The heat stress monitors of the QUESTemp series allow you to measure and analyze the exposure levels related to the heat stress that exists in a given environment. They perform the calculation of the TGBH index value. The use of an air probe (additional accessory) allows the calculation of the PMV and PPD thermal comfort indices. They have advanced functions for generating reports, downloading the data through a PC. Some models are certified for intrinsic safety.

Sound Sound Series 3M Pro SE / DL

The EVM series monitor is a compact device, easy to use, with the ability to simultaneously monitor in real time, various parameters of air quality and particles. Depending on the configuration, the following can be quantified: Particle mass concentration (PM2.5, PM10, PM4 or TSP), temperature, relative humidity, CO2, toxic gases, volatile organic compounds and air speed (optional).
The three monitor configuration options are:
EVM-7 Air and Particulate Monitor
- Simultaneous measurement of gas and particle concentrations in real time.
- A 25 or 37mm cassette filter allows sample capture for later laboratory analysis
With external temperature and relative humidity sensor - CO2 sensor, PID and a toxic gas (CO, H2S, NO2, SO2, HCN among others).
EVM-3 Particle Monitor
Special for direct readings in real time of the concentration of particles.
It measures simultaneously: Particles (mass concentration PM2.5, PM10, PM4 or TSP), temperature and relative humidity.
