Did u ignore me! I told u multiple ec scales so those 2 pens may be using diff ones! Until u answer that question u don’t know if its off or not! I mean I don’t use meters but pretty sure I remember that part from looking into buying meters back when i did use em!I think its just cheap ass meter and the calibration is wrong. I know what my PPM should be roughly just based on how much nutes I use, and the Yinmik meter is right where I expect.
