printers, computer typewriters, or time-shared computers, if you wish. The numbers on this sophisticated instrument are an inch high — clearly visible even at a distance thirty feet away . . . in pitch darkness or in broad daylight. Continuous millivolt readings are taken without polarity switching, range selection or scale inter polation. Polarity indication is automatic. You can vary the display time to suit your con venience . . . from 0.6 to 6.0 seconds, or until you have an opportunity to record the reading. There are no moving parts in the entire display system. Because of the outstanding repeatability obtained with Model 801, it cannot be surpassed for critical clinical and research pH determinations . . . or for accurate specific ion activity measurements, espe cially when Orion's new series of electrodes are used. Why not ask us for details on this revolution ary new pH meter?

OPERATES O N TWO 80< RADIO BATTERIES FOR 6 - 1 2 MONTHS measures total water hardness · fluoridation levels · calcium, eupric, chloride, bromide, perchlorate and iodide ions · pH and redox potentials This all solid-state meter is designed especially for use with Orion's grow ing series of specific ion electrodes. It can be used either in the " l a b " or in the field — both winter and summer. Boasts many features found only in the best expanded pH meters. Repeatability is ± 0 . 0 1 5 pH and ± 0 . 1 5 mv on expanded scale. Comes in a handy carrying case with two bat teries, support rod, electrode holder, bottles and plastic beakers.
