FIX800 VOC Gas Detector Installation at a University Research Laboratory in Seoul

A university research laboratory in Seoul requested the installation of the FIX800 fixed-type VOC gas detector along with the Shumia R9600 data logger unit within the same calendar year. The installation team coordinated the schedule promptly and completed the full installation, wiring, software setup, and user training on December 27th. The system was deployed inside the laboratory fume hood to enable continuous 24-hour VOC concentration monitoring and structured data export to Excel for ongoing research documentation.

Installation Specifications

Key Considerations for VOC Monitoring in Research Laboratory Environments

• The FIX800 sensor is mounted at the bottom of the detector housing; multi-gas (composite) configurations use a larger PCB housing, so the enclosure footprint differs from single-gas models — verify physical clearance inside the fume hood before installation.
• The FIX800 does not support on-board data extraction independently; pairing it with the R9600 data logger via a 4-20 mA wired connection enables real-time data visualization and timestamped 24-hour logging.
• Logged measurement data can be exported directly to Excel format through the R9600 companion software, facilitating integration into laboratory research records and compliance documentation.
• RS485 Modbus RTU communication is available for facilities requiring integration with a PLC or building management system, and the vendor provides full protocol and Modbus communication data sheets.
• Prior to installation, site preparation should include: confirming the sensor mounting position within the fume hood, planning the communication cable routing from the detector to the data logger, and ensuring the connected PC or laptop has the R9600 software installed and properly configured.

Frequently Asked Questions

What does the FIX800 measure, and what is the detection range in this installation?

The FIX800 is configured to detect VOC (Volatile Organic Compounds) with a measurement range of 0–1,000 ppm. It is a fixed-type wall-mount detector designed for continuous monitoring in enclosed environments such as laboratory fume hoods.

Why was the Shumia R9600 data logger required alongside the FIX800?

The FIX800 outputs a real-time analog reading but does not have a built-in capability to store or export data independently. The R9600 data logger receives the 4-20 mA signal from the FIX800 via a wired connection and stores measurement data continuously, allowing the research team to export 24-hour logs to Excel format for analysis and record-keeping.

What communication interfaces does the FIX800 support for integration with external systems?

Beyond the 4-20 mA analog output used to connect to the R9600 data logger in this project, the FIX800 also supports RS485 Modbus RTU communication. This allows the detector to be integrated with PLCs or building automation systems; protocol documentation and Modbus communication data sheets are available from the supplier.

What is involved in the software setup for the R9600 data logger?

The R9600 requires dedicated companion software to be installed on a connected PC or laptop. During this installation, the software was configured on-site, the 4-20 mA wiring was verified, and real-time data transmission from the FIX800 to the laptop was confirmed. The end user was also trained on how to restart the software after a laptop reboot and how to export logged data to Excel.
