The RTD sensor does not suffer from the cold–junction issues of the thermocouple nor the errors at high & low temperatures of the thermistor. Thus the RTD series of temperature recorders is ideal for measuring precision environmental chambers, oil baths, pH solutions, and a host of laboratory applications.
The QuadRTD and OctRTD record 4 and 8 channels, respectively. They share the powerful yet pragmatic LogMaster software which can display the units in degrees of Celsius, Fahrenheit, Kelvin, Rankine, and in Ohms. Analyses of data are quickly performed, and, for further analysis, one click will load data into an MS Excel® spreadsheet.
