Cost-effective and Versatile Multi-Gas Monitor

The INNOVA 1316-2 is a cost-effective instrument based on a rugged, reliable, and field-proven product platform. The INNOVA 1316-2 incorporates our Andros® brand of NDIR (Non-Dispersive Infrared) gas bench. Our NDIR implementation has no moving parts in the optical path, calibrations are seldom required, and the instrument automatically compensates for drift by a zero calibration routine while measurements are performed. The INNOVA 1316-2 does not demand skilled operators, consumables, or frequent service. LumaSense has many thousands of NDIR units successfully deployed for decades in harsh and demanding environments.

Similar to other Innova instruments, setup is simple, easy and fast. The INNOVA 1316-2 measures CO2 as well as the concentrations of a selection of two of the main Industrial Refrigerants (Freons). A multitude of Freons can be measured, including: R22, R134A, R404A, R407A, R407C, R410A, R422A, R422D and R507 (further Freons on Demand).. This family of instruments is an excellent complement to the ultra-low detection ranges of our existing line of Photoacoustic Gas Monitors – the INNOVA 1412i and INNOVA 1314i.

The user software BZ 6012/6013/6014 supplied with every monitor provides a user-friendly way to setup the monitor and display real time measurement data in numeric or graphical display. Large datasets can be analyzed by our software or exported to other analytical software tools.

Application scale up

For applications with multiple sampling points the multi channel monitoring LumaSoft Gas Multi Point 7950 software allows industrial manufacturers to  more easily and cost effectively monitor gas emissions by remotely controlling up to 24 Multi-Gas Monitors 1316 Series with a single computer.

The Measurement Cycle

The user software communicate with the Multi Gas Monitor - INNOVA 1316-2 using USB or RS-232 interface. The pump draws air from the sampling point through the air filter to flush out the old air in the measurement system comprising the selected NDIR module and two sensors.

Light from the infrared source is sent through the measurement chamber and passes through specialized filters and a reference filter and the absorption of energy at specific wavelengths is calculated. Then the concentration of the individual gases in the chamber is reported.

After passing the module chamber the gas is sent to the optional electrochemical sensors where the signal is measured again. The measured signal is reported back to the module and the concentration of the compound is reported together with the gas concentrations from the module via the interface connection to the software.
