Hello, I just bought TDS Dist 1, for the calibration, do I need to adjust the buffer to 25°C first? Or just directly plunge the electrode to the buffer fluid? Thanks

I'm confused on calibration. Do I use a specific solution or the water I plan to use in my hydroponic system before adding nutrients? Please help. I have a dist 4

[cdh]

when i buy them, do they come with some calibration fluid, or are they pre-calibrated, or do i need to buy that extra right away?
