Chilled Mirror Hygrometer
Measures Dew Points Above Ambient Temperature
The MBW CALIBRATION™ MODEL 573™ Dew Point Chilled Mirror Analyzer is a high performance 19″ rack format instrument that is very well suited to fixed industrial installations. The 573 is equipped with an integral measurement head, pressure sensor, sample pump and flow meter for continuous precision monitoring of frost/dew point and absolute humidity values across a wide range of applications. The 573 is very similar in specification to the 973 but adds the capability to measure dew points above the ambient temperature thanks to versions with heated measuring heads and sampling tubes. A special option on the 573H and 573HX variants is an automated steam trap that provides user-controlled draining of condensation collected during operation at dew points up to 95˚C.

WHEN YOU NEED CLIMATIC CHAMBER VALIDATION
Climatic chambers are in widespread use across many industries. They are used to simulate climatic conditions including temperature, humidity, pressure, vibration and light intensity. Conditions are controlled or varied according to user or test specifications. Products and samples are placed within the controlled environment according to defined test specifications that require certain conditions to be maintained. Examples include 40 °C / 75 %rh for drug stability and 85 °C / 85 %rh for electronic component testing. Confirmation that the correct environmental conditions have been achieved is a pre-requisite for compliance with the respective standards that apply in each industry.

Heated Hoses
When measuring dew point above ambient temperature, condensation will form in sample lines where the tube/hose temperature is below the dew point temperature. Heated sample hoses solve this problem by maintaining the tube temperature at a higher temperature. MBW supply heated sample hoses in a range of lengths and fittings to suit most applications.
The heated hose only provides sample path heating upto the inlet connection of the instrument. To avoid condensation inside the instrument, its internal sample path and measuring head must also be heated.
