Infrared Industries makes available its industry-leading NDIR optical benches for custom uses, including integration into OEM gas analyzer systems. We offer a wide range of abilities and features including custom detectors and filters, custom samples cells and sources, as well as custom materials and mechanical designs. Infrared Industries was the initial supplier of benches to the top automotive manufacturers in the 1970s and has built upon that technology to offer you gas analyzer component products that fit a wide range of needs.

The IR-510 NDIR Optical Bench offers greater design flexibility to OEMs due to its small overall size and low power consumption, combined with our ability to customize subsystem designs to your specifications. The enhanced optics and electronics dramatically reduce zero drift after the initial warm-up period. Temperature and pressure compensation eliminate the major causes of span drift found in many other NDIR instruments.

The IR-510 can fit a wide variety of enclosures. The software and communications protocol are designed to make system integration simple and fast. The command set has the flexibility to provide a variety of output configurations including pneumatic controls, printers, measurement data, and selected displays. The system monitors and corrects for critical operating parameters that affect performance and provides real-time status of the overall integrity and quality of the gas measurement.

Portable applications can be satisfied by populating the battery slot. The IR-510 interfaces with analog outputs and to a PC for complete control, display, and graphing capability. Recording of the output data within the bench itself allows the measurements to be replayed and analyzed at a later time.

The IR-510 also has a protected detector for accuracy and long life, integrated DC pump and solenoid drivers, graphic LCD driver, quick-clean sample cell design, and is DC powered and portable.
