Stethograph 

The stethograph can be used with the Pressure (Differential ±15 kPa) sensor  or the  Pressure (Differential ±1 kPa) sensor and an accessory pack to measure the breathing rate.  A velcro strap attaches a small airbag around the subjects chest. Datadisc can then graph the resultant variations on pressure in the sac as breathing rate. 

The data below relates specifically to the Pressure (±15 kPa Differential) sensor, .

1. Logger compatibility :ScienceScope Type 2 (Click for details)

2. range ±15 kPa or the range ±1kPa
3. resolution 0.02 kPa or resolution 0.0015 kPa
4. maximum recording frequency with Datadisc is 10 milliseconds
