No more mixing solutions, or waiting - simply dip these waterproof testers in the waterEasy-to-read test results in secondsQuickly measure pH and temperature; or test conductivity, total dissolved solids, and temperatureThe 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 (s
