Horiba Cardy Twin Digital EC Meter

A small quantity of calibration solution will come with this meter. We sell extra and replacement solutions for when you run out. You will need the 1,413µS conductivity standard.

Main Features:

  • cardyec_s.jpgHuge range, will measure conductivity from 1 1µs/cm all the way up to 19,999 (19.9ms/cm) using range switching.
  • Has a great feature that estimates the EC of samples that are higher than the 19.9ms/cm. A very handy feature when you are figuring out how strong a water:fertilizer mixture is.
  • Highly precise measurements from a single drop of sample meaning you can obtain readings from things like leaf sap, seeds or even saliva which would be impossible with other meters. Also makes it easier to obtain samples as less extraction of a sample is needed.
  • The sensor can be directly immersed in solutions to take measurements, enabling convenient testing of such solutions as river water (remember, only the end of the meter is waterproof).
  • Automatic calibration, with  1,413µS conductivity standard.
  • Automatic temperature compensation, and other "intelligent" functions are standard features.
  • Save money on calibration solution as only a small drop is needed to calibrate this instrument.
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:
  • cardyec2.jpgUsed 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 caused by pollution such as high synthetic fertilizers or sewage runoff.
  • 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.
  • 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.

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.

cardyec4.gif1. 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.

7. Salinity Display

8. Conductivity Display.
