At present, sterilization workshops, laboratories, and operating rooms in industries such as pharmaceuticals, biological products, health products, beverages, and hospitals widely use the colony assay to determine the number of bacteria in the air.
Although this method is simple, it has many drawbacks:
1. Cannot know the number of bacteria contained in a unit volume of air;
2. Due to the slow natural sedimentation of bacteria, it is difficult to collect, with low efficiency and long collection time;
3. The sedimentation of bacteria is affected by airflow, resulting in significant errors.
The JCQ-5 planktonic bacteria sampler overcomes these shortcomings by designing and manufacturing according to China's GMP standards and referencing similar foreign products. Has the following advantages:
1. Chinese and English operating systems;
2. Programmable, sample size can be freely selected from 1 to 6000L;
3. Supports 100-240V AC power supply and independent battery power supply;
4. Sampling flow rate of 100L/min ± 5%;
5. Small size, easy to operate;
6. LED content display for easy viewing of various settings;
7. Parameters such as sampling volume and sampling time can be stored in groups;
8. Dual use AC/DC, rechargeable battery DC14.8V large capacity battery, can work continuously for more than 6 hours after being fully charged.

The FL-1 type air flow meter adopts the principle of pitot tube, which automatically detects the air pressure at multiple points and multiple times, and calculates the air flow automatically. The FL-1 type air volume meter can be directly used to measure the air volume of air vents and pipelines, with fast and simple measurement, and is widely used in industries such as HVAC and purification technology. For the convenience of customers' on-site inspection work, a mobile bracket is specially equipped, which can be raised up to 2.2m, and the overall height can be raised up to 3.2m (including 1m of the air volume meter body). Our factory is the first in China to launch the production of this product based on advanced technology of similar foreign products. Every FL-1 type air flow meter undergoes multi-point air flow calibration using a strict 0.5 level standard wind tunnel calibration device at the factory, providing reliable quality assurance for users to accurately measure air flow.
