I landed on this one as it was highly recommended, so I figured why not. So I began my grow Back in Sept with this dual pen and as you can see, it's been amazing throughout the entire grow. I am about a week out from harvest. When I say she works really well, I mean she works really well! You do kind of have to get used to calibrating it but after that it's a breeze.

Only the bottom 1 inch to extend the life. If accidentally dropped in water and quickly removed likely ok. I try to only put in the probe on all my meters. **Q: Where can we buy replacement tips/probes?** A: Don't know and wouldn't buy anymore of their products. My ph pen never worked and neither did a heating pad a had gotten. Took it as a lesson, didn't even want the replacement. Went with blue lab, pricey but worth it **Q: How to calibrate temperature? My unit is reading ~8F too low** A: I tried two and both had terrible temperature accuracy. I bought a cheap $19 Taylor Precision digit thermometer which gave superior accuracy. **Q: Does this do Fahrenheit?** A: Garbage! Go with blue lab. Pricey but at least it works ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Pen Combo *by T***. on November 29, 2025* I usually use a different meter...but that one was not working (I had let it sit too long and I could not calibrate it) so I went looking for a good meter.
