M pH, Conductivity/TDS & DO Meters POCKET PAL METERS® Handheld, lab accurate and modestly priced, the Pocket Pal meters are an industrial standard. Pocket Pal series elec- trodes 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 opera- tions. Temperature variations are automatically compensated for both pH and conductivity measurements. Easy screwdriv- er adjustments include Cal and Slope for pH, and Zero and Span for conductivity. The POCKET PAL operates on a 9-volt Water Quality / Analytical Water battery (included).
