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.

Range: 0 to 14 pH / Resolution: 0.01 pH
Temperature Compensation: manual 0 to 100°C

FOUR-RANGE, PORTABLE, DIGITAL CONDUCTIVITY METER - TDS-4
The TDS-4 is a handheld four-range conductivity meter that may be used to test samples ranging from pure water to seawater. For accuracy of measurement, automatic temperature compensation is provided from 0 to 70°C using a 1000ž RTD.

DUAL pH/ORP METER - ORPH-7
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.

SPECIFICATIONS
Range: 0 to 14 pH, ±1000 mV ORP
Accuracy: ±0.02 pH; ±15 mV ORP
Resolution: 0.01 pH; 1 mV
Automatic Temperature Compensation: Automatic 0 to 70°C

PORTABLE DIGITAL 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.
