For my meter, I needed the standards for the 4.01 pH and the 7.01 pH. I also needed to calibrate the EC and needed a solution with a known EC value (μS/cm) (Photo 2).

ET-01 JEDTO EC/TDS/ temperature Meter เครื่องวัดค่าความนำไฟฟ้า มวลสาร และ ppt . EC150 Extech EC where TDS is expressed in mg/L and EC is the electrical conductivity in microsiemens per centimeter at 25 °C. The correlation factor k e varies between 0.55 and 0.8. Some TDS meters will use this electrical conductivity measurement to then infer the number of parts per million (ppm); 1 ppm indicates 1 mg of dissolved solids per kg of water.

Digital EC/TDS/Temp Meter Adwa, AD 32.

To ensure that the EC and pH levels are correct, the combination PC5 EC/pH/Temperature meter does both. Een ec meter (Electric Conductivity) of microsiemens meter genoemd, kun je gebruiken om het zoutgehalte (salinity) van een vloeistof te meten. Het zoutgehalte kun je ook lezen als het aantal voeding dat aanwezig is in het water Once you have “re-wet” the probe, you will now need to calibrate the meter again.

Add to Alibaba.com offers 1,016 ec ppm meter products. A wide variety of ec ppm meter options are available to you, such as certification, customized support, and after-sales service provided. An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution.It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.

If I was being purely logical I would say go with the EC system. The meters cost more, but the numbers will be universal and not as open to silly mistakes. However, I cut my teeth with the PPM system and kept my meter faithfully set to 0.5. Which means that when I think of mixing nutrients I think in PPM, but that’s just me. 31 ส.ค. 2020 - EC คือ ค่าความนำไฟฟ้า (Electrical Conductivity) เป็นค่าที่บอกระดับความสามารถในการนำกระแสไฟฟ้าของของเหลวนั้นๆ ซึ่ง ค่า Conductivity ต่ำๆ แสดงว่าน้ำบริสุทธิ์ LAQUA Twin EC Meter $196.00 Replacement to part 2205L, the upgraded LAQUA pH meter offers better resolution, increased measurement range, and three point calibration functionality.
