TSI Velocicheck Air Velocity Meter Models 8330 and 8340
The VelociCheck air velocity meter provides a reliable, accurate and easy way to make air velocity measurements in such applications as HVAC duct balancing, fume hood face velocity testing and others. The meter is pocket-sized and requires no training to operate; just pick it up and start taking readings. Model 8330 has a 37-inch telescoping probe. Model 8340 is intrinsically safe.

TSI 8340 Velocicheck IS Air Velocity Meter
The VelociCheck air velocity meter provides a reliable, accurate and easy way to make air velocity measurements in such applications as HVAC duct balancing, fume hood face velocity testing and others. The meter is pocket-sized and requires no training to operate; just pick it up and start taking readings. Model 8340 is intrinsically safe.

TSI Velocicalc Plus Model 8386
Talk about feature packed -- this little instrument is jammed. The VelociCalc Plus simultaneously measures and logs velocity, temperature, static pressure, Pitot tube readings and humidity, and calculates volumetric flow rate, dew point, wet bulb temperature and heat flow. Multiple sensors but one easy-to-use forty-inch telescoping probe. The rental unit comes with custom software.

TSI AccuBalance Air Capture System Model 8371
Measure the air volume flowing through registers, diffusers and grilles with an AccuBalance air capture hood. Use it to balance an HVAC system, spot check a room or a building or as part of an indoor air quality study. Weighing just seven and a half pounds, the AccuBalance is easy to carry, lift and use. Just hold the hood up to a diffuser or grill and read direct airflow on the large digital display, which is backlit for easy reading in poor lighting conditions. Input temperature and barometric pressure and obtain an automatic conversion between actual and standard flows. The rental unit comes with five separate hood sizes. Accubalance is a registered trademark of TSI Incorporated.

Testo 175 and 177 Series Temperature Monitors
The Testo 175 series consists of 6 compact data loggers, small insize, which measure temperature, humidity, voltage and current. The Testo 177 series consists of 5 instruments suitable for a wide range of applications, ideal for long-term applications. All the loggers which have a display can immediately provide a quick overview of the current reading, the last value saved, maximum and minimum value and the number of times the limit has been exceeded. The Testo 580 data collector, suitable for all the data loggers, and the flexible Testo 575 fast printer opens up a whole new range of possibilities for dealing with measurement data.

TSI 8324 Velocicalc
The TSI 8324 velocicalc rotating vane anemometers accuately measure air felocity and temperature, calculate flow rate, perform averaging, and determine minimum and maximum readings. It also provides data logging capability.

TSI 8592 Air Vel Probe
The TSI's Air Velocity Probe Model 8592 is designed to work with the popular Q-Trak Plus IAQ Monitor. Simply plug it into the accessory poart and you are ready to go. Now you can measure air velocity in real-time, record fume hood face velocty and quickly display calculated volumetric flowrate, all with the same instrument. The velocity measurements can also be stored and downloaded to your computer using TRAKPRO Data Anaylysis Software.

CS DP300 Temperature Dewpoint Instrument
Keeping a specific dew point is requirement for a trouble free plant operation. The mobile dew point measuring instrument DP300 is the ideal service instrument in a handy case. It measures relative humidity, temperature and the dew point up to 15 bars, easy, fast without annoying cable. In general humidity can be measured in all non corrosive active gases. With the pc software the measured data can be recorded in an Excel file and further parameters can be selected: ppm, g/m³, mg/m³, g/kg, atmospheric dew point. Special version up to 350 bars.

TSI 9555 VELOCICALC Multi-function Ventilation Meter
The Series 9555 are portable, hand held, Multi-Function Ventilation Test Instruments. These instruments are available with or without a differential pressure sensor and are designed to work with wide range of plug-in probes. The probes allow users to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. They are designed to measure air velocity, temperature, humidity, CO and CO2. Calculations include air flow, heat flow, turbulence, wet bulb and dew point temperature.

Testo 175 H2 Humidity & Temperature Datalogger
Lightweight and compact, the Testo 175 H2 is an ideal rental solution to accurate humidity and temperature monitoring in the workplace. With its internal sensors and tough ABS construction, as well as the ability to store up to 16,000 readings, the Testo 175 H2 can reliably monitor in a wide range of applications. These include: offices, museums, computer rooms, warehouses, cold storage facilities, industrial greenhouses and manufacturing premises.

Minneapolis Blower Door Building Airtightness Testing System
This system is used to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems, estimate natural infiltration rates, estimate efficiency losses from building air leakage, and certify construction integrity.
