POCKET PAL  
        METERS®  
        Handheld, lab  
        accurate and modestly priced, the Pocket Pal meters are an industrial  
        standard. Pocket Pal series electrodes are field replaceable and usually  
        can be changed and calibrated in a matter of minutes. Digital displays,  
        rugged ABS plastic housings and precision two-point calibration  
        potentiometers make all seven Pocket Pals perfect for field, plant or  
        laboratory use.  
        With Automatic Temperature Compensation standard (except PH-2), accurate  
        response is just seconds away. Each Pocket Pal comes equipped with a  
        9-volt battery, calibration screwdriver, instruction card and a handy  
        belt loop case. 
        DUAL pH  
        & CONDUCTIVITY - THE MOST POPULAR POCKET PAL METER  
        DSPH-1 and DSPH-3  
        POCKET PAL meters measure pH and conductivity in a compact one-hand  
        operation. There are no electrode cables to fool with. The electrodes  
        simply fold under the instrument for storage. Two test buttons control  
        all operations. Temperature variations are automatically compensated for  
        both pH and conductivity measurements. Easy screwdriver adjustments  
        include Cal and Slope for pH, and Zero and Span for conductivity. The  
        POCKET PAL operates on a 9-volt battery (included). 
         DSPH-1/DSPH-3  
        METER  
        For versatility in  
        the field or the laboratory, the DSPH-1US/1PPM and DSPH-3US/3PPM feature  
        pH, conductivity and total dissolved solids measurements in one handheld  
        instrument. The DSPH-1US/1PPM measures pH from 0-14 and conductivity  
        from 0 to 19,999 in µmhos or ppm, and the DSPH-3US/3PPM extends  
        the conductivity measuring range to 199,999 in µmhos or ppm.  
        Recessed switches control all functions and an easy access panel  
        contains adjustments for pH calibration and slope, zero and span for  
        conductivity. Features include automatic temperature compensation (ATC),  
        detachable electrodes and integral benchtop stand.

         pH METER - PH-2  
        The pH-2 is the ideal pH meter for general purpose pH measurements in  
        plant, field production line or laboratory environments. Simply dip the  
        probe into the sample fluid and the pH valve will be digitally  
        displayed. Unit features manually adjustable temperature compensation  
        and replaceable pH probe.

        The ORPH-7 is a dual function meter for measurement of both pH and  
        Oxidation Reduction Potential (ORP). In such applications as swimming  
        pool maintenance and chrome reduction where the ORP is pH dependent the  
        ORPH-7 user can easily switch between displays without removing the  
        probes from the sample and introducing sampling errors. Automatic  
        temperature compensation improves the precision of the sample analysis.

        DISSOLVED OXYGEN/TEMPERATURE METER - D0-6  
        The DO-6 combines a polargraphic dissolved oxygen sensor with an  
        integral RTD for dissolved oxygen and temperature measurement in the  
        laboratory, plant or field. The unit contains a small cathode which  
        consumes minimal oxygen, thus reducing the need for sample stirring and  
        providing a more stable response. Standby switch stabilizes the probe  
        prior to use while economizing the battery power normally required for  
        the display.
