- Mainstream or sidestream. Mainstream sensors sit on the airway adapter and respond fast; sidestream sampling suits small patients and non-intubated animals. VET-ET31 ships with both.
- Stand-alone or combined. VET-ET10 adds EtCO₂ to any setup; VET-ET31 also measures SpO₂ and pulse rate, with species settings for cats, dogs and horses.
- Alarms. VET-ET10 has audible and visual alarms for over-limit values, adapter off and low battery.
- Already have a monitor? VET-VE7 offers EtCO₂ as an option, see our veterinary monitors.
Veterinary Capnograph FAQ
What does a veterinary capnograph measure?
End-tidal CO₂, the CO₂ level at the end of each breath, which shows ventilation status under anesthesia.
What is the difference between mainstream and sidestream?
Mainstream measures at the airway adapter; sidestream draws a gas sample through a tube to the monitor. VET-ET31 supports both.
Does it need calibration?
The VET-ET31 CO₂ module uses dual-wavelength measurement and needs no calibration.
What is the warranty?
VET-ET31 and VET-ET10 come with a 1-year warranty.
What are the MOQ and lead time?
MOQ is 1 unit and lead time is 5–10 days. OEM branding is available.
