PCE-PHD 1-LF Data Logger / Data Logging Instrument is a portable, easy-to-use measuring device with multiple capabilities for inspecting water quality. Offering extraordinary precision at an affordable price, the Data Logger / Data Logging Instrument is used for laboratory and *in situ* testing of the pH value, redox, conductivity, salt content, oxygen level and temperature of water.

Temperature compensation guarantees a high level of accuracy even with variable temperature measurements. PCE-PHD 1-LF Data Logger / Data Logging Instrument is supplied with a conductivity electrode. Additional electrodes are available for purchase separately, as is an optional mains adapter for power and a software kit with an RS-232 cable. PCE-PHD 1-LF Data Logger / Data Logging Instrument acts as a real-time data logger. All values can be stored directly on the included SD card in Microsoft Excel format or transferred to a PC by means of the RS-232 port.
