Hydrophone: The Müller-Platte Needle Probe
The Müller-Platte Needle Probe was invented at the University of Aachen 1985 for measurements of low energy water shock waves for developing the kidney stone lithotripter and for focusing ultrasound waves. This special micro gauge based on pvdf is designed for high-energy ultrasound measurements as well as for recording blast waves in water up to some kbar. [read more]

NEW: Optical Hydrophone
This is a robust, large-bandwidth membrane-free hydrophone. Designed for ultrasound sensing in the Pa to MPa regime. It is particularly suited to the characterization required for medical and industrial ultrasonics equipment. Using patented technology, the sensor is immune to damage from high pressure amplitudes. It offers superior measurement bandwidth in a small form factor. [read more]

Pressure Measurement in Liquids and Gases
We offer two piezoelectric probe types. On the one hand the Müller-Platten needle probe, the gold standard for water impact measurement with a rise time of 50 ns, known for the measurement of kidney stone crushers or similar. And the fast M60-1L and M60-3L pressure probes as well as the M60-3 and M100-1 probes for use in gases.

Pressure Evaluation: FUJIFILM PRESCALE
The ability to measure surface pressures and pressure distributions with the unique Fuji pressure sensitive film has been available for more than 30 years. The FujiFilm Prescale can be used almost in all sorts of measurements of surface pressure indication, or simply to show the pressure distribution. The pressure indicating films may be used both in air and in water. [read more]

Electronic Pressure Films
In the electronic surface pressure measuring Sensor Products Inc. is our partner for many years. SPI is in the U.S., the long-standing expert in the field of surface pressure measurement. Tactilus® is matrix based tactile surface sensor that works by the principle of piezoresistance can be placed as a thin mat between all bodies.

Temperature and Heat Flux Measurements
We offer two unique solutions for this. One is the robust Thermocouple with respond times of only a few micro seconds, which can be mount seamless into the model surface. Our Nickel-Thin-Film Thermometer is highly sensitive with a short respond time as well and easy to connect via embedded wiring.

Heatflux Film THERMOSCALE – Easy Made Surface Heat Flux Evaluation
With the new film "Thermoscale", a temperature measuring film, we are expanding our product range to include a film that does more than measure the temperature. Thermoscale measures the heat flow. A heat flux is composed of the parameters of temperature and time. At the same time, a uniform contact pressure must be ensured. [read more]

UVSCALE – Ultraviolet Light Amount Distribution Measurement Film
With the new Fuji film UVSCALE Müller Instruments expands his product range to another measuring film that can measure the amount of UV light depending on the source in the range of 4 - –100.000 mJ/cm² in a wave length range from 200 to 420 nm.

Peripheral Devices
For all our pressure and temperature sensors we provide high frequency amplifiers. The pressure sensors can be connected to a charge amplifier with 10 MHz bandwidth to drive very long cables up to 150 m. For the heat flux and thin film sensors we offer an amplifier with 1 MHz bandwidth and sensor power supply. [read more]

Explosive Testings
Together with our partner OZM we provide special instruments for testing of energetic materials. The manufactured instruments cover testing of stability and compatibility, sensitivity and explosive performance of energetics in various testing programs including detonation chambers.
