  • Description

    Testo 315-3 CO/CO2 Monitor

    The Testo 315-3 CO/CO2 Monitor is a carbon monoxide/dioxide monitor that stands out because of its straightforward operation and capacity to transfer data to a computer or Testo 330 Flue Gas Analyser via infrared or USB. It can simultaneously or directly measure ambient levels of carbon monoxide and carbon dioxide and display those readings on its digital screen. It conforms to British Standard 6173:2009 and EN Standard 50543 whilst the tough sensors are accurate to ±3-5ppm for CO and ±300-500ppm for CO2. A Type K air temperature probe adds further functionality whilst humidity can also be measured between 5 and 95% so air quality is comprehensively assessed. Audible and visual alarms warn the user when the adjustable limits have been exceeded, thus improving safety and making results clearer.

    The 315-3’s 18-hour battery life means it can be easily used around a large site without charging whilst it's durable build quality means it can withstand the grind of daily use. The Testo 315-3 is available with a case and infrared printer depending on the user's requirements. All units come with a two-year warranty and the Testo 315-3 has everything needed to monitor the effect of a fuel-burning device on ambient temperature, humidity, carbon dioxide and carbon monoxide in an enclosed space.
