Description
FEATURES:
1. Product overview
TR-PS1000 large-flow particle sampler adopts large-flow imported brushless fan, the flow control of the instrument adopts high-precision micro-pressure sensor, and the filter membrane weighing method is used to capture the total suspended particulate matter ( TSP ) in the ambient atmosphere. PM10 or PM2.5 can be collected after the cutter . It can be used for sample collection of particulate matter in the fields of environmental monitoring, labor protection, scientific research institutions, etc.
2. Implementation standards
HJ/T 374-2007 “Technical Requirements and Testing Methods for Total Suspended Particulate Matter Samplers” JJG943-2011 “Total Suspended Particulate Matter Sampler”
3. Technical characteristics
- Electronic flow meter is used to control the sampling flow, with high intelligence, stable flow, stable operation and low noise.
- With single sampling, multiple sampling, sampling every other day, cycle sampling and other sampling methods.
- Using OLED display, the working temperature range is large, no backlighting is required, and it can be applied to various occasions.
- Using DC brushless motor, it can work continuously for a long time.
- Automatically accumulate the sampling volume, and at the same time convert the accumulated standard sampling volume according to the air pressure and temperature measured by itself.
- Automatically save the sampling volume, standard sampling volume and sampling time and other information, and can provide 100 sets of data for users to query.
- If the sampling does not reach the set flow rate of the instrument within a certain period of time, it will automatically shut down for protection.
- Automatically detect the power supply status. During the sampling process, the power failure will automatically save the sampling data. After the power is turned on, the sampling will be automatically resumed and the power failure time will be deducted.
- It has a real-time clock to provide users with the current date and time, which is convenient for users to operate.
- The maintenance menu has a password to ensure data security.
- The TSP/PM10/PM2.5 sampling head is made of aluminum alloy, which has no electrostatic adsorption, light weight, no rust, and is easy to install and carry.
- With RS232 interface, sampling data can be printed through micro-printer or exported through U -disk data, and the instrument can automatically identify the capacity of U -disk.
