How to use a TDS/EC meter, and how to convert
Тәжірибелік нұсқаулар және стиль
In this video I show how to use a TDS/EC meter. I also explain the different scales used around the world, 500, 640 and 700 being the most common. By using the EC (electrical conductivity) setting you can multiply the millisiemens by the particular scale you use. There are 1,000 microsiemens in a millisiemen. For instance if your EC reading is 1440 microsiemens (1.44 millisiemens) and you wish to convert to European 700, it is 1.44 x 700 = 1008 ppm. Using the US 500 scale it is 1.44 x 500 = 720 ppm.

Hello everyone. Great information. Can anyone please you tell me which battery to use in this TDS/EC meter?

The calibration is done in ML so they give a slight preference to the European system ;) Merci Pascal

Ah well that makes a change. Would think using just ec would be a better solution. Thank you for watching

@@growNglow Yeah it's real confusing, TDS is the same as PPM? Or is it EC?
@growNglow

EC is the electrical conductivity of the liquid, and that is where the numbers derive from

@@growNglow I read that EC is the base value from which the others (TDS and PPM) are measured (or calculated?). Can you confirm that? Would it hence be best to focus mainly on EC? Thanks Pascal and good weekend.

@@nikolasmaes99 Yes. The meter sends a current from one probe to the other, and electrical measures conductivity (EC)

Are there any inexpensive ones that have temp compensation? Without temp compensation they are pretty bad going all over the place in readings.

I doubt it. If 100% accuracy is required you can make the compensation adjustment manually. Most are calibrated at 25C

For hydroponics, 25C is near perfect in many applications. We use cooling to get it down to 24C or 25C, as the water is naturally over 30C because of the heat

@@growNglow I am so lost. Meters came and I popped out my tomato to test its water and rock steady at 30c and 0186 us/cm I am stumped what all that means or where it should be. edit: From what I was able to gleam from the net I should be around 2-5 millisiemens which is 2000-5000 microsiemens. I added a lot more nutrients and each one is now around 2000-2100 on my meter.
Why my TDS tester show 9999 when I test my hydroponic nutrients in water. I just newly brought the tester. Is it I premix the nutrients and left there for too long

I doubt it. Try it in something else to see if it is faulty. Did you check the battery?
To know this water good or know which number should be ?

I do not understand. You can write in a different language, and I can translate
So let's says my ppm is 500 is it 500 x 2 ÷1000 is 1 EC and 1 EC 1x1000 ÷ 2 500 ppm I have the same vivosun is it going off of USA measurements

I am not sure what you mean. This item is from US and the TDS scale is 'scale 500'. You do not need to calculate anything. You can change from EC to TDS with the button.

Use a screwdriver or blunt blade to prize out the end. There are two little batteries there
So what's the ec

Electrical conductivity. That is how all testers work. The other scales are take from EC.
How's she goin'? I wish I knew more about what you are talking about Pascal!! But I'm sorry, I'm lost on this none!!! Take care!!!

Hi Mike. Haha. It is really measuring the amount of fertilizer in your hydroponics solution. I will do a video on hot peppers next, and I might be able to convert you over to spicy food. Take care and Hi to Nannie

Just use EC if you find the conversions too difficult
