Common manual for quick start of all Sxxxx, Rxxxx data loggers
Temperature operating range of hygrometer S3121, R3121
Data logger accessories
Included is traceable calibration certificate from the manufacturer, instruction manual.
Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.
For basic use it is necessary to order at minimum a COM adapter or USB adapter for
communication with computer, optionally a start/stop magnet, if needed to control data logging
the other way than directly from computer.
Anytime it is possible to download free basic Windows program for hygrometer . Program enables to control all data logger functions and viewing and printing of record in numerical and simple graphic format. It is possible to export humidity and temperature values to dbf or txt formats for further analysis.
