The Q 3 provides detection and monitoring of Oxygen (O 2), Combustibles, and toxic gases that include Hydrogen Sulfide (H 2 S), Carbon Monoxide (CO), Sulfur Dioxide (SO 2) and Hydrogen Cyanide (HCN).Q 3 can deliver wireless real-time

Technologies XT-XWHM-Y-NA GasAlertMax XT II

The Technologies XT-XWHM-Y-NA GasAlertMax XT II 4-gas detector with pump is a handheld, four-gas detector that uses an electrochemical cell sensor to monitor ambient H 2 S and carbon monoxide (CO), a capillary pore fuel cell to measure oxygen levels, and a catalytic bead sensor to monitor ambient combustible gases continuously. It has audio, visual, and vibration alarms, which alert

Perfusion - Wikipedia

2019-1-17Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue,[1] usually referring to the delivery of blood to a capillary bed in tissue. Perfusion is measured as the rate at which blood is delivered to tissue,[2] or volume of blood per unit time (blood flow) per unit tissue mass. The SI unit is

Permeation - Wikipedia

2019-1-20In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (such as a liquid, gas, or vapor) through a solid.It is directly related to the concentration gradient of the permeate, a material''s intrinsic permeability, and the materials'' mass diffusivity.Permeation is modeled by equations such as Fick''s laws of diffusion, and can be measured using tools such as

Combined LEL and thermal conductivity module featuring MEMs sensor with on-board measurement range switching. The MP-7217-TC gas sensor has been designed to measure Methane over the explosive concentration range and up to 100% by volume.

Engines and nanoparticles: a review - ScienceDirect

Most of the particle number emitted by engines is in the nanoparticle range, D p <50 nm, while most of the mass is in the accumulation mode, 50 nm <D p <1000 nm, range. Nanoparticles are typically hydrocarbons or sulfate and form by nucleation during dilution and cooling of the exhaust, while accumulation mode particles are mainly carbonaceous soot agglomerates formed directly by combustion.
