testo 435-2 Multifunctional measuring instrument for measuring HVAC systems and indoor air quality, with readout storage,PC software and USB data transmission line, including battery and factory report
Product Introduction:
This multifunctional measuring instrument is suitable for measuring ambient air conditions, assessing indoor air quality and checking air conditioning and ventilation systems
高效的测量处理使得它非常的出众.探头控制菜单和用户选择界面,例如,在管道测量或长期测量中,确保用户能简便的进行操作.室内空气质量探头可以通过测量CO2浓度,空气湿度和空气温度来判断室内空气质量.
In addition, the instrument can be connected to the illumination probe and comfort probe for air flow assessment, clear analysis and archiving function, ensure PC archiving processing. Measurements of air temperature, humidity and wind speed can be made simultaneously in the new thermal probe. In addition, it can also be external temperature and humidity probe. The disy disys readings from up to three temperature sensors. The instrument can print reports on the spot through testo Express printer
Advantages at a glance:
The instrument can store up to 10,000 readings
