Both the Labspec UI and Sootspec UI Analyzers are Ultrasonic Interferometers and are very similar, however the latter is limited to engine oil soot and viscosity measurements. The Labspec has much wider applicabilities and may be used for many other different fluid systems.
Features:
Measures Sound Velocity, Temperature and Sound Transmission (inverse attenuation) at mulitple frequencies
Transmission can yield viscosity data
Concentration and attenuation data
External Probe for easy immersion directly in sample container
Probe may be inverted for fraction of milliter sample volumes
