🌊 Marine ORP Monitor by American Review

Glad I got it to read ORP. It is very accurate but you need to buy other things that are recommended when using it to read the ORP in a Kangen water test compared to other bottled water.

Had high expectations and required multiple calibrations to get repeatable results from the device. I tested several items and eventually started getting consistent results that were similar. I didn't like that the unit numbers jumped between tests. I'm no expert but it's hard to believe the devices are lab quality as some others point out.

Unfortunately I kept the meter for several weeks before opening it and using it on my sewage treatment plant. It seemed to work fine for a week. Then it stopped reading accurately so I tried the calibration. This didn't work either. I turned the calibration screw fully in either direction and still couldn't change the reading depending on what environment the probe was in.

I read some reviews that the product was defective upon delivery. I haven't had any problems with mine. If handled with care, it seems to withstand months of calibration. After use, I rinse in two glasses of distilled water and clean the end of the probe with a soft toothbrush. I use this to monitor the potassium permanganate treatment in my carp pond and to confirm the water is good between treatments.

There is no doubt that antioxidants are extremely important for our bodies and with this product you can see exactly how much you are consuming! I am selling a product that makes water alkaline and releases antioxidants into the water. This product has been extremely helpful in showing people how powerful this water can be! The hardest part is the calibration. After calibration it works great! At first I thought it was a little pricey but it was definitely worth buying this product so people…

I have the same experience as the previous 1 star reviewer. The product is absolutely not working properly. Readings far, far away. The meter was taken right out of the box and freshly calibrated (and yes, I'm experienced enough to read the instructions and calibrate properly, [to the smug replyer of another 1-star review] and by the way, I don't have it understood probe cleaning cloth as indicated in the product description). The numbers were so low that I sent my water electrolysis machine…
