“Bio-cleanness sensor” – H2B™

H2B is a non-contact optical sensor for point detection of microbial contamination on various solid surfaces in security, safety and medical applications where surfaces are exposed to accidental, natural or intentional contamination.

It serves as a selective point inspection tool for bio-cleanness control and assessment of the decontamination efficiency, which is commonly quoted as “how clean is clean enough”.


  • Non-contact point detection of microbial  contamination on the surfaces
  • Decontamination control
  • Instant response
  • Robust design for on-site use
  • No sampling, no consumables
  • WiFi connection for external data logging
  • Integration in sensor network is possible

BlueHawk™ – “Keep the seas blue”

The BlueHawk sensor is aimed for detection of oil films on water and ground surfaces in continuous unattended mode. It registers the specific fluorescence of oil caused by its exposure to certain ultraviolet light emission. Due to that the sensor is selectively sensitive to various oil products while not reacting to most other materials that may appear in the observation area. When the oil is detected the system generates ALARM delivered to the control terminal station according to installation structure. Sensing, processing and alarming are done in real-time.

The sensor is assembled in a weatherproof housing complying with IP68 standard and includes electronics and communication means providing all-sufficient operations as a stand-alone or network unit. It is designed for continuous unattended operation in the risk areas for oil leak in the water or on the ground, including industrial plants, oil storage terminals, waterways, harbors, and other sites of environmental concern.


  • Non-contact detection of oil products in water and on ground
  • No false alarms caused by other than oil objects
  • All weather design
  • Applicable in hazardous locations
  • Low weight and power consumption
  • Adjustable pollution threshold to filter out minor detection events
  • Remote access to setup operational parameters
  • Operates as a stand-alone or network unit
