accurate results, it should be easy to check its calibration. Importantly, the HSA advises that CO2 levels should be monitored throughout the day, and the HSE similarly notes that instantaneous (snapshot) readings can be misleading. It could be the case, for example, that the reading is taken at a time when someone has left a door open that is normally kept closed, which could lead to a misleadingly low measurement. It is far more satisfactory to take multiple readings over a day or an even longer period of time. This can be done manually, of course, by checking the monitor at predetermined intervals and noting the readings, but this is tedious, and it is almost inevitable that someone will very soon forget to take a reading – or, indeed, several readings. A better approach is to use a CO2 monitor with logging facilities that automatically takes readings at user-defined intervals and stores them in internal memory so that they can be downloaded later for checking. An example of a cost-effective and easy-to-use monitor that meets all these requirements is the CA 1510 from Chauvin Arnoux, which can store up to one million readings internally
for subsequent download via a USB connection or via a wireless Bluetooth link. The CA 1510 is a good solution for initial surveying of locations using the MAX/MIN function to inform the Covid-19 risk assessment and then as fixed monitors as a long-term control measure. Accessories for this versatile instrument include a calibration kit and mounting brackets to facilitate semi- permanent or permanent installation, should this be required. While helping to safeguard employees and the public against Covid-19 is, for most people, likely to be a more than adequate reason for investing in a CO2 monitor, it is also worth noting that even after the pandemic has subsided – as we all hope and believe it will – a good monitor will continue to earn its keep. The best types, including the CA 1510, also monitor temperature and humidity, so they provide an excellent way of assessing the overall quality of the environment. This matters because numerous studies have shown that a poor working environment not only makes people feel uncomfortable but also greatly reduces their productivity – which is a concern for every type of organisation whether it be a commercial business, a school or even a hospital.
Carbon dioxide monitors with data logging facilities are readily available at modest cost. They are dependable, easy to use and can be a very useful tool in the helping to safeguard building occupants against the risk of Covid-19 infection. At present, they represent a very small investment for a very significant benefit. Further, as we have already mentioned, they will have continuing value even when the immediate threat of Covid-19 has passed. So, if you haven’t already invested in this valuable safeguard, now must surely be the right time to do so.
