Westingarea supplied high quality Portable Conductivity/TDS/Salinity/Temperature Meter:


LIDA5 series are used to measure conductivity, total

dissolved solid, salinity and temperature of solution.

The series include four models:
> LIDA520 Conductivity/oC Meter
> LIDA530 Conductivity/TDS/oC Meter
> LIDA531 Conductivity/Salinity/oC Meter
> LIDA540 Conductivity/TDS/Salinity/oC Meter


LIDA5 series have built-in high performance CPU, it

can work about 200 hours continuously with one 9

volt battery.  


Single Point Push-Button Calibration:
The meter with single point calibration function, it is

permitted to use standard conductivity solution, you

need only set conductivity value of the calibration

solution at 25oC and immerse conductivity
electrode into solution, then press [ ENTER ] key, the

meter will be calibrated automatically. 


Auto Standard Solution Recognition:
In calibration, the meter will display ERROR if you use

conductivity solution by mistake.


Auto-Ranging for Conductivity:
The meter with auto-ranging function when measure

conductivity or total dissolved solid. After electrode

immersed in solution, LIDA5 series will fast response

and convert range.

Auto Temperature Compensation:
The meter 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
enter automatic temperature compensation. 


Power Monitor:

LIDA5 series have built-in power monitor chips, when

power is lower than its required, the battery indicator

will disappear automatically and suggest you replace


Adjustable Temperature Coefficient:
Solution contained different ions usually have

different temperature coefficient, LIDA5 series can be

set in the range of 0 and 3.9% per centigrade degree.


Adjustable Cell Constant:
When measure solution with higher or lower

concentration, you should choose different constant

of conductivity electrode. The meter with three cell

constants for your choose, it can save the measured
value for different constant electrode separately.

After setting the constant, you needn't calibrate it

again when replacing a new electrode.

Adjustable TDS Coefficient:
According to the theory of electrical conductivity, you

need estimate TDS coefficient when measure total

dissolved solid of solution.
LIDA530/540 can be set in the range of 0.01 to 1.00,

which can ensure accuracy of measured value.
Hold Function:
The meter with hold function, press [ MEAS/HOLD ]

key, the meter momentarily freezes reading for easy

Message Indicator:
The meter with operational message indicator. When

you need setup or measurement, the message

indicator will help you what you can do and how do it.

You can set parameter or select functions under it's



Save Data:
The meter can save 64 data sets, press [SAVE] key,

and the meter will store current measured value,

serial number, date, time and other information.


Outoput Data:
The data can be sent to computer through USB link,

you can print out test report via software.

What's included:

CON1 conductivity electrode(K=1), temperature probe,

9V battery.


CON1 conductivity electrode(K=1), CON10 conductivity

electrode(K=10), temperature probe, 9V battery.
