pH Meter (LIDA540)
pH Meter (LIDA540)
PORTABLE CONDUCTIVITY/TDS/SALINITY/oC METER
LIDA540 is measure conductivity, Total Dissolved Solid,
Salinity and Temperature. The series have four models:
LIDA540 Conductivity/TDS/Salinity/oC Meter
Microprocessor-Based:
The meter is designed in CPU. Even can work about 200
hours continuously with one 9 volt battery.
Single Point Push-Button Calibration:
The meter can calibration automatically after it matched with standard solution. In calibration, The meter with function of
auto recognition. If you used standard solution by mistake, it
will display tips automatically.
Auto-Ranging for Conductivity:
The meter with function of auto ranging when it measuring
conductivity or TDS. After electrode immersed in solution.
LIDA5 series will scan the current value and convert range.
Automatic Temperature Compensation:
The meter with function of automatic calibration and
measurement, it will recognize the temperature sensor
automatically and measure temperature after temperature
sensor connected to the host. If the conductivity electrode
connected to it. The meter will measure automatically.
Power Monitor:
LIDA540 built-in power monitor and control chips, when
battery's power is lower than its required, the battery icon
on LCD will disappear automatically and suggest you replace
batteries.
Adjustable Temperature Coefficient:
Solution contained different ions usually have different
temperature coefficient, and it's importment to set the
coefficient correctly for precise measurement. LIDA540
can be set in the range of 0 and 3.9%/oC.
Adjustable Electrode Constant:
When measure solution with higher or lower concentration,
You should choose different constant of conductivity
electrode, The meter with three cell constants (K=0.1/1/10)
for your choose, so you can set it match with the electrode
you choose. The meter can save the measured value for
different constant electrode separately. After setting the
constant, the meter will work properly, you need' t calibrate
it again when replacing a new electrode.
Adjustable TDS Factor:
According to the analyse theory of conductivity, It need
user estimate TDS factor it be set, LIDA540 can be
set in the range of 0.01 to 1.00, which can ensure
accuracy of measured value.
Operational Message:
LIDA540 with function of operational message. When
you need a certain setup or measurement, the message
will help you what you can do and how do it. It equals to
the instruction of user's manual, You can set and measure
conveniently under it's guide.
Save Data:
The meter can save data 64 sets. Press [SAVE], and the
meter will store current measured value automatically and
serial number, date, time and other information.
Output Data:
The data stored in meter can be sent to PC through link.
You can also save measured value or print out test report
via software.
