What LOTUS monitors

Precision down to 1 micron

HYDRA detects particles as small as 1 µm across multiple channels, classifying contamination to ISO 4406, NAS 1638, and GJB420B standards. Response time is 5–60 seconds per measurement — fast enough to catch transient contamination events.

  • Particle detection: 1–100 µm, multiple precision channels
  • Flow rate: 10–300 mL/min (optimised at 25 mL/min)
  • Data output: RS-485 Modbus RTU, optional 4–20 mA analogue
  • Operating temperature: −20°C to 60°C ambient, up to 80°C fluid
  • Max pressure: 2 MPa (40 MPa with pressure reducer)
  • Standards: ISO 4406, NAS 1638, GJB420B
