PH, redox, conductivity, salt, oxygen, and temperature measuring device with SD card storage (1 to 16 GB). Stored data is saved as an Excel file. The large, easy-to-read display and RS-232 interface allow for simple use. The pH meter PCE-PHD 1 is a true all-rounder for checking water quality. It is used to monitor water parameters such as pH, redox, conductivity, salt content, oxygen, and is also very suitable for temperature measurement. A 3-point calibration and automatic temperature compensation ensure high accuracy, even with fluctuating measurement temperatures. The data logger comes with a pH and conductivity probe. Various probes are available as accessories. All values can be directly saved to the SD card (1 to 16 GB) (Excel file) or transferred directly from the data logger to a PC via the RS-232 interface. We also offer optional software and the appropriate RS-232 interface cable as accessories.
