Riken keiki ri-413A halocarbon ndir portable analyzer
Riken Keiki Halocarbon Indicator for measuring ppm concentration of the 7 gases above as mentioned in the sub-title of this ad. It also can be used to measure other halocarbons such as perchloroethylene, etc. This analyzer is almost new. Made in year 2004. Has audible alarm. zero and calibration pots, gas select buttons. Very easy to use with operating and calibration instruction on the carying case. Operate on D-cell batteries (included), or nickel-cadmium D-cell-rechargeble batteries (not included), or AC/DC 8 Vdc charger (not included). Has 0-100 mVDC output for recorder. This is a non dispersive infrared analyzer (NDIR) which is a permanent sensor/cell. The unit was tested with gas and is in good working condition. HAs sample hose but missiing the plastic probe tip assembly (filter).
Riken Keiki still sale the unit. See the following website for more information: http:// /pages/ri413a.htm
* Measurement of Instantaneous concentration for 7 kinds of halogenated hydrocarbon vapors
* Measurement of average concentration over 1, 3 or 15 minutes
* Adjustable alarm point from 0-full scale
The Model RI-413A utilizes non-dispersive infrared absorption (NDIR) technology as a convenient and inexpensive solution to the problem of measuring for halocarbon vapors like R-11, R-12, R-22, R-113, R-114, R-502, and R-134A. By combining the versatility of a microprocessor and the selectivity of a non-dispersive infrared analyzer, RKI provides a compact and inexpensive halocarbon monitor for daily use in industrial safety and atmospheric control applications.
Each halocarbon is characterized by the amount of infrared energy the gas can absorb. Inside the Model RI-413A, a small pump continuously draws a sample of the atmosphere to be tested, through a length of hose and into an infrared chamber. The infrared ray is alternately transmitted through this chamber measuring the amount of energy passing through. As a result, the halogenated hydrocarbon vapor content is continuously monitored and digitally displayed directly in PPM units, to the nearest 25 ppm.
The microprocessor control provides easy to follow operational and malfunction instructions. Simple, reliable operation makes the RI-413A the smart choice for portable monitoring of halogenated hydrocarbon vapor levels.
Non-dispersive infrared absorption (NDIR)

The infrared analyzer uses the fact that each gas absorbs infrared energy at a characteristic frequency. In the gas analyzer an infrared source (an electrically heated wire) emits a broad band of energy which is focused on a solid state detector through a narrow band filter selected to transmit only a certain range of frequencies which are selectively absorbed by halogenated vapors. A sample of the gas to be detected flows through an enclosed chamber interposed between the infrared source and the detector.
The infrared ray is alternately transmitted through this chamber. If the measuring chamber contains halogenated vapors, the amount of energy passing through the chamber is less than it would be without the halogenated vapors present. A comparison of the two levels of energy is an indication of the concentration of halogenated vapors in the sample.
