Analyzing Medical Gases with Handheld Oxygen Analyzers

The AII-2000 range or Palm O2 handheld oxygen analyzers from Analytical Industries offer a straightforward means for verifying oxygen and other medical gases used in medical or veterinary clinics. These low-cost, FDA-approved medical gas analyzers are equipped with sophisticated, maintenance-free galvanic oxygen sensors and can operate for up to 32 months.

With decades of expertise in the design and production of oxygen instrumentation for respiratory medical devices, both models have been particularly developed for the spot checking of oxygen levels in incubators, intensive care, anesthesia, or other variants of respiratory or oxygen therapy:

  • Maintenance-free oxygen sensors
  • Integral or remote sensor options
  • Very easy to operate
  • Long battery life: up to 18 months of continuous operation for AII-2000 Palm O2
  • O2 range of 0%–100%
  • Sensor lifetime of up to 32 months
