Brief Introduction

Apera Instruments 201DJ-C Double-Junction pH Electrode is featured with a proprietary lithium glass

membrane for fast and stable readings and a double-junction structure to minimize the chance of a

clogged junction. The gel inner reference solution does not need to be refilled. This electrode is designed

for testing in complex water solutions such as wastewater and pool water as well as general water

solutions. The electrode may not work well in the following situations:

1. Long-term testing in high temperature solutions (>122°F or 60°C)

2. Frequent testing in strong alkaline (>12 pH) or acid (<2) solutions

3. Testing low ionic strength solutions like distilled or deionized water

4. Testing caustic solutions that will erode the polycarbonate housing of the electrode
