DESCRIPTION

The HI7021L is a high-quality ORP test solution made from reagent-grade chemicals and is used to test platinum and gold ORP electrodes. Hanna test solutions have the lot number and expiration date clearly indicated on the label and feature an air-tight, tamper-evident seal to ensure solution quality.

Prepared with reagent-grade chemicals
Allows for quick verification of your ORP electrode
Air-tight seal to ensure solution quality

The HI7021L is an ORP test solution designed to assess the performance of ORP electrodes. When the ORP electrode is placed in the test solution, the reading should be within ±20 mV of the value of 240 mV @ 25°C. This solution allows users to quickly determine if their electrodes are reading correctly. Using a diagnostic tool, users can then decide whether the ORP electrode needs cleaning and conditioning. The test solutions are produced in our state-of-the-art manufacturing facility using reagent-grade chemicals in a temperature-controlled environment.
