Testo Testo 535 二氧化碳检测仪, ±2% + 50 ppm精度

Testo 535 是一个高效的二氧化碳测量仪器，用于测量室内的空气质量。室内空气质量不良可导致疲倦、注意力不集中和疾病，在很多情况下是由于通风不足造成的。二氧化碳被用作室内空气质量评估指标 — 如果室内空气的二氧化碳含量太高（限制值：1000ppm），会感觉空气热闷。

The Testo gas detector is an efficient CO2 measuring instrument for measuring indoor air quality. Bad air quality in rooms can lead to tiredness, lack of concentration and illness and is caused in many cases, by insufficient ventilation. CO2 is used as an indicator when assessing indoor air quality. If the CO2 in indoor air is too high (limit value: 1000ppm), the air feels stuffy and stale.
