Monitor CO2 in Schools with the CDT-S Transmitters!

Series CDT-S Carbon Dioxide and Temperature Transmitter

Dwyer recently released its new -S option for the Series CDT carbon dioxide and temperature transmitters. Built upon Dwyer’s standard carbon dioxide transmitter, the -S option has a front-facing LED that illuminates when the CO2 level exceeds 1,100 PPM. 

This new feature addresses concerns raised by legislation, including California Assembly Bill 841 and Nevada Assembly Bill 257. California’s Assembly Bill 841 was signed into law in 2020, while Nevada’s Assembly Bill 257 was approved in 2021.

Similar to any controlled environment, it is vital to monitor and proactively interpret the pressure, temperature, relative humidity, carbon dioxide (CO2) supplementation, and irrigation of your growing space. Losing control of your environment can lead to cultivation headaches ranging from poor air flow to extreme temperatures; additionally, high humidity and low irrigation rates can lead to the spread of disease and viruses.  Continue reading “Temperature and Relative Humidity in Greenhouses and Cannabis Production”
