This combined pH & EC Meter gives accurate readings of nutrient solution and is very helpful in mixing right nutrient concentrate for plants with hydroponics and with soil growing.

 

With this meter you can measure for:

  • EC meter gives EC/TDC value = the amount of nutrient content in water

  • pH meter gives pH value of the water

  • water temperature

 

How to use EC and pH meter

 

All meter readings are automatically temperature compensated. It is easy-to-use as you can just dip the sensor into the test solution - stir and wait. This unit will deliver a stable reading in about 10 - 20 seconds.

 

The EC value of plant nutrient water for e.g. herbs should be 1.2, which in the meter is 120 (= EC 1.2), but the nutrient value can vary between 080-250 for different plants. To adjust the EC value in water; add clean water to lower EC value or to increase EC value add nutrient solution to the water tank. To lower the too high EC value of full water tank, the water must be replaced at least partly with new neutral water.

 

The pH of plant nutrient water should be about 5.8 (between 5.4 and 6.2). To correct the water pH value  add some pH + or - adjusters that can be found from the store.

 

CALIBRATION OF THE pH & EC METER
 

EC and pH measurements should be calibrated every few months. There is included screw driver for this with the meter.

 

Calibrate the meter using pH buffer agents and EC calibrators found in the store.

 

Calibration of the meter to pH 7

  • Open the screw cap on the meter, which shows the batteries

  • Use the EC / pH button to select the pH to be measured, the display will show a low PH

  • Remove the probe cap, immerse the probe in the pH 7 solution

  • Wait for the meter to stabilize, then adjust the meter to 7.00 by turning the small PH screw next to the batteries.

  • Rinse the meter head with water and replace the protective cap

 
Calibration of the meter to pH 4

  • By also calibrating the meter to pH 4, you ensure that the meter is calibrated over the entire measuring range

  • Remove the probe cap, immerse the probe in the pH 4 solution

  • Wait for the meter to stabilize, then adjust the meter to 4.00 by turning the small PH screw next to the batteries.

  • Rinse the meter head with water and replace the protective cap

 

 

EC calibration of the meter

  • Open the screw cap on the meter, which shows the batteries

  • Select EC to measure with the EC / pH button, the display will read X10 US with a small

  • Remove the probe cap, immerse the probe in the EC / CF calibration solution

  • Wait for the meter reading to stabilize, then adjust the meter to 280 by turning the small TDC / EC screw next to the batteries.

  • Rinse the meter head with water and replace the protective cap
