Detachable flow heads in the TSD237 Series are machined from acetal to give good stability with low weight and have found application in pediatrics and in the respiration measurement of animals such as dogs, cats, rats and mice.
Condensation from expired air can be a problem with pneumotachographs. This can be prevented by fitting a non-return valve and measuring only inspiration or alternatively by heating the flowhead, but viscosity errors may arise which, in the first few breaths especially, preheat the inspired air most uncomfortably. In this range of flow heads, the problem is approached from a fresh angle. By mounting a fine stainless steel gauze in plastic rings, the thermal inertia is greatly reduced. The gauze therefore rapidly equilibrates in temperature with passing air and condensation is minimal.
