Aerosol-Neutralizers
Aerosol neutralizers are an essential piece of many aerosol research studies because aerosol particles dispersed by nebulization, combustion, or powder dispersion are usually electrostatically charged.
Normally, a high level of electrical charge is undesirable because it increases the particle loss to the walls of transport and sampling systems, or it can affect filter-efficiency measurements.
To ensure that instruments operating on the electrical mobility principle work properly, aerosol particles entering these instruments require an aerosol neutralizer to impart a predictable charge distribution to the aerosol particles.
Neutralizers can be separated into two categories based on how they charge the particles. One group is the radioactive neutralizers, which use the emission of alpha (positive) or beta (negative) particles from decaying radioactive elements to impart charge to the particles. The other group is the non-radioactive neutralizers, which use electricity to generate x-rays or produce high voltages that can charge the particles directly.

Liquid Flow Controller
Built upon field proven technology, the Turbo™ Liquid Flow Controller (LFC) 2950 was engineered to pair with MSP Turbo II™ Vaporizers to provide a reliable, high-performance liquid vapor delivery solution for semiconductor thin film deposition processes (including CVD, PECVD, ALD, and MOCVD). The diagram below shows how the LFC fits into the liquid vaporization system MSP offers.
The MSP Turbo™ Liquid Flow Controller provides ultra-fast response time − able to reach ±1% of set point within 300 ms, saving time and money by increasing throughput and reducing waste. Our new LFC also offers best-in-class accuracy, repeatability, and stability − delivering the high precision performance needed for 300 mm microelectronic processes. High accuracy, excellent repeatability and exception stability can reduce chamber/tool variation, allowing more tightly controlled processes leading to better yield.

Heat Stress Monitors
Heat stress management is often viewed as time-consuming and complex. Simplify your heat stress management with TSI’s intuitive QUESTemp° Series Heat Stress Monitors.
QUESTemp° Heat Stress Monitors are designed to quickly and accurately evaluate potential heat stress environments. These instruments deliver high-performance monitoring using Wet Bulb Globe Temperature (WBGT) sensing technology, the standard for heat stress management, and the calculation of a WBGT Index value.
Our monitors allow you to eliminate daily maintenance. Convenient stay time parameters per multiple standards help determine work-rest ratios, and IP 54 ingress rating helps protect units from exposure to dirt, dust, oil and water.
Our monitors are designed to withstand the rigors of everyday use in demanding environments, providing reliable monitoring throughout the life of the product.

Laboratory Monitors & Controls
Ventilation demands, driven by fume hood exhaust flows and air change rates, means laboratories can use six times the energy of a similarly-sized office building. Operating one fume hood uses as much energy over the course of a year as three homes!
