AND Leak Tester AD-1690 thiết bị kiểm tra độ rò rỉ khí micropipette (−20 kPa /2 µL ~ 10,000 µL.)

Leak Tester AD-1690

• Testing Range: Compatible with micropipettes ranging from 2 µL to 10,000 µL.
• Method: Uses vacuum depressurization to a fixed value of −20 kPa.
• Versatility: Beyond pipettes, it can test small pumps, containers, and piping with capacities up to roughly 50 ml.
• Data Connectivity: Includes an RS-232C interface for exporting test results to a PC or A&D peripheral devices like the AD-8121B printer.
• Protection: Features a replaceable air filter to shield the tester's internal pump from dust intake.

• Daily Maintenance: It allows for high-speed checking of laboratory equipment to identify units that need immediate repair or lubrication.
• Preventative Maintenance: Lab managers use it to build solid integrity records and avoid costly major repairs by catching small leaks early.
• Pre-Calibration Screening: It serves as an initial check before performing more time-consuming gravimetric calibration tests using pipette accuracy testers.

• Depressurization Value: −20 kPa ± 20% (Fixed).
• Pressure Tolerance (Internal): +0.2 kPa per 10 seconds.
• Pump Operation Time: Up to 6 seconds.
• Test Duration: Typically less than 5 seconds per unit.
• Testing Range: Micropipettes from 2 µL to 10,000 µL; other items up to 50 ml capacity.

• Pressure Tolerance Setting: +0.1 to +20 kPa (Adjustable in 0.1 kPa units).
• Monitoring Time: From 0.5 seconds (Adjustable in 1-second increments).
