Description

AL250 & AL250+

The AL250 models each offer one test method, while the AL250+ units are programmed for a number of different parameters. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling.

The calibration and software-based adjustment options mean that the AL250 is also suitable for use as a testing instrument. The tests are conducted using either AQUALYTIC tablet reagents with long-term stability and a guaranteed minimum 5 or 10 year shelf life, VARIO powder reagents or using liquid reagents.

Delivery Content: Each AL250 is supplied in a case complete with 9 V battery, 3 round vials with cap, tablets and/or liquid reagents or VARIO Powder Packs, accessories, instruction manual, guarantee sheet and a certificate of compliance.

Scroll Memory (SM)

To avoid unnecessary scrolling for the required test method, the instrument memorizes the last method used before switching off the instrument. When the instrument is switched on again, the scroll list comes up with the last used test method first.

N.I.S.T Traceability

to internal standards which are not N.I.S.T traceable. The instrument may be calibrated by the user in a “user calibration mode” with N.I.S.T traceable standards.
(N.I.S.T. = National Institute of Standards and Technology)

Calibration certificate

Beside the “Certificate of Compliance” which is supplied with each AL250, calibration certificates are available at cost on request. Calibration certificates are individually supplied per instrument and per method.

The Calibration Certificate has to be ordered together with the new instrument and cannot be delivered at a later stage.

Reference Standard Kit

The reference standards are designed to check the accuracy and the reliability of the results. The shelf life of reference standards is two years from the date of production, provided that storage and use are in accordance with the instructions provided.
