A programmable CO2 detector and controller that is ideal for HVAC applications in schools, offices and other indoor workplaces.
The ESTSP measures CO2 and temperature with a relay control output or linear 0-10V/4..20mA to control ventilation units and variable speed drives.
The ESTSP is very easy to use and maintain. The ESTSP has an ABC style self-calibration with the ability to zero, or reset itself, for optimal accuracy. Therefore, the ESTSP can run for many years without extensive support or re-calibration. Alternatively, the team at Edaphic Scientific can re-calibrate the ESTSP for you, if required.
The Tongdy ES-TSP model is similar to the SenseAir tSense model and performs many of the same functions. The ES-TSP is a lower cost version of the tSense model and is ideal for many indoor air applications.
