Infrared Transmittance Tester |
| The IRT-26 Infrared Transmittance Tester measures the 880 nM light transmittance of a sample material placed between its two probes. It provides a single, simple reading of percentage transmittance, ranging from 0 to 100%, with a resolution of 0.1%. The device is powered by an internal 9V battery, and shuts off automatically in about 4 minutes. Normal lab operation will provide years of service between battery changes. |

Features |
|
The IRT-26 features excellent linearity and stability, and good immunity to interference from ambient light an other sources. It really "just works". |

Applications
Glass Type Sensing / Glass Identification
Different types of glass can appear nearly identical to humans, but have quite different infrared transmittance properties. It can be difficult or impossible for a human operator to identify a type of glass just by looking at it. The IRT-26 allows an operator to confirm a glass type based on its infrared transmittance. This can be very useful in industrial and manufacturing applications. Suppose a window can be manufactured with two different possible types of glass, but those types are indistinguishable from each other for human operators. In such a case, the manufacturer must rely on strict control of the inventory, with no way of confirming the right part is selected. If an entire production run is produced using the wrong part, the costs can be horrific. The IRT-26 allows for confirmation of the correct part, either as an auditing device or as part of a manufacturing process.
Automotive Rain Sensors
|
Anyone involved with automotive rain sensors frequently needs to be able to determine the infrared transmittance of glass. This is because most automotive rain sensors (with our Rain Tracker being a notable exception) function over a very limited range of permissible infrared transmittance. The IRT-26 makes it easy to measure windshield infrared transmittance, either on or off of a vehicle. If you are, for example, involved in the aftermarket replacement glass industry, you can use the IRT-26 to verify a particular windshield comes close to an OE windshield in a rain sensor application. (How close do you need? You are on your own for interpreting the data!) |

Material Properties
If you are, for example, involved in producing plastic molded parts that need to block visible light but pass infrared, you need an IRT-26. Lacking such a device, you could easily make a production run of thousands of non-functional pieces.
Perfect for Qaulity-Control testing.
Other Sensing Applications
|
The IRT-26 may be used in other applications that require the precise measurement of infrared transmittance. Use it where an expensive spectrophotometer would be costly overkill. Measures at 880 nanometers, but we could adapt the IRT-26 for other wavelengths if your application calls for it. |

Gets used constantly!
Yes, this is a niche product. Being closely connected with the glass and automotive industries, and in working with infrared sensors, we found ourselves frequently needing to know the infrared transmittance of a given material. We could find no way of easily obtaining this information, so we developed one. We made this for ourselves, but ended up building many for our customers and clients who demanded one when they saw ours. If you are working in some field in which the infrared transmittance of a material is an important number, you will find this tool indispensable. Buy one!
