This item has been discontinued.

Hanna Instruments The newest member to Hanna instruments Combo series of combination waterproof testers with advanced functions is HI 98121, designed for simultaneous pH and ORP measurements.

HI 98121 also reads temperature, which is continuously displayed on the dual level LCD.

An encapsulated external stainless steel sensor, positioned in close proximity to the pH electrode provides fast response. A fiber junction can be easily pulled out and replenished. And when finally spent, the pH electrode cartridge can be quickly replaced with the supplied electrode removal tool, reducing waste and cost.

HI 98121 works with common batteries and when turned on, displays the percentage of remaining battery life. The stability indicator ensures reliable readings.

Ergonomically designed for ease in handling, this meter will float if inadvertently dropped into water.

*Please note: pH calibration is required prior to use.  ORP comes pre-calibrated straight from Hanna Instruments.

“Hanna PH & ORP Tester”

I have used this product in 2009 and I was happy with it. The instrument broke down on me after a long while because of no maintenance, I guess. (I really didn't know if there was one at all). So I upgraded to a PINPOINT ORP Monitor which is very cumbersome to use. Many times I knocked down the ...Read More

I intended to use it during product presentations going from one glass of water to another testing the ORP. But it takes too long. I had seen another unit work much faster. I am not sure at this time if I will continue to use this unit or find the name of the other and go that way.

“Big Bang for the Bucks!”

I bought this device to definitively prove the difference between regular drinking water and ionized drinking water, as I distribute Tyent water ionizers. People are fascinated by the negative ORP value that the Hanna tester demonstrates. The PH meter is equally useful, as ionized water has a ...Read More
