This is an instruction manual that introduces the functions and operating methods of the SD-4307 Salt/TDS/Conductivity Datalogger.
The REED Instruments SD-4307 is a multi-purpose meter designed to measure conductivity, Total Dissolved Solids (TDS), and Salt. It features a real-time SD memory card datalogger with a built-in clock, allowing users to set sampling times from 1 second to 9 hours. The device supports manual and automatic datalogging modes and connects to a computer via USB/RS232 interface to transfer data directly to Excel without extra software.
The manual details the instrument's physical components, including the display, buttons, probe socket, and battery compartment. It provides step-by-step instructions for selecting measurement functions, performing zero adjustments, calibrating the probe using standard solutions, and utilizing data recording features to track maximum and minimum readings.
