Microprocessor-Based,2-point Push Button Calibration,Auto-Buffer Recognition,Self-Diagnostic with Message Codes
PHM-W SERIES BENCHTOP pH/mV METER
PHM-W Series benchtop pH/mV meters includes models
PHM-25CW, 3CW and 3BW for the measurement of acidity
and alkalinity in liquids.
AUTOMATIC CALIBRATION:
The meters is capable of calibrating up to 3 points using
USA or NIST pH standard buffer. Press CAL key to enter calibration mode and immerse pH electrode into indicated calibration solution, press ENTER key and meter is
automatically calibrated.
AUTO-BUFFER RECOGNITION:
During calibration, if the calibration solution does not
match the meter’s indicated value, an ERROR message
is displayed.
VIEW ELECTRODE SLOPE:
After calibration, the percentage slope of the electrode is
displayed before the meter returns to measurement mode.
Per the slope value, you decides whether to change the pH electrode.
AUTOMATIC TEMPERATURE COMPENSATION:
(FOR PHM-3BW)
Using the supplied temperature probe, the temperature value
is displayed on the screen. The meters provides manual or
automatic temperature compensation mode for optimum
accuracy under variable temperature conditions.
FLUID RESISTANT HOUSING
AND SWIVEL ELECTRODE HOLDER:
The integrated plastic housing and keypad is sealed to
protect against accidental spills and splashes. The electrode
holder arm is rapidly switched to both sides and swivels and
articulates for convenient use and positioning.
METERS INCLUDED:
pH Electrode, pH Standard Buffer, Electrode Holder, Power
Adapters, Temperature Probe (Only for PHM-3BW)
