The new testo Saveris measurement system measures temperature and humidity values in the environment and in processes.The easy-to-use measurement system delivers safety and time savings thanks to automated measurement data recording.
testo Saveris is ideal for
· the monitoring and documentation of temperature or humidity data in production, quality assurance and R&D as well as in buildings
· monitoring of the storage climate of temperature and humidity-sensitive products, such as valuable inventory (museums, server rooms), of medicines and of foodstuffs
· and monitoring of the foodstuff cooling chain.
The testo Saveris radio probes measure temperature and humidity. In the measuring cycle, the probes save their measurement data and send it to the central base at regular intervals. If a limit value is exceeded, a radio link is established immediately. Through bidirectional transmission, the radio probe and the base are in mutual contact. This therefore ensures that the measurement data is only recorded by the base and is not interfered with by other radio systems.
An alarm sounds in the event that the radio link is interrupted by obstacles. The memory in the probe ensures that the measurement data is not lost in the event of an interference in the radio link.
In free field, the transmission path is approx. 300 m at a frequency of 868 MHz and approx. 100 m at a frequency of 2.4 GHz. In buildings, the transmission path is strongly influenced by structural conditions such as walls, refrigerator doors or metal doors. The radio link can be improved or lengthened with poor structural conditions by using a router. Probe versions with internal and external sensors allow the adaptation to every aplications. The radio probes are available with or without a display as an option. Current measurement data, the battery status and the quality of the radio link are shown on the display.
In addition to the radio probes, probes can be used that are directly connected to the Ethernet. The existing LAN infrastructure can be used through this. This allows the data transfer from the probe to the base, even over long distances. Ethernet probes can be used over any long periods since they are connected to the mains and therefore work independently of batteries. The internal memory guarantees that the existing measurement data is not lost, even with failure of the mains or the LAN connection. A display informs about the current measurement data as well as the probe status. Through the connection of a converter to an Ethernet jack, the signal of a radio probe can be converted into an Ethernet signal.
The base is the heart of testo Saveris and can save 40,000 readings. An emergency battery ensures that an alarm is transmitted and that no existing data is lost in the event of a power failure.
The system data and alarms are visible via the display of the Saveris base. Even without the PC running, the base issues an alarm by means of an LED if the limit value is exceeded, or optionally via SMS.
In total, a base can incorporate 150 radio and Ethernet probes or 450 measurement channels. The Saveris base is connected to the PC either via USB or Ethernet cable. The Saveris base thereby offers flexibility with the highest data security.
The measurement data is transmitted from the base to a PC on which the testo Saveris software is installed. All measurement data is saved centrally in the software's database and can be called up any time as a table or a graphic. All alarms that occur are listed in a table as a history.
The automatic creation of PDF reports in defined intervals also simplifies the documentation. Using the calendar function and the consolidation of probes into groups, the operation of the software is simple and intuitive. In the event of an alarm the user can choose between receiving a message via e-mail or a pop-up directly on the screen.
