| PRINCIPLE OF OPERATION |
|
The InfraRan Specific Vapor Analyzer is a single-beam infrared spectrometer designed specifically for easy, on-site ambient air measurements of a specific gas or gases. The analyzer can be purchased to measure virtually any compound (up to 4) that has an absorption band in the infrared region from 2.5 – 14.5 µm. The analyzer utilizes infrared absorption filter photometry as its operating principle. The integral air pump draws the sample into the cell and the sample absorbs the infrared energy from the beam. The detector measures the amount of energy absorbed at the selected wavelength and the microprocessor converts it into concentration units (ppm or percent) which are read from the analyzer’s vacuum fluorescent display. The optical filter is selected to enable the spectrometer to be specific for the specified gas. |

| LIGHTWEIGHT AND PORTABLE |
|
The analyzer weighs 18 lbs. and with its internal battery power, the InfraRan Analyzer is a truly
portable instrument. The InfraRan Specific Vapor Analyzer can run up to 8 hours on its battery pack, and includes internal data logging for added measurement and record keeping convenience. No additional equipment is necessary since all supplies that are required for monitoring are self-contained. The InfraRan Specific Vapor Analyzer can be factory-calibrated for most compounds that have an infrared absorption band in the 2.5µm to 14.5µm region.

| EASY TO USE |
| The InfraRan Specific Vapor Analyzer is factory calibrated so that no chemical standards are needed by the user to calibrate the analyzer. It’s user-friendly, menu-driven software and easy-to-read display prompt the user through all aspects of the analysis – enabling both non-technical personnel, as well as those with an infrared gas analysis background, to make fast, accurate measurements. |
|
| FAST RESPONSE |
| Response time is limited only by the sample flow through the cell. Typical initial response is 5 – 10 seconds with a stable maximum concentration in less than one minute. Since the air sample is continuously delivered to the cell by means of a built-in sampling pump, the analyzer outputs real-time concentration data, allowing personnel to be alerted to potential hazards before they become serious. |
LOW MAINTENANCE |
| The InfraRan Specific Vapor Analyzer provides a reliable, maintenance-free method for dedicated monitoring. Its design combines a hardware/electronic/software package with a measurement principle that can be easily applied to meet a variety of application needs. The analyzer does not require the use of any consumable items other than zero gas and particulate filters, which eliminates the need for purchasing a large quantity of other supplies to keep the InfraRan Analyzer operable. |
ECONOMICAL MONITORING |
| The analyzer uses a nondestructive measuring principle and only requires a source of power for operation (internal battery pack or external operating supply – 120 – 220 V AC – 50/60 Hz). Since the analyzer is factory calibrated for one specific vapor or multiple gases (depending on InfraRan model), recalibration by trained technicians is not required for most applications. With its menu-driven software, direct-reading display, and simple controls, minimal - if any - training is required to operate the analyzer. Thus, monitoring costs with the InfraRan Specific Vapor Analyzer are very low compared to other analytical methods or instrumentation. |
