Meditech MDET3 External mainstream module

Compact external mainstream ETCO2 module for continuous capnography in clinical and perioperative settings. The module uses a mainstream transducer with non-dispersive infrared (NDIR) single-beam, dual-wavelength optics (no moving parts) to deliver fast, real-time CO2 measurement suitable for adults and infants (reusable or single-patient use).

Key features

• Measurement principle: Mainstream NDIR, single-beam optics, dual wavelength
• CO2 measurement range: 0 to 152 mmHg (0 to 20 kPa)
• CO2 accuracy (temperature 35 °C):
  • 0–40 mmHg: ±2 mmHg
  • 41–70 mmHg: ±5% of reading
  • 71–100 mmHg: ±8% of reading
  • 101–150 mmHg: ±10% of reading
• Respiration rate: 0–150 breaths per minute (BPM); respiration rate accuracy ±1 breath
• Sampling rate: 100 Hz for high-resolution capnogram capture
• Fast start: capnogram displayed in under 15 seconds (ambient 25 °C); full specs within 2 minutes
• CO2 rise time (10→90% step): < 8 ms (adult and infant)
• Stability: short-term drift ≤ 2 mmHg over 4 hours; accuracy maintained over 120 hours
• Power: DC 5 V
• Physical size: 50 × 22 × 36 mm (compact module)
• Patient use: designed for both reusable and single-patient applications

Integration and application

Designed as an external mainstream module for use with patient monitors and ventilators that accept independent ETCO2 modules. Suited for operating rooms, intensive care, emergency transport and procedural sedation where fast, high-resolution CO2 monitoring and accurate breath rate detection are required.

Notes

• Some source fields (CO2 noise value, CO2 resolution and weight unit) were not specified explicitly in the available data; confirm these details with your supplier or technical datasheet before integration.
