The accuracy refers to the precision at 25 ℃. When the temperature deviates from the calibration temperature, an additional error of ± 0.36%/℃ is required
The accuracy refers to the precision at 25 ℃, and an additional error of ± 0.05% RH/℃ needs to be added when the temperature changes.

Indoor air quality meter

Model: 7515/7525/7535/7545

IAQ-Calc from TSI in the United States^TMTesters are excellent instruments used for indoor air quality research and monitoring. The TSI7515 indoor quality tester from the United States is used to test CO₂Low priced instruments. TSI7535 in the United States has added automatic storage of CO₂Data functionality. TSI7525 and TSI7545 from the United States can measure and store multiple parameters simultaneously. TSI7525 in the United States can measure CO₂Temperature, humidity, and calculate dew point temperature, wet bulb temperature, and relative humidity of outdoor air. TSI7545 in the United States can also measure CO.

Features and advantages (all models)

● Low drift NDIR CO that can be stably and accurately measured₂sensor

● The sampling function can record multi-point measurement data

● Ergonomic exterior design

7525 And 7545 type

Temperature and relative humidity measurements help determine thermal comfort

Through CO₂ Or calculate the percentage of outdoor air based on temperature

Directly calculate dew point temperature and wet bulb temperature
