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
TSIThe company'sQ-TrakTM The indoor air quality monitor has a multifunctional sensing detection rod that measures multiple critical parameters simultaneously(CO2、CO、Temperature and relative humidity)If equipped with a wind speed probe,Q-TrakTM Becoming a“Five in one”Instruments. In addition,Q-TrakTM It also provides dew point, wet bulb temperature, and outdoor air percentage for ventilation calculations.
data management
Q-TrakTMBeautiful appearance, lightweight and sturdy, easy to carry, can display readings in real time, and can also be used for long-term monitoring and data storage. Advanced data storage mode that can be set to start/Stop time, sampling interval and other parameters. If data is stored every minute,Q-TrakTMCan store data continuously for a whole month. In addition, in order to facilitate long-term monitoring without supervision,Q-TrakTM AC power can also be used.
Convenient and easy to use
Q-TrakTMUtilizing non scattering infrared radiation(NDIR)Sensor measurementCO2Concentration and electrochemistry(EC)Sensor measurementCOConcentration. Both of these sensors can be easily calibrated according to the actual situation on site. Randomly attachedTrakProTMData analysis software 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,Q-TrakTMSpecially provided is an adjustable wristband, making the single handheld instrument more reliable. The keyboard lock function effectively prevents accidental operations from occurring.
