pH/ORP Tester: HI 98121

pH and ORP Tester

Simple to Use
Highly Accurate
Floating and Waterproof Body

The Combo series of combination waterproof testers with advanced functions now includes the new model HI 98121 for simultaneous pH and ORP measurements. HI 98121 also reads temperature, which is continuously displayed on the dual level LCD. The pH electrode fiber junction can be easily pulled out for replenishment. The pH electrode cartridge can be quickly replaced with the supplied electrode removal tool. The encapsulated external stainless steel temperature sensor provides a fast response due to its close proximity to the pH electrode. The HI 98121 works with common batteries and displays the percentage of battery life remaining when turned on. The stability indicator ensures reliable readings.

HI 98121 is supplied complete with protective cap, electrode removal tool, batteries and instructions.
