Description

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.

Big Bang for the Bucks! by BARAN GALOCY Experience Level: Expert Posted on 5/6/2008 from REDDING, CA UNITED STATES Comments: 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.
