The Fully Air-Conditioned 19" Container Solution

A Small But Powerful Container For Your 19" Rack Instruments

The 199 is a stand-alone air-conditioned environmental weather protection housing for 19" rack instruments, such as the Environmental Dust Monitor EDM 180+, the Scanning Mobility Particle Sizer 5420, or the Condensation Particle Counter 5421. The 199 is transportable thus making stationary measurements at different locations feasible.

The 199 is suitable for all weather conditions from tropical heat to arctic cold. All you need is a mains supply and less than 1 m2 of space. This configuration sets the 199 into a worldwide leading position of environmental monitoring for temporary field campaigns, continuous monitoring or scientific projects. Careful design according to customer´s needs and utmost precise manufacturing, using welding robots and fully automatic powdercoating production lines, result in an outstanding quality for each housing.

The digitally controlled air-conditioning reliably maintains the target temperature for ambient temperatures between -20°C and +60°C and a solar incident radiation of up to 3 kW/h/m² (which corresponds to e.g. the Californian desert in summer). The target temperature is set on an easy-to-use digital display with up and down buttons.
