The average American spends about 90 percent of their time in closed rooms. The room climate often has a considerable effect on our health and overall wellbeing. There’s a big difference if the air - such as in an office - is fresh and invigorating, or if it’s heavy and stale. Stale air can cause fatigue and tiredness, and considerable discomfort. It can also lead to a lack of concentration, and have a detrimental effect on your health. The testo 535 CO₂ meter is designed to measure the CO₂ concentration in the ambient air, because stale air has much higher CO₂ levels than fresh air.

Areas of application and benefits of the testo 535 CO₂ meter

The testo 535 CO₂ meter is ideal for monitoring / optimizing room climate, such as in offices. It can also be used to check if existing AC and ventilation systems provide rooms with enough fresh air.
The high precision, long term stable, 2-channel IR sensor measures the CO₂ concentration in the ambient air. The 2-channel infrared sensor is maintenance free and can be used for long term measurements. The readings from such measurements can be analyzed using min / max and average values, which can be displayed at the touch of a key.
The optional testo turbo printer can provide you with measuring data printouts that include both the time and date, while you are still on site. The optional TopSafe protective cover protects your meter against impact and dirt and water ingress.

Features:

Quick and accurate CO₂ measurements
Long term measurements using max / avg values
Long term stable / maintenance free infrared sensor
Optional testo turbo printer for printouts on site
