LABMAN LMMP-30 water quality meter is designed for high performance and easy
operation. The meter is capable of measuring up to 7 water quality parameters,
including pH, ORP Conductivity, TDS, Salinity, Resistivity, and temperature.

MULTI-POINT PUSH-BUTTON CALIBRATION
The meter has multi-point calibration mode. From setup menu, choose calibration
and immerse electrode into indicated calibration solution, press ENTER key and
meter is automatically calibrated.
AUTO-BUFFER RECOGNITION
During calibration, if the calibration solution or selected value does not match the
meter's indicated value, an ERROR message is displayed.
VIEWING OF ELECTRODE SLOPE
After calibration, the percentage slope of the electrode is displayed before the
meter returns to measurement mode. Per the slope value, user decides whether to
change the electrode.
AUTOMATIC TEMPERATURE COMPENSATION : By using temperature probe
AUTO-RANGING FOR CONDUCTIVITY
The meter has auto-range functions for measuring conductivity and total
dissolved solids (TDS). Upon immersing conductivity sensor into sample
solution, the screen immediately displays the value in appropriate
measurement range for accuracy,

ADJUSTABLE TEMPERATURE COEFFICIENT
Various ions in solution have different temperature coefficients.
LABMAN-LMMP30. can set the temperature coefficient between 0 and
3.9% in degrees centigrade for optimum accuracy.
ADJUSTABLE CELL CONSTANT
The meter has three cell constants for measuring requirements. Once a
cell constant has its calibration set, it is saved and does not require
re-calibration when switching meter.
MESSAGE INDICATOR
LABMAN-LMMP30 displays helpful messages like an on-screen manual for
easy operation of this meter and selection of the various options.
SAVE AND COMMUNICATION INTERFACE
The meter all has real-time date/clock stamps. The memory stores up to
99 discrete data sets. Press the SAVE key to store the current measured
values and it automatically generates a serial number with the date
and time. This data can then be sent to a computer via the USB port
