PH Meter & TDS Meter Digital Water Tester 5 in 1 Salinity Tester PH Temp EC and TDS Meter,PH Meter for Water with LCD Backlit,Water Testing Kits for Drinking Water,Wine,Swimming Pool,Hot Tub Spas.

I got it calibrated and it works great. I have a well and a RO unit. This unit is very accurate reasonable price and it came on time.

Easy, inexpensive way to test the quality of your water. We have an issue with cloudiness and sedimentation after the city flushes the lines or uses a hydrant, and even thought they tell me it's perfectly safe, is feel better knowing I can quickly check for myself. This is easy to read, checks for several different issues that might be present, as well as reads temperature. We'll also end up using it for the pool which is an added bonus. Comes with packets that help you calibrate and check accuracy.

Bought for a water professional. The meter itself works really well, luckily we have a few technicians on staff that already had something similar because the calibration instructions left a lot out.

This thing is trash. I gave it 5-stars so that this review would be seen by more customers. It’s trash. The user manual is trash, the meter is trash, the company is trash. Save your money and buy a meter that costs at least $100 or you’re literally just wasting money. Maybe go to your local pool supply store and see if they have one that they also sell the calibration solutions for. This product is complete garbage.

This has been a great purchase. No more vials with chemicals to mix in. Simply place it in your water sample and you have your results in seconds. High quality, accurate, inexpensive, easy to use handheld or connect it to your phone. The most difficult part is calibrating.

Calibration is a pain but, you get what you pay for. If all your looking for is pH and temp, your good.

This has been working out great for me. Accurate PH.

I like it a lot. Works well. Will buy again once this one goes bad.
