Cardy Twin EC
*Product Manual Below*
Remember to purchase the Conductivity Standard to calibrate. We recommend 1,413µS for this instrument, link at the bottom.
Main Features:
Highly precise measurements from a single-drop sample.
- The sensor can be directly
immersed in solutions to take measurements, enabling convenient
testing of such solutions as river water.
- Automatic range switching gives a
wide measurement range of 1µs/cm~19.9ms.
- Automatic calibration, with 1,413µS conductivity standard.
- Automatic
temperature compensation, and other "intelligent" functions
are standard features.
Incorporating a flat sensor, the Cardy Twin EC conductivity meter can measure
the conductivity of a solution from a single drop of sample. Users can
either place a sample on the meters flat sensor on immerse the meter
directly in the solution being tested, giving the meter a broad range
of applications e.g. measuring rainwater pollution levels or the
electric conductivity (EC) of solutions used in agricultural
operations. Also, The B-173 meter includes a convenient salinity
conversion indicator.
Recommended Uses:
- Used in our leaf sap analysis to determine nutrients not yet complexed into sugars.
- To measure the concentration of nutrients in foliar and hydroponic fertilizers.
- To measure the level of water soluble nutrients available to crops in the soil
- To monitor the salinity of soil so you can manage the damaging effects of high salts.
- Used to determine what Dr Carey Reams called "ERGS" (energy released per gram per second) 1 ERG is equal to 1 microsiemen. He recommended soils have around 200 ERGS and no more than 1000 ERGS.
- Ideal for use in the Reams Urea test.
-
The measurement of conductivity is indispensable to controlling the water quality of rivers, lakes, underground water, waste water, etc.
-
The perfect way to check sea water desalination systems used on small ships and cruisers.
- Also important for monitoring fish tanks and other aquatic systems.
Nutrients in the soil are only available to the plants in ionic form when dissolved in the soil solution. This EC meter which measures the quantity and mobility of ions (cations & anions) and is perfect for seeing an overview of the amount of nutrients available to the crop. You can also monitor if conductivity is too high which indicates high salts and your plants may be vulnerable to burn.
Cardy Twin EC Meter Anatomy

1. The sensor: The cartridge-type sensor can be easily replaced
if nenessary.
2. HOLD button: When pressed during measurement, the current
value will be held. If the Power On button is pressed simultaneously,
the value will be held automatically after stabilization.
3. CAL/MODE button:Press the Cal/Mode Button to switch between
calibration mode, salinity mode, and conductivity mode.
4. Power button: Turns power on and off. If the power is not
turned off within 15 minutes after last use, it will automatically
turn itself off.
1. Conductivity/Salinity
Display: When the conductivity value is above 20 mS/cm
or the salinity is above 1.1%, the display will flash.
2. Battery Alarm: Alters you when the battery is low.
3. Hold Mark: Appears to indicate the measurement value is
being held. During Autohold mode, the mark will flash.
4. Temperature Alarm: The "°C" indicator will light when the
sample is below 5°C or above 35°C.
5. Calibration Mark: Appears during calibration.
6. Stability Mark: Appears when the measurement value has stabilized.
