Hanna Waterproof Combo pH and ORP Tester

Hanna Instruments Combo series waterproof tester designed for simultaneous pH and ORP measurements. 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.

HI98121 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.
