Great product Tyler recommended easy views accurate no guessing

Great customer service.

The olive oil acidity tests are easy to use and are an affordable option for our small start-up facility.

Very happy will do again

Disappointed that chlorine checker was constrained to upper value of 2. 5 ppm, which was not useful for pool water testing

Received everything just as ordered. Simple and make it easy to zero in and maintain correct chlorine dosage and carbon filtration for stinky well water treatment. Up to now it has been hit and miss, mostly miss.

Couldn't ask for better service. Fast shipping and competent people. When I had questions, they had answers! Thank you!

GOOD SUPPLIER AND PRODUCTS

great

I like it ok. Time will tell

Very easy to perform and very accurate

great

Very good range of instruments particularly for field studies. I use them frequently

Using Multi parameter Meter…. has remained reliable and accurate for 4 yrs now.

I love and trust the Hanna checkers, PH meter and reagents.

My orders have always been delivered on time and with exactly what I ordered. I have needed assistance in the past with procedures and getting new instructions booklets and the tech support was great. I love the aquarium product line, and it is a top seller in my retail store.

Great product, reliable and easy to use

I am having an issue with the phone holding calibration. I have recalibrated the unit 4 times in the past few weeks. Not sure if it’s the probe or the unit itself. Salt reading is fine but Ph slowly drops from 8. 2 to 7. 4. I have another probe in my calcium reactor connected to. Milwaukee unit so I know the water is fine. Please advise.

Great product and very easy to use!!

The alkalinity tester es great. The nitrate and calcium ones need to be simplified
