Total Enthalpy Probes
![P_20181019_160622]( "P_20181019_160622")
These special probes have been designed for total enthalpy measurements in reactive gas flow.
Moreover these probes, appropriately instrumented, can measure many other quantities of interest
in reactive gas flows, such as velocity, chemical composition and total pressure.
Heat Flux-Temperature Probes
![SFERA1]( "SFERA1")
Most of the thermocouples installed in slug sensors are manufactured by Astra.
We are also able to supply thermocouples for any application and temperature range.
Temperature and heat-flux sensors can be integrated into probes of any shape and size.
Multiple-sensor Probes 
Complex, multiple-sensor Probes, equipped with temperature, heat flux and pressure sensors can be
manufactured by Astra on custom design, including probe supports and thermal protection devices
for thermally critical areas of the probes themselves.
Heat Flux Sensors
Astra manufactures many types of slug sensors, both standard and custom designed.
Astra is also able to select and supply many other sensors, including Gardon sensors,
Schmidt-Boelter sensors, thermopile sensors and others.
Hypersonic Facilities
Astra design and manufacture hypersonic facilities based on industrial components, minimizing complex and expensive
"ad hoc" systems and overcoming the problems of reliability and low productivity typical of hypersonic wind tunnel.
based on customer requirements and the results of a proprietary software, Astra sets the technology
and the design of the facility (Torch type, chamber pressure, nozzle design, instrumentation).
Astra builds the facility, demonstrates the system’s performance and assist the customer
with process parameters and diagnostic tools setting.
