This applications note discusses the various methods of verifying sensor accuracy including "bump testing", fresh air calibration and span calibration in order to aid the user in setting up proper calibration frequencies and procedures.
Explains how sample draw kits can fail, and the tests which must be used to verify proper performance before every use of any gas detector sample draw kit.
This application note provides end-users, and detector support personnel, with all of the information required to specify complete gas detection systems for monitoring reactive gases for worker safety and health applications.
This Applications Note is designed to provide information on the best way to set up and operate gas detectors used primarily to monitor combustible solvent and fuel vapors in the lower explosive limit (%LEL) range, and associated volumetric scales 0-1.00%
Explains why carbon monoxide and nitrogen dioxide are associated with ice skating rink activities, and the regulations which may require monitoring for these hazards.
Provides a discussion of the capabilities, limitations and proper use of portable air purification and regulation panels, which are used to provide airline respirator users with Grade-D breathing air.
This application note provides a comprehensive overview of the effects of cold weather on the functionality of a gas detector. Subsections include general operating principles, temperature compensation and sensor accuracy in extremely cold temperatures.
Biosystems currently offers four different sensors for the detection of chlorine and chlorine dioxide. This applications note provides an overview of the differences between the four sensors in order to assist in purchasing decisions.
Biosystems Cannonball3 is available with dual sampling pumps for sampling inert and nearly inert environments. This applications note includes a broad discussion of inert sampling practices and the theory behind the dual pump design.
A broad discussion of toxic gas hazards in confined spaces including both short and long-term risks. Includes an overview of Ceiling, STEL and TWA calculations.
Oxygen, combustible gas and toxic gas alarm settings are discussed in the context of OSHA requirements. Biosystems default alarm settings are also covered.
This applications note begins with a basic discussion of how electrochemical toxic and catalytic hot-bead LEL sensors work, and then moves on to give possible explanations for negative gas readings. It concludes with guidelines on what to do when negative gas readings occur.
