Review on 📊 Apera Instruments Conductivity Multi Parameter Replaceable: Superior Performance for Precise Measurements by Derek Dolla

Last year I asked my wife if I could plant a herb garden on the patio. We love cooking and fresh herbs and they are never on hand when you need them. She agreed. As with any other hobby I pursue, I'm going BIG. This small container garden with herbs has been transformed into different gardens. I built 3 different 4x8 raised beds, added more containers of fruit and veg throughout the garden, and built various hydroponic systems. I have 2 strawberry hydroponic vertical walls hanging from my patio railing. Dutch bean tower and tomato systems. DWC herbs and hot peppers. I'm working on a smoke machine based hydraulic system. When following the online instructions for mixing nutrients, I encountered some issues with the hydraulic systems. I had a cheap pH meter and a PPM meter. I decided to buy a more professional meter to make sure my pH and nutrient readings were accurate. They weren't. When I received the Apera PC60 I found that my pH meter was off by 0.5! In hydroponics, this is a huge gap. My PPM meter was off a bit too, but not by that much. This tool really helps me control my hydroponics. Apera PC60 is very easy to use. It comes with everything you need to calibrate so you can be confident in your readings. I even tested it with the 1000 TDS calibration solution I had and it reads great! The display is easy to use and the backlight is very convenient. I love that the "lid" is made to be filled with liquid, has a fill line, and closes securely around the handle. Then he can calculate different filling levels in the liquid. I no longer have to bend down and stick a pen in nutrient tanks. One of the best features is the ability to set the TDS ratio. This is important as PPM is calculated differently in different parts of the world. It gets very confusing. Here in the US we take the EC value and multiply it by 500 to get the PPM. So an EC of 2.0 ms would be 1000 ppm. In Europe and other parts of the world you take EC and multiply it by 700. So 2.0ms EC is 1400 (2x700). When you browse the various sites on the internet for nutrient recommendations, they are very dependent on where they are located. You can either do the math yourself or set the parameter in this slider to suit your needs. Brilliant!
