SE-RDA Respiratory Data Analyser

Description

Real-time recording of breathing

Quantitative measuring of mask wearer’s breathing

The SE-RDA is a portable instrument that analyses real-time respiratory flow rate and air pressure inside a respirator while fitted to a person. The device is used on location during normal work, continuously recording each breath at a rate of 50 samples per second for up to 12 hours.

Features

Captures multiple breathing parameters in real time.
Can be used to measure human breathing during any activity.
Monitoring can be done on negative-pressure masks, PAPR and breathing apparatus.
Does not affect breathing resistance or interfere with the airflow through the mask.
No advanced technical skills required.
Powered by three AAA batteries.
Can be connected to Sundström masks without any permanent modifications.
Can assess the performance of Powered Air-Purifying Respirators (PAPR).

Description: The SE-RDA is a portable instrument that analyses real-time respiratory flow rate and air pressure inside a respirator while fitted to a person performing normal work routines
Range of devices: Can be connected to negative-pressure devices with filters and positive-pressure respirators such as Powered Air-Purifying Respirators (PAPR) and breathing apparatus. Can be connected to Sundström full face and half face masks without any modifications
Sampling: Captures multiple breathing parameters in real time at a rate of 50 times per second for up to 12 hours
Software app: Comprehensive software app included. The app enables the user to determine:
- Minute volumes (averaged over an entire shift or selected periods)
- Total volume breathed
- Peak inhalation flowrates for all tasks performed during the period
- Breathing Resistance (BR) and Work of Breathing (WoB) for various types of RPD
- ISO Work Rate classification (W1 – W4) and how the work rate varies over the period
- The amount of time the respirator is worn during the shift.
Battery: 3 x AAA batteries
Dimensions: 127H x 78W x 26D mm — pocket clip on back. Connectors extend approx. 8 mm from housing
Weight: 126 g
