Gain Express orp / redox meter tester
This product works exactly as described. It works great for all my freshwater aquariums. An excellent product at a very good price. It arrived on time and in excellent condition.

Good for the price point
This is a good measuring device for someone that doesn't want to spend a bunch of money on an ORP meter however would like to know just how "charged" their health liquids (water, juices, etc) actually are. It's downside is that the measurement can sometimes take several minutes to equalize. Solid product otherwise.

Does not work has zero function as an ORP tester
The media could not be loaded. This device does not work whether it be the probe does not work or the unit is just junk. It does not read the ORP. It will continuously go up by one point as long as you leave it in the water.

Very portable
I liked the size of the tester. Not sure how accurate it is but it gives me a good idea of what the ORP IS.

Great ORP Meter. I use this frequently to measure my hydrogen water bottle function. Works great!
ORP for good Hydrogen water bottle should be between -700 to -200, and this Meter helps me monitor that. Easy to use and simple. Be careful when opening the battery compartment, the wires are short but if you are careful no problem.

Needs calibration
Nice size but never worked correctly. Needs constant re calibration using a $12 extra solution. Now don’t trust the readings. Would not recommend due to hassle involved with use.

Value for money.
I have used orp meter with several brands in the past. When i discovered a pen type orp was available. I had to get one and test it.My pool is 12,000 gallons and i just upgraded my plumbing to maximize flow rate of my ozone system. I was happy to get an accurate reading of 543 mv above the acceptable range. Thanks to this pen typeNo more guessing. I place the water sample in a glass and let the reading settle for a few minutes.The only drawback shipping is too slow.I wish the Manufacture speed up the shipping. Customers generally Don't mind paying a bit more for fast speed shipping included in the total cost.Orp levels (application)Aquaculture 150-250Cooling towers 250-350Swimming pool 400-475Hot tub 450-600Water disinfected 600
