In today's rapidly rising awareness of environmental protection, professionals engaged in indoor air quality monitoring deeply understand the most important issue, which is how to effectively monitor indoor environmental parameters to ensure a good indoor working environment.

accurate measurement
TSI's Q-TrakTM indoor air quality monitor can measure multiple critical parameters by connecting probes with different functions
CO2、CO、 Temperature, relative humidity, wind speed, and VOC. There are four VOC probes to choose from, which can measure low concentrations (ppb) or high concentrations (ppm). When the molecular weight and response coefficient of a specific VOC are input, its mass concentration can be calculated

data management
Q-TrakTM has a beautiful design, is lightweight and sturdy, and is easy to carry. It can display readings in real time, as well as monitor and store data for a long time. Advanced data storage mode, which can set parameters such as start/stop time and sampling interval. If data is stored every minute, Q-TrakTM can continuously store data for a whole month. In addition, for the convenience of unattended long-term monitoring, QTrakTM can also use AC power.

Convenient and easy to use
The Chinese operating interface and simple menu operation of Q-TrakTM facilitate instrument setup and on-site calibration work. The TrakProTM data analysis software randomly attached can transmit the monitored data to a computer and perform further analysis on the data. With this software, detailed charts and reports can be created to make the entire monitoring results more communicative. In addition, QTrakTM's keyboard lock function effectively prevents accidental operations from occurring.
