The Duratech DTIR is a low cost, high accuracy single wavelength IR analyzer. It features the latest technology, and has NO moving parts that can wear out.

The DTIR has Auto - Gain for 100% transmission, and outputs % transmission on its backlit LCD display. The pulsed - sealed tungsten IR source eliminates the need for a chopping motor and prevents stray chemical vapor reactions. The thermally compensated pyro-electric detector with built-in hydrocarbon filter has an integrated temperature compensation feature. The unit preforms a self check on power up, with error messages to assist in diagnostics and repair. The standard cell holder is for cells up to 4cm, with other arrangements available, and the DTIR 970 is a 100% compatible replacement fo rthe Foxboro Miran 1FF®. There is both RS-232 and analog output on the unit as well.
