I have had positive results from having it, it keeps basic track of basic things , temp-ph- ammonia levels and send a message to cell if something is off track. I also can see par and lux readings and save . I just thought of something This is my first post in all these years...Lol...love to visit a lot...great place...
I have one and use it just for the light meter aspect. From all that I read it has a better suited to our hobbies needs optical reader, meaning it is designed for somewhat of a single point light source a apposed to the Apogee instruments wide angle optic for measuring all/ambient light available. It does a fair job in the spectral readings and Kelvin temp as long as it's not overran with typical Blue heavy LED's. I have thought it would be a good monitor for a QT system with the ammonia alert feature.
