RBM-4D Bioaerosol Monitor
Product Description
The RBM-4D real-time bioaerosol monitor enables real-time detection of microbial concentrations in the air. When the concentration of bioaerosol particles in the air is higher than the preset value, the instrument will automatically warn. The instrument has the advantages of high sensitivity, fast response and easy to use.

The RBM-4D real-time bioaerosol monitor enables real-time detection of microbial concentrations in the air. When the concentration of bioaerosol particles in the air is higher than the preset value, the instrument will automatically warn. The instrument has the advantages of high sensitivity, fast response and easy to use.
1. Automatic Monitoring: After startup, the device automatically detects the concentration of microorganisms in the air, making it easy to control and operate. Supports unattended operation: the instrument can run continuously for long periods without the need for consumables.
2. Excellent Real-Time Performance: Enables on-site real-time detection, with an early-warning response time of less than 20 seconds.
3. High Sensitivity: Minimum detection limit is no more than 50 microbial particles per liter.
4. High Accuracy & Low Omission Rate: Based on the principle of laser-induced intrinsic fluorescence detection, it can detect nearly all microbial particles, including non-cultivable microorganisms. Low False Alarm Rate: A specific algorithm excludes interference from pseudo-biological particles, effectively reducing false alarms.
