Humidity control is critical in many spaces where flammable or explosive materials such as fuels, chemicals, explosives are being stored. These spaces are designated as hazardous due to potentially explosive atmospheres. They require specially designed and approved instruments for safe operation.
Vaisala offers a family of intrinsically safe humidity instruments for hazardous locations. These instruments must be properly installed with appropriate safety barriers or isolators. Always refer to the User's Manual for complete information regarding the installation and wiring of intrinsically safe instruments.
