When carrying out measurements with hazardous substances the safety regulations and, if 
available, information in the appropriate safety data sheets must be taken into account when 
handling such substances. 

 SPAC SPAC SPAC SPAC 

 

The controls of the MSA and a connected computer must not be operated when wearing 
protective gloves, which have already been used for handling hazardous materials.

Intended use and application restrictions 

 

The MSA is only intended for measuring the contact angle of liquids on solid surfaces and 
for determining the surface free energy of solids. 

 

The intended use includes the exclusive use of accessories supplied by KRÜSS or substitutes 
with an identical design if disposable accessories are being used. 

 

Do not use the instrument in atmospheres containing dust, smoke or aerosols; these affect 
the optical components of the instrument and could damage them. 

 

The following temperature ranges apply for working with the MSA: 

 

10°C to 40°C for operation 

 

-10°C to 70°C for storage 

 

Avoid contacting the optical components with sharp objects.
