DO meter for lab research

DO ProbeThe DO-BT meter is a low cost, high accuracy approach to measure dissolved oxygen in the laboratory for scientific researchers. The DO-BT is simple to use and calibrate, yet provides high accuracy, high precision, and a wide range of measurement that is required by scientists. The DO-BT has inbuilt automatic calibration and temperature, altitude and salinity compensation features.

more information
Calibration is performed at one or two points at 0% using HI7040 solution or 100% in air.Measurements are automatically temperature compensated by using the polarographic DO probe with built-in temperature sensor. This probe features screw cap membranes for easy replacement.With a built-in logging function, measurements are stored in non volatile memory, and can be transferred to a PC through the USB port using the optional HI 92000 software and HI 920013 USB cable. The software is provided with an exclusive online guide of all the commands available and allows data printing, plotting and exporting.

The 8000 record logging interval allows the possibility of process and experimental monitoring of DO. The logging interval is automatic with user selectable intervals from 5 seconds to 180 minutes according with the speed of DO variation inside the process.

The DO-BT also provides users with GLP (Good Laboratory Practice) capabilities. GLP is a set of functions that allow the storage and retrieval of data regarding calibration. The GLP feature provides data consistency and a calibration reminder which can be set to alert the user that too much time has elapsed since the last calibration and a new one should be performed.
