Unsatisfactory

Ph monitor :( by Max

Comments: Stick with the chemicals and color charts! I've had to return two as the readings were far from accurate (readings everywhere) Calibrating isn't fun and if successful, doubtful it will hold. I would not recommend this product to my friends.

Throws off readings by RICHARD

Comments: When I connected my pH monitor to this instead of the 9V, it reads a different pH. I took a reading in the tank and it read 7.95, but then I took a sample out into a cup and it read 8.12! I put the 9V back into the meter and it reads 8.12 both in the tank and out. So, as an engineer, I figured it had to do with a grounding problem in my tank. However, I did the same experiment in a bucket. I put a small pump in the bucket and the reading dropped by 0.07. I even added a grounding strap to the bucket water, no change. So, it's a ground loop problem in the meter. You can't run the meter off the AC adapter plugged into the same outlet. I did not try to run an extension cord across the house from a different circuit, but that wouldn't be a long term solution anyway. I would not recommend this product to my friends.

Comments: I own AC Adapter Kit for each of my pinpoint meters. They work fine and are a real convenience. I only wish there was a AC Adapter for all the pinpoint meters,especially the wireless temperture controler. Another way American Marine can improve their already cost-effective products. Yes, I would recommend this product to my friends.

Not a good idea. . . by CHUCK

Experience Level: Expert

Posted on 7/13/2007 from STUDIO CITY, CA UNITED STATES

Comments: I love my pinpoint PH monitor. . . but wanted to avoid periodic replacement of the 9 volt batteries that powered it. So I ordered one of these adapters. . . and it almost destroyed the monitor. An electrically-inclined friend measured 11+ volts coming through the adapter. . . TWO successive replacement/purchases yielded similar negative results. I'd avoid this one. I would not recommend this product to my friends.
