PHscan Series Waterproof Pocket pH Tester

PHscan series waterproof pocket pH tester includes models 10, 20, 30 for the measurement of acidity and alkalinity in liquids. These testers are designed for outdoor applications, especially waste water treatment and environmental monitoring. Automatic Calibration: The tester allows up to three-point calibration. Press the CAL key and the display shows the standard buffer pH needed for calibration. Immerse the pH electrode into the calibration solution as indicated and press the CAL key. The tester is now automatically calibrated. Hold Function: During the measurement, hold function can momentarily freeze the reading on the display for easy viewing and recording. Automatic Temperature Compensation (ATC): PHscan30 has a temperature sensor, press oC key, the tester shows the current temperature. Automatic Temperature Compensation provide highly accurate measurements over the entire pH ranges. Replaceable Electrode: The pH electrode life is one year based on its chemical characteristics, it will influence measurement accuracy if you use it more than this time. PHscan series testers has double-junction sensor, you can easily replaced after its useful life. Auto-Power Off: These testers will automatically power down 8 minutes after the last key press. This function is helpful to save battery. It can also be turned off manually. Waterproof Feature: O-ring seals on the screw-tight battery and sensor compartments prevent water damage even if fully immersed. The unit also floats.
