15-23: Wet Bulb Measurement with Psychrometers and Hygrometers Field Test Iron Rot Attack

15-23: Wet Bulb Measurement with Psychrometers and Hygrometers Field Test Iron Rot AttackWorldwide, the air moisture content entering a cooling tower may be measured either with a relative humidity sensor, a psychrometer, or a capacity hygrometer. Some European standards, dedicated to cooling tower thermal tests such as EN 14705, historically recommend hygrometers for cooling tower acceptance tests for more than 20 years now, while the CTI ATC 105 (and also 140 ; 150) standard only recommends the use of mechanically aspired psychrometers.

and areas of the towers that experience the most advanced degree of degradation

Over the past 50 years or so

It is usually recognized that a Cooling Tower System needs water treatments and a maintenance program to prevent the transmission of Legionnaires Disease

and 3) methods for preventing or correcting these problems

Environmental restrictions and the need for water conservation have led to the development of a new
