Get back to school safely with Testo’s classroom monitoring solutions.
California Assembly Bill (AB) 841,372 mandates CO2 monitoring and data logging in classrooms – Testo 160 is perfect solution for the data logging that allows you to return and remain in the classroom.
- Safety measures in ventilation are needed to mitigate the impact of viruses (COVID 19 and others) and virus spreading. California and Federal guidance have been issued to help address the problem by monitoring classroom air.
- California has funds to administer programs for K-12 schools.
- Federal Funding is well over $170 billion.
- Testo has the right monitoring instrument, at the right time, to get you safely back into your classrooms.

Virus spread and its relationship to CO2 and Relative Humidity -
The indoor air quality (IAQ) parameters the testo 160 IAQ measures and logs
- CO2 levels used as indicator for risk within indoor spaces.
- CO2 has relatively similar behavior (buoyancy) as some viruses and can therefore be used as a surrogate for monitoring.
- Concentrations of CO2 above certain levels (800 or 1000 ppm depending upon circumstances) indicated insufficient ventilation (or“clean” air exchange) and can potentially increases transmission rate.
- CO2 has a pivotal role in student attention and learning.
- Studies have indicated concentrations below 800 ppm can significantly increase student attention and cognition.
- Increasing ventilation rates can lower absentee due to illness by 10 to 17%.
- Annual attendance of students is reduced by .02 % for every 100 ppm increase in CO2 measured.
Studies regarding Relative humidity (Rh)
- Relative Humidity (Rh) is shown to have significant impact on the time a virus remains aloft in rooms and on its survivability.
- The optimum levels for lowest viral transmission is between 40 and 60% relative humidity. Exceeding these boundaries can lead to detrimental impact as shown below.
- Droplets stay airborne longer (in still air from 5 seconds to 41 hours).
- Droplets travel deep into lungs.
- Dry air impairs the fluid in lungs and the body's ability to clearing.
- Larger diameter (COVID or others) droplets fall faster.
- Viable longer on surfaces (hours to several days).
- Other problems - Mold growth with increased moisture.
