Function introduction: Environmental Monitoring

Model: yh-2-9

Parameters: 

1. Temperature overrun setting function. The normal temperature range is 14 ℃ - 24 ℃, which can be adjusted according to the user's environmental needs. When the temperature is lower than the set value, the alarm is higher than the set value, and the normal range is cancelled;

2. Humidity over limit setting function, the normal temperature range is 45-60rh%, which can be adjusted according to the user's environmental needs. The humidity is lower than the set value alarm, higher than the set value alarm, and the normal range is cancelled;

3. Dust overrun setting function, normal range ≤ 75mg / M 3， It can be adjusted according to the user's environmental needs. If it is higher than the set value, the alarm will be given and the normal range will be cancelled;

4. Anti corrosion overrun setting function, normal range ≤ 0.01ug/m 3， It can be adjusted according to the user's environmental needs. If it is higher than the set value, the alarm will be given and the normal range will be cancelled;
