D-Tek CO2

The D-TEK CO₂ uses an innovative infrared absorption sensing cell which is extremely selective to carbon dioxide, yet its circuitry allows the instrument to equalize to the CO₂ present in the atmosphere, so there is minimal risk of false alarms. D-TEK CO₂ maintains its sensitivity over time for consistent, accurate and reliable performance. Its specialized infrared sensor cell lasts for approximately 800 hours, so you buy fewer replacement parts.

Additional features include a charging status indicator, sensor failure indication, sensor test mode and rechargeable NiMH (nickel metal hydride) batteries.

Features at a Glance

• 6 gm/year sensitivity
• Low risk of false alarms because it equalizes to the CO₂ present in the air
• 800-hour infrared cell life for low cost of ownership
• Consistent and accurate response because the infrared cell does not weaken over time
• Will not react to smoke, humidity, airflow or temperature changes
• Quick response and quick clearing (""zeroing"") from high-efficiency air sampling pump
• On-board diagnostics indicate charging status and warn of low battery or infrared cell failure
• NiMH power stick won't corrode and provides greater charging capacity
• Hard plastic case, NiMH power stick, 12V and AC adapter/recharger, tip filters and infrared cell included
