LIGHTWEIGHT WATER PURIFIER
ULTRAMETER
GENERAL
This work package contains information and operating instructions for the Ultrameter Model 6P portable, water
quality monitor instrument. The instrument is used in the field as a hand-held, microprocessor-based, battery
operated unit to determine the quality of raw water source and product water.
SPECIFICATIONS
The instrument measures alkalinity (pH), Oxidation-Reduction Potential (ORP), conductivity, Total Dissolved
Solids (TDS), resistivity, and temperature to the specifications in Table 1. Only measurements of pH,
conductivity or TDS will be required to operate the LWP. It also allows for storage of readings in the memory but
this is not necessary for operation of the LWP.

ULTRAMETER OPERATION NOTES
The TDS is measured in NaCl standard but is calibrated using the 442 standard solution. See WP 0049 00.
Always rinse and the conductivity cell or pH/ORP sensor well with test solution three times and refill. Press the
desired measurement key to start measurements. Pressing the key again does no harm the unit but it will reset
the 15-second timer. After 15 seconds of inactivity the instrument automatically turns off; 60 seconds in CAL
mode. The instrument is waterproof and floats.
