The iSense sampling Data Logger is designed for both permanent and temporary installations in industrial settings. It features a built-in gas sampling pump, internal memory for data logging, a relay and outputs for level control. Use it for:

  • Process Monitoring and Control
  • Packaging with N2 or CO2 flood.
  • Oxygen depletion alarm and or control
  • Long-range Data Collection
  • Temporary Sampling Inspections
  • Remote Deployment in Industrial Settings

To maximize connectivity, the iSense features a M12 (12-pin) connector for RS-485, 4-20mA loop output, a 1A 30VDC (NO/NC/COM) relay and connection to a 24VDC power. These inputs and outputs allow for easy interfacing with existing PLC and RS-485 MODBUS capable data networks. The NEMA 4 / IP-65 rated enclosure makes it suitable for permanent wall-mounted industrial applications.

Inside the iSense  is a instrumentation pump connected to two tube ports on the side of the unit. When the unit is operating, the pump draws gas from one tube port through the O2 sensor and exhaust it from the other. By connecting tubing to the inlet, you can remotely sample gas. By connecting tubing to both ports, you can create a closed-loop system and return the gas back to the original container. This makes the iSense perfect for measuring potentially dangerous high concentrations of O2 in biological applications, or for small volume head space measurements.

In leak detect mode, the display change colors when O2 concentrations go over or under a programmable level. This settings can be changed in the software.

Free Easy-to-use GasLab® Software 

This device uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.
