OPSENS FIBRE OPTIC – PRESSURE & TEMPERATURE

Systems for small/medium animals – affordable, accurate, and immune to electrical interference

scientist opsens catheter

Unlike others, Opsens records from the very tip

While conventional catheters for animal-use may claim ‘tip’ sensing, transducers are generally positioned behind the tip, causing data offset and slower response.

Opsens fibre optic pressure catheters and temperature probes deliver true in-vivo pressure and temperature data from the very tip for a better signal.

CATHETER AFFORDABILTY EXTENDS OPPORTUNITIES

Opsens catheters combine precision with affordability, allowing research teams to maximise budgets without compromising quality.

ALSO FOR MRI ENVIRONMENTS

Using robust and reliable WLPI technology, the pressure catheters are MRI-compatible and immune to electrical interference, They deliver fast, reliable data in every research environment.

COMPLETE SYSTEM

Connect catheters and temperature probes to Opsens signal conditioners to view on the single or double channel monitor. Data streams directly to data acquisition software systems such as PowerLab with LabChart Pro.
