Description
- The Dräger Ammonia 2/a detector tube accurately measures ammonia (NH₃) concentrations in air and technical gasses, making it ideal for workplace and industrial monitoring.
- Measuring range: Offers a standard measuring range of 2-30 ppm with 5 pump strokes and a measurement time of about 1 minute.
- Clear visual indication: The indicating layer changes color from yellow to blue, allowing the ammonia concentration to be directly measured using the graduated scale on the tube.
- Reliable measurement: Has a standard deviation of ±10-15% under specified conditions.
- Suitable operating parameters include temperatures of 10°C to 50°C and absolute humidity of less than 20 mg H₂O/L.
- Simple on-site testing: The factory-calibrated tube is compatible with Dräger tube pumps, including the Dräger accuro, and allows for convenient spot readings in the field.
- Professional applications include workplace air investigations, technical gas analysis, compressed air and gas measurements, leak detection, concentration peak identification, and air-quality assessments.
- The detection principle is as follows: Ammonia interacts with a pH indicator in the tube, resulting in a blue reaction product that indicates the detected concentration.
- Cross-sensitivity: Other fundamental chemicals, such as organic amines, may also be detected. Dräger states that at the specified conditions, 300 ppm nitrous fumes, 2,000 ppm sulfur dioxide, and 2,000 ppm hydrogen sulfide have no effect on the indication.
