Report on the performance testing of the Serinus 30 ambient air quality
monitoring system manufactured by Ecotech Pty Ltd measuring CO, Report
EP_Ecotech_Serinus30_en.docx
6.1 4.1.7 Data output
The output signals shall be provided digitally (e.g. RS232) and/or as analogue sig-
nals (e.g. 4mA to 20 mA).
6.2 Equipment
PC and network connection
6.3 Testing
The measuring system is equipped with RS232, USB, 25-pin digital and analogue in- and
outputs, TCP/IP Ethernet network connection (optional) and Bluetooth. Moreover, it has a
means to output analogue signals (max. 3 analogue outputs).
6.4 Evaluation
Measured signals are output at the back of the system as follows:
Analogue: 0 – 20, 2 – 20, 4 – 20 mA or 0 – 5 V, selectable concentration range
Digital RS232, USB, 25-pin digital in- and outputs, TCP/IP Ethernet network
connection (optional) and Bluetooth
6.5 Assessment
Measured signals are provided in analogue (0–20 mA, 2–20 mA, 4–20 mA or 0–5 V) and dig-
ital form (via TCP/IP, RS 232, USB; Bluetooth).
It is possible to connect additional measuring systems or peripheral devices via the respec-
tive ports (e.g. analogue inputs).
Does this comply with the performance criterion? yes
