Review on Highly Accurate and Reliable 3-in-1 Professional Water Test Meter: TDS, EC, and Temperature. Complete with Protective Leather Case. by Leroy Jacobs
You may need to calibrate, this is not difficult. Accurate readings
You can calibrate this meter but you must cut the bezel to the left of the "Shift" button. I used a precision knife and then twisted the handle. Not too much on arrival. This does NOT come with calibration fluid. I've seen one star reviews for this reason alone; It's a standalone counter and it does what it's supposed to do. Ideal for checking water quality and/or nutrient levels. If you want the calibration button on the outside of the meter make sure you buy the newer version 2.
