The document describes the features and characteristics of the SDL100 pH/ORP/Temperature Datalogger produced by Extech Instruments Corporation. The datalogger has a dual display for pH or mV and temperature, with automatic temperature compensation and three-point calibration for accuracy. It can store 99 manual readings and up to 20 million readings via an SD card, with real-time date and time stamping. The datalogger also has user-programmable sampling rate, min/max and data hold functions, auto power off, and built-in PC interface. It comes complete with AA batteries, SD card, hard carrying case, sample buffers, mini pH electrode, and thermistor temperature probe.
The Extech SDL100 is a portable datalogger designed to record pH, ORP (Oxidation-Reduction Potential), and temperature data. It features a large backlit dual LCD that displays both the measurement value and the corresponding temperature simultaneously.
Data can be stored on an SD card in Excel format for easy transfer to a PC for analysis. The device supports 3-point calibration, ATC or manual temperature compensation, and allows users to program sampling rates from 1 second up to nearly 9 hours.
