The pHep® 4 measures pH and temperature. Thanks to a stability indicator and hold feature, you'll know when to take the reading and you can freeze the display for easy and accurate recording. A stainless steel temperature probe enables fast, precise temperature measurement and auto-compensation. Includes four 1.5V batteries, pH electrode, and electrode replacement tool. pHep 5 provides the same features and convenience, but with more precise readings (±0.01).
The NEW pH/ORP Combo measures pH, redox potential, and temperature. The NEW pH/EC/TDS Combo measures pH, conductivity, total dissolved solids, and temperature. Both have ±0.05 accuracy in their readings.
All feature automatic temperature compensation. Each also tests temperature (°C or °F) and includes a protective cap, replaceable electrode, electrode replacement tool, battery level indicator, automatic calibration, data hold feature, four 1.5V batteries, and a battery error prevention system. Each measures 1-3/4" x 6-3/4" x 3/4" thick.
Please note: While testers are automatically calibrated by the manufacturer, unavoidable jarring during shipping may affect calibration. Therefore, you should re-calibrate your tester using a Calibration Solution (sold below) prior to initial use.
When not in use, rinse the electrode with water to minimize contamination and store it with a few drops of Storage Solution (sold separately) in the protective cap.

| pH and Koi Health | | pH swings are very dangerous, as they interfere with basic body functions, leaving fish vulnerable to stress and disease. By educating yourself in the basics of water chemistry, you can help prevent disease and improve the health of your pond fish. |
| | Optimize Your Pond | | There are two ways to tell whether the oxygen level in your pond is sufficient: test and observation. Learn how to use these to provide your pond with the proper oxygen content. |
| | Oxygen Breathes Life | | Vital to its inhabitants, your pond water should always be near oxygen saturation. The key to maintaining sufficient oxygen in your pond is understanding its basic chemistry. Learn how to keep the oxygen levels in your pond at a healthy level. |
