Micro Heaters

For use in devices necessitating a small but accurate heat source with precise temperature control.

Can be customised to fit specific application requirements.

Thermal Infrared Emitters

Miniaturized infrared sources in SMD housing (HISsmd series)

For use in miniaturized gas sensors.

Low energy consumption, high efficiency and small size make them a perfect fit for portable and battery powered applications.

Black-body infrared sources in TO39/TO5 package (HISbasic series) 

High efficiency and optical output power is achieved in these emitters by using an integrated gold-plated reflector to direct radiation emitted from the rear to the front.

High-power infrared sources in TO-8 housing (HISpower series)

These emitters achieve maximum efficiency by using an integrated gold-plated reflector to direct radiation emitted from the rear to the front through the housing window.

The new SFS Flow Module is a ready-to-use, linearized mass flow module for gases

The SFS Flow Module is primarily used in gas supply, gas dosing systems, analyzers and manifolds, but is also suitable for process control, e.g. in modified atmosphere conditions for the measurement of low flow rates.

This makes this flow module ideally suited for integration in medical devices. In environmental technology the SFS module can be used in measuring instruments for gas analysis and for continuous emission monitoring.

Thanks to its bi-directional calorimetric measurement, the SFS Flow Module provides fast, continuous gas flow monitoring with a response time ≤ 20 ms. It comes factory-linearized with a repeatability of 0.2 % and an accuracy of up to 2 % f.s. and is available in three versions for different flow rates +/-50 sccm, +/-200 sccm and +/-1000 sccm.

The flow module has both, an analogue and a digital I2C output and is equipped with two address pins. Another advantage of the new SFS Flow Module is its compact design. With an installation space of only 50 x 40 x 20 mm, it is sufficiently small for integration into a measuring unit.
