The newest member to HANNA® 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.
