Review on 🌡️ KETOTEK AC 120V Temperature and Humidity Controller Module - Digital Humidistat Thermostat Switch with Probe for Incubator Greenhouse - Programmable Regulator for Humidifier, Dehumidifier, Heating, and Cooling by Eric Basler

I bought this unit when I bought a sister dual temp unit through Vine. Not a newbie to electronics, I find it very comfortable to work with both low and mains voltage. They are almost identical in design, the only difference being the side of the sensor and the color of the display. The output stages are identical, I will explain what they mean in a moment. The input for them is 120V. I didn't really notice that when I bought it, but figured I could work with it as long as the outputs are isolated. As I found out after turning on the dual temperature controller, IT IS NOT. The outputs of these things are FULL LINE VOLTAGE. This product is not mentioned anywhere. No manual, no product photos, no location. I could have easily killed myself testing this thing while checking what's going on with the outputs and honestly it's just stupid luck I didn't. identical design, I didn't even test it. Unfortunately I waited too long to try them and the returns window is closed so this is going straight in the bin. This product is DANGEROUSLY UNSAFE. avoid it
