AccuBalance® Air Capture Hood 8380 offers durable, trouble-free operation, this lightweight, ergonomically designed capture hood kit saves time and money by combining multiple measurement tools into one package.
The DP-Calc™ Micromanometer 8715 is one of the most advanced, versatile, and easy-to-use micromanometers on the market today. The 8715 features an auto-zeroing pressure sensor that increases measurement resolution and accuracy along with an intuitive menu structure for ease of operation.
The VelociCalc® Multi-Function Ventilation Meter 9565 features a menu-driven user interface for easy operation in your local language. On-screen prompts and step-by-step instructions guide the user through instrument setup, operation and field calibration.
The 9600 VelociCalc is a portable, handheld Multi-Function Ventilation and IAQ test instrument featuring a menu-driven user interface for easy operation. The high-resolution color screen displays multiple measurements simultaneously in real-time with on-screen prompts to guide you through instrument setup and operation.
The VelociCalc® Air Velocity Meter 9515 is the economical choice for a digital air velocity meter, without compromising accuracy or precision. Professionals find it an ideal tool for face velocity measurements in fume hoods, spray booths, or for ventilation system checks
VelociCalc 5725 accurately measures air velocity and temperature, calculates flow rate, performs averaging, and can determine minimum and maximum readings. Using sweep mode you can quickly provide one averaged reading of velocity or volume over a large measurement area. The large vane head automatically averages velocity and volume readings. 
The AirPro® Micromanometer AP800 is a rugged, compact, configurable and high performing component of the AirPro Solutions platform. It is used in conjunction with AirPro® Mobile Application Software and user-defined feature sets.
The AirPro® Velocity Meter AP500 is a rugged, compact, configurable and high performing component of the AirPro® Solutions platform. It is used in conjunction with AirPro® Mobile Application Software, plug- and- play measurement probes and user-defined feature sets.
Ideal applications for our low flow air velocity transducers include comfort and draft studies, critical environment installations (e.g., clean rooms and hospitals), diffuser design analysis, monitoring drying processes, and air flow monitoring in tunnels and subways. Additionally, they are used as a standard in wind tunnels and calibration facilities, environmental monitoring in greenhouses, and IAQ applications, as well as general engineering applications.
The DustTrak™ II Aerosol Monitor provides real-time aerosol mass readings with gravimetric sampling. For use in occupational hygiene, indoor air quality, outdoor environmental, emissions, remote monitoring and process monitoring.
The SidePak™ AM520i is IECEx, ATEX, CSA, and IECEx-SIM certified for use in explosive environments. It provides real-time aerosol mass concentration readings for PM10, respirable, China respirable, PM2.5, PM1 and 0.8 DPM.
TSI’s 5000 Series Flow Meter combines bi-directional flow sensing with multiple integrated measurements, and operation is easy with its color touchscreen display and FLO-SightTM PC Software.
The TSI 4000 Series inline flow meters were designed for ultra-low pressure loss to minimize flow circuit back pressure and its impact on the system. The meters include digital and analog outputs for flow rate, absolute pressure, and temperature. Volume measurements can be made through the RS232 digital interface. TSI flow meters incorporate a proprietary platinum film sensor designed for measuring gas flows. This enables their use in applications that demand fast response and high accuracy over a wide flow range.
