Measures pH, temperature and (tds) EC, ppm 500, ppm 700 and CF with lab quality glass that can be used for the pool, drinking water, hydroponics, brewing, and growing EASY two point calibration and auto temperature compensation makes this digital meter a handy tool with backlit LCD display and calibration reminders

USA 1 ms/cm (EC 1.0 or CF 10) = 500 ppm. European 1 ms/cm (EC 1.0 or CF 10) = 640 ppm. Australian 1 ms/cm (EC 1.0 or CF 10) = 700 ppm. Calculating the conversion factor. If your meter allows you to switch between EC and TDS units, your conversion factor can be easily determined by dividing one by the other.

2.4EC x 700 = 1680ppm (700 scale) or 1680ppm / 700 = 2.4EC If you must grow using ppm (instead of EC), you will need to know the following; What PPM scale is the book (research material) referring to?

Ie EC X500 ECx560 or the most Common in Hydro ECx700 An electronic PPM/TDS meter actually measures EC not PPM. 1 millisiemen (mS) = 1000 microsiemen (µS) The PPM figure is a result of a conversion factor (multiplier). If the meter measures an EC of 1 mS it could convert this to the following PPM figures: 1 * 700 = 700 PPM (This is a 0.7 conversion) 1 * 640 = 640 PPM (This is a 0.64 European conversion) That means 1.0 mS/cm x 500 = 500 ppm. There are many different scales in many industries. For example, three scales are usually used in hydroponics: the 500, 640, and 700 scales. The difference between them is in their use. The 700 scale is based on measuring the potassium chloride KCl concentration in a solution: 1.0 mS/cm x 700 makes 700 ppm 0.7 (700 CF) conversion factor is for an EC reading of 1000 μS/cm = 700 ppm Automatic Temperature Compensation All readings are compensated for variations in temperature Meaning every 1000 micro Siemens= 500ppm so 0.5 convention scale Your ec meter shows micro siemens and not mili Siemens.

In other words, an EC of 1 is approximately 700 ppm. To convert from EC to ppm, simply multiply EC by the ppm scale required, e.g. 2.5EC x 500scale ppm = 1250ppm. The two scales Bluelab use are; 700ppm and 500ppm scale. There are many ppm scales around, but these two are most common. TDS is Total Dissolved Solids.
