ABSTRACT:
A humidifier for conditioning fluid for delivery to a test chamber, such as an incubator, includes means for automatically regulating the quantity, level and temperature of a body of water through which mixed gases, such as air and CO.sub.2, are bubbled to entrain moisture in the gases. The water is heated to below its boiling point. The relative humidity of the saturated mixture delivered to the test chamber is usually at least 90% at temperatures between about 30.degree. - 60.degree.C.
