To ensure high reliability of products, tests must be done in the production phase to detect possible errors in working mode. Because environmental testing involves long-term processes the possibility of remote observation and remote controlling of tests is very useful solution. The concept is to connect the testing chamber with a personal computer, create a reliable driver and control it remotely over the local network or Internet from other client. It is designed for performing tests on wide area of sensors and sensor based systems. Keywords: sensor reliability, testing methods, remote control, virtual instruments. 1. Introduction Reliability of developed products is important for the producer and also for the end-user of products. The number of methods and standards to determine reliability have increased noticeably. The tendency towards reliability assurance is also greater. As sensors are installed and in use in all environments and industrial areas, so the expected r
