Quickly measure pH and temperature; or test conductivity, total dissolved solids, and temperature
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. ±0.1 accuracy.
The DiST® 5 offers a 3-in-1 solution that instantly tests conductivity, total dissolved solids (TDS), and temperature. The unit includes adjustable TDS ratio and temperature compensation. These testers also feature a stability indicator and hold feature - you'll know when to take the reading and you can freeze the display for an easy, accurate recording. A stainless steel temperature probe enables faster, more precise temperature measurement. Includes EC/TDS Probe, four 1.5V batteries, and electrode replacement tool. ±0.01 accuracy.
pHep 5 and DiST 6 provide the same features and convenience, but with more precise readings (±0.01 and ±0.02).
The pH/ORP Combo measures pH, redox potential, and temperature. The 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 separately) 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.

Complex systems like marine or reef aquariums may require more tests, but careful testing helps you maintain ideal water quality crucial for the success of these sensitive systems. Hanna Testers are available to test many marine water parameters.
With tasks that are crucial yet routine, such as measuring temperature and pH, many hobbyists opt for electronic monitors that combine and automate these two functions. These precision devices continually display readings on an LCD screen.
Please note: Return of electrical equipment to Drs. Foster & Smith for exchange or refund is limited to 60 days from the date of purchase. Beyond 60 days, please contact the manufacturer for repair or replacement as covered by the manufacturer's warranty.
