IR-21V Emitter (Vertical)
Boston Electronics

IR-21V Emitter (Vertical)

Regular price $61.00 $0.00

Item Description

The coiled filament of the IR-21V operates at approximately 800°C when powered with 4 watts. The radiating element is a coil of resistance wire which has a high emissivity in the infrared spectral region. The coil is supported on a cylindrical substrate of alumina.  The IR-21V has a vertically oriented coil emitter (left in picture).

Due to the reduced mass of this unit it can be pulsed at 1 hertz with a resultant
temperature variation that can be detected. The unit does not require operation in a sealed atmosphere.

Also see the Universal Photon Source (UPS) Driver Board as an accessory to your emitter.
