The Milwaukee Smart TDS Monitor with Cal-Test is a unit that
continuously delivers precise readings. It reads TDS from 0-1990 ppm
with ±2 percent accuracy, triggering a visual alarm when the unit needs
to be recalibrated. This unit features one-point calibration,
accomplished with the included mini-screwdriver and a 20-mL sachet of
calibration solution, and its probe connects to a two-meter cable for
versatility in mounting. Uses 12V DC power adapter (included).
Manufacturer provides a two-year warranty for the meter, six months for
the probe.
