DR-4 Resistance Test Instrument for 300ml Workstation

Designed specifically for the performance testing of electronic cigarette resistance to suction and atomizer cartridges, this machine achieves a measurement accuracy of ±0.05kPa within the range of 1–20kPa through 4-position synchronous testing and high-precision micro-pressure sensing. It addresses the pain points of low efficiency and large manual reading errors in traditional single-position testing. With 4 positions working simultaneously, the hourly detection capacity is ≥240 pieces, and the data consistency is ±0.03kPa. It is the "core equipment for suction resistance testing" for electronic cigarette production line quality control, R&D testing, and third-party testing institutions.

Instrument parameters

Core Technology Highlights and Functional Design

✅ 4-Station Parallel Inspection: Efficiency Increased by 4 Times, Adaptable to Production Line Rhythms

✦ Independent Station Design:

4 inspection modules can work simultaneously or independently (one-click mode switching);

The inspection time for a single station is ≤15 seconds (including clamping - testing - data upload), and the efficiency of 4 stations working simultaneously is 300% higher than that of a single station.

✦ Quick-Change Fixture System:

Magnetic fixture can be switched in 3 seconds, suitable for cigarette tubes with diameters ranging from 5 to 25mm (round tubes/irregular shapes);

Self-calibrating positioning slots (±0.02mm repeatability accuracy), eliminating measurement errors caused by clamping deviations. 

✅ High-precision micro-pressure sensing: Millimeter-level control, reliable and traceable data

✦ Core measurement system:

Imported MEMS micro-pressure sensor (range 1–20kPa, resolution 0.01kPa);

Dynamic compensation algorithm: Automatically corrects environmental pressure fluctuations (within ±0.5kPa).

✦ Data-based verification:

Measured deviation of standard part suction resistance ≤±0.05kPa (traditional manual handheld gauge is ±0.2kPa);

Continuous detection 50 times, data consistency deviation <0.03kPa (manual is ±0.1kPa). 

✅ Smart touch interaction: Minimal operation, full data recording

✦ 7-inch industrial touch screen:

One-click access to detection modes (standard mode / custom mode);

Simultaneous display of real-time pressure curve, 4-station detection values, and pass/fail determination results.

✦ Data management function:

Store 50,000 sets of detection records (time / sample number / draw resistance value);

Support USB export of Excel reports (compliant with ISO 17025 laboratory certification requirements). 

Application scenarios and customer value

✅ Full inspection on production lines: Dual guarantee of efficiency and quality

✦ Compatible with high-speed production lines:

Matched with the rhythm of oil injection machines and capping machines (single-piece detection time < 15 seconds);

Full inspection coverage on production lines increased from 30% (manual spot checks) to 100%, with a defective product interception rate of ≥ 99.5%. 

✅ R&D Testing: Precise Quantitative Design Verification

✦ Resistance Characteristics Analysis:

Simultaneously test 4 groups of differently structured cartridges (such as different airway diameters, cotton core densities);

Output pressure-time curves to assist in optimizing the balance between resistance and taste. 

✅ Third-party testing: Authoritative and traceable data

✦ Laboratory certification support:

Compliant with ISO 8243 (e-cigarette testing methods) and GB 41700 (national standard for e-cigarettes) testing requirements;

Test reports can be directly used for product compliance applications (such as EU TPD, US PMTA). 

Reliability and Maintenance

✅ Structural Durability:

✦ The fixture is made of POM wear-resistant plastic (with a lifespan of ≥ 100,000 insertions and withdrawals);

✦ The sensor has an IP65 protection rating (resistant to oil mist and dust). 

✅ Easy-to-maintain design:

✦ Quick disassembly of sensor module (no tools required);

✦ Annual calibration takes only 30 minutes (standard calibration parts provided) 

✅ Operating Procedure (5 Steps for Immediate Learning and Application)

✦ Fixture Installation → Select the magnetic fixture based on the specifications of the e-cigarette cartridge and insert it into the workstation in 3 seconds;

✦ Equipment Calibration → Start the automatic calibration program (with an internal standard leak hole) to ensure accuracy;

✦ Sample Placement → Insert the e-cigarette cartridge into the fixture's positioning slot and gently press to fix it (to prevent falling off);

✦ Start Testing → Click the "Start" button, and the 4 workstations will simultaneously complete the resistance measurement within 15 seconds;

✦ Data Processing → Qualified samples will be automatically marked in green, and unqualified ones will trigger an alarm in red. Data will be automatically stored.
