Pollutracker TR8+ Capabilities

Pollutracker TR8+ Capabilities

The Scentroid Pollutracker includes a sampling pump with adjustable sampling rate, up to 10 chemical sensors that are specified at the time of ordering, and Scentroid’s Pollutracker Application that can be loaded to any customer supplied Android phone/tablet. For each sample location, Scentroid instantaneously records:

  • The concentration of up to 10 chemical vapours in ppm or ppb depending on sensors ordered (See table below for sensor ID’s detail that can be selected in any combination of two at time of ordering. Note that DR8-P1 and DR8-P2 Total VOCs – PID sensors can be specified at a nominal additional charge at the time of ordering )
  • Measure Temperature and Humidity
  • Record GPS position of each measurement
  • Measure directly from ambient air
  • Can record continuously for remote monitoring via

Will the sensors be affected by temperature?

There is temperature compensation circuitry and software built into Pollutracker for compensation up to 50C.

How long will the sensors last?

Sensors will last 2 years.


What our clients says about Odotracker

I use the Pollutracker in chemical plant to determine emission points and monitor air pollution and green house gases. It is extremely sensitive and reacts quickly to gases.
