How Testo Instruments Have CO2 Monitoring Sorted

How Testo Instruments Have CO2 Monitoring Sorted

The world has woken up – too much CO2 is bad for the planet, and poor indoor air quality is detrimental to people's health and well-being.

CO2 meters are the first line of defence in identifying elevated interior CO2 levels. They pave the way for the essential steps to improve air quality in offices, classrooms, production sites, or any indoor space.

This article spotlights four outstanding and representative commercial models offered by Testo Instruments – a world-leading manufacturer of CO2 meters.

Why Testo?

Testo is a recognised leader in designing and manufacturing an extensive range of portable test and measurement instrumentation and solutions. Testo has over 60 years of measuring and engineering experience and is renowned for providing exceptional value and first-class scientific devices.

CO2 Basics - What is It?

Carbon Dioxide is abundant in the atmosphere, and all aerobic organisms produce carbon dioxide through respiration from tiny bacteria to our pets and us. CO2 can be found in concentrations as little as 380 parts per million (ppm) in less populated outdoor locations.  In cityscapes and urban areas, ambient outdoor levels are usually higher.

Why Measure CO2 Indoors?

Indoor carbon dioxide concentrations are directly related to ventilation adequacy and occupant density. Heating, ventilation and air conditioning systems (HVAC) balance re-circulating a large portion of the indoor air - to maintain comfort and control energy costs - while drawing in some fresh air.

The problem is that it’s virtually impossible to determine air quality by simply being in a room and breathing. Yet, indoor air quality can have a profound influence on people's health and well-being. When air exchange is inadequate compared to a room’s occupant density, CO2 concentrations can climb rapidly. CO2 concentrations above 1000ppm result in drowsiness, headaches and loss of attention. 

CO2 Monitoring Solutions by Testo

Testo offers a spectrum of CO2 monitoring devices that collect and provide information in various ways. We have summarised four types of modern, efficient and cost-effective Testo CO2 monitoring solutions you can find at Instrument Choice.

Mobile Comprehensive Evaluation of Indoor Air Quality:

Testo 440 CO2 Kit with Bluetooth
Product code: IC-0563-4405

In a nutshell: Use this practical and portable kit to measure CO2 concentration, humidity and air temperature and evaluate overall indoor air quality. The multifunction measuring instrument is straightforward to navigate and is convenient for your indoor air quality measuring tasks.

How it works: The Bluetooth sensor collects indoor air quality information and wirelessly relays it to the Testo 440 air velocity and IAQ measuring instrument.  On the handheld unit, you can quickly evaluate and store measured data. The Testo 440 includes a measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer.

Great for:

  • Offices
  • Schools
  • Production areas; and
  • Storage facilities.

 Specifications:

CO2 Range: 0 to 10000ppm

CO2 Accuracy:

  • 0 to 5000 ppm ±(50 ppm + 3 % of mv),
  • 5001 to 10000 ppm ± (100 ppm + 5 % of mv)

Also Measures: humidity and air temperature and calculate dew point, wet bulb temperature and absolute humidity

Norm-compliant Recordings of Comfort and CO2 Concentrations:

Testo 400 IAQ and comfort kit with tripod
Product code: IC-0563-0401

In a nutshell: Ideal kit for IAQ professionals, focusing on indoor air quality and comfort level. The package includes the Testo 400 universal IAQ measuring instrument, a Bluetooth carbon dioxide probe, a turbulence probe and a globe thermometer.

How it works: The Bluetooth sensor collects CO2 data wirelessly while the additional wired probes collect additional air quality information. The highly accurate data is available instantly on the practical handheld display. Thanks to the integrated WLAN and Bluetooth interfaces, you can document measuring values directly on the customer's site and send them by email or analyse them using the Testo DataControl PC software.

Great for:

  • HVAC professionals.

Specifications:

CO2 Range: 0 to 10000ppm

CO2 Accuracy:

  • ±(50 ppm + 3 % of mv) (0 to 5000 ppm)
  • ±(100 ppm + 5 % of mv) (5001 to 10000 ppm)

Also Measures: Temperature, Pressure, Velocity, and Globe temperature.
