MTL’s AH225 series is a complete automated filter processing solution. It has been engineered by weighing experts to implement the carefully observed methods required by precision weighing applications to ensure accurate results.

Technicians load the input silos with filters placed in individual carriers and activate FWS, which controls the unit and weighs each filter according to administrator selected instructions. Personnel are free to perform other duties. Each filter’s bar code is read. It is then taken to the balance where it is inserted and placed on the balance pan in the exact came position each time.

How the weighing takes place is determined by you by adjusting the administrator set parameters. For example, length of time and weighing method are configurable.

During the weighing process, the MTL software performs a buoyancy correction and measures barometric pressure. Temperature and humidity are also monitored with NIST-traceable equipment to document environmental compliance. The software gives you the control you need to stop weighing at any time in the event of an environmental excursion.

The system issues weighing reports for each filter, helping you keep on top of quality control. This data is stored in an SQL™ database, which can then be accessed by a network server.

Quality Control Made Easy

Human operator error can be caused by many things. A person tends to get tired of doing the same job over and over again. Operation fatigue, poor judgment, and inconsistent accuracy are all factors of manual weighing.

To fix this problem, we have designed a product to make the weighing process a lot easier, faster, and more accurate.

With an automated weighing machine, or Autohandler, you never have to worry about correct results, weighing repeatability, or manual fatigue.Our system will take care of it all for you while giving you the quality control you need, as well as weighing traceability and documentation. Direct read method tares the balance and records data after receiving a stable result from the balance. A-B-A drift corrected approach also calculates for drift from beginning to end of a weighing. There are also statistical analyses of calibration weight data and reference filter data with quality control flags that let you know what is out of tolerance. The MTL Autohandler also performs a daily balance performance analysis with subsequent documentation so you can know, day by day, that you are getting accurate results. It also provides documentation of every and all filters, storing which data belongs to which filter so you can recall it in a moments notice. It’s all right at your fingertips.

• Weighing time: 2 min per filter using direct read; 3 min per filter using drift corrected ABA weighing.

• AH225 performs automated static discharge using Po-210 and MTL’s internally developed Faraday pan before & during weighing of a filter.

• Repeatability: check standard: .25 ug; filter: .75 ug

• Filter carriers or machine readable bar-coded filters are scanned by AH225 for individual identification and easy tracking.

• Reduce human effort and error while increasing throughput and laboratory efficiency.

• Compatible with METTLER TOLEDO™ and Sartorius™ balances designed for microgram weighing (Sartorius SE2 is compatible, SE2-F is not compatible at this time)

• Dimensions: 42”L x 25”D x 25”H. Power: 120 VAC
