Filter membrane automatic weighing system

HW-9900 is a product independently developed and produced by Shandong Hanwen Instrument Co., LtdFilter membrane automatic weighing systemUsed for fully automatic balancing and weighing of sampling filters, filter heads, and filter cartridges in low concentration particulate matter. The weighing system adopts an upper and lower split design, with 6 sets of universal Fuma wheels at the bottom for easy movement and fixation. Equipped with professional industrial control computers and workstations, it can automatically read balance data, record well generated tables, and print with one click; Equipped with a fully automatic robotic arm and composite sample coating, it can automatically retrieve samples, with 40 filter membranes, 40 filter heads, and 20 filter cartridges pre weighed at 47mm or 90mm each time; Equipped with a filter membrane coding recognition system to ensure that each sample information can be recorded and tracked.

Execution standard:

HJ836-2017 Determination of Low Concentration Particulate Matter in Fixed Source Exhaust Gas by Weight Method

GB/3095 Environmental Air Quality Standards

HJ 618 Determination of PM10 and PM2.5 in ambient air by weight method

HJ 656 Technical Specification for Manual Monitoring Method (Weight Method) of Environmental Air Particulate Matter (PM2.5)

JJG/1036 Verification Regulations for Electronic Balance

Technical advantages:

1. The seismic performance of *

Adopting five level seismic measures, even when tapping the outer wall of the box during startup, the last digit of the one hundred thousandth scale will not jump randomly.

2. The Application of Tai Chi Style

Adopting a dual upper and lower air duct design, the two air ducts work in a cyclic manner, which can quickly maintain the temperature and humidity inside the box without affecting the balance.

3. High precision sensing detector

The temperature control accuracy is 25 ℃± 0.2 ℃, and the humidity control accuracy is 50% ± 2% R.H.

4. Exclusive Workstation

After weighing each sample, the balance data is automatically read, a record table is automatically generated, and one click printing is done;

It can read the raw data of any historical node, ensuring that the data can be recorded and traced, making it easier to cope with flight inspections.

5. Fully automatic robotic arm

Equipped with a fully automatic robotic arm, it can automatically pick up and weigh samples, effectively freeing up manpower.

6. Membrane coding recognition system

Equipped with a QR code/barcode recognizer, it can record sample information throughout the process.

7. Rotary Sample Tower

Equipped with a rotary sample tower, it can simultaneously pre load the constant weight filter membrane, filter head, and filter cartridge, making it easier to access and occupying less space.

8. * Chiller

Independently developed * chiller, with a working noise of less than 30 decibels, can reach the set temperature within 15 minutes and achieve IP65 waterproof level.
