AL400 & AL410

The AL410 and AL400 give you mobile devices in a modern design with the analytical features of laboratory photometers. All important water analysis parameters from A(luminium) to Z(inc) are covered by these two devices. Combined with the high precision of AQUALYTIC® reagents, a reliable and quick analysis of water samples is guaranteed. Reagent tablets, powder reagents, liquid reagents, or cuvette tests are used depending on the method.
AQUALYTIC AL400Six long-lasting LEDs serving as a light source in combination with interference filters guarantee the highest precision. The devices are designed without moving optical parts and thus have a maintenance-free measuring unit. Up to 1,000 data records can be stored in both the AL410 and the AL400.

The AquaLX® app, available free of charge, offers the possibili- ty of transferring measurements to smart phones or tablets via Bluetooth®. The data management then enables analysis and export as a CSV file or graph via email. The app is available free of charge for AndroidTM and iOS®.

The proven AL400 photometer uses the classic infrared interface with which data can be transferred by means of the IRiM module to the PC or laptop.

N.I.S.T. Traceability

The instrument has a factory calibration, which is related 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)


With the help of an external mathematical program, the corresponding polynomial is created from data pairs (concentration/absorption). A known polynomial may also be used. 25 order polynomials (y = A+Bx+Cx2 +Dx3 +EX4 + FX5) can be stored together with user-specific parameters such as wavelength, measuring range, unit and number of decimals.


This function can be used to measure 2 to 14 known standards. On the basis of the concentrations/absorption pairs obtained, the photometer will calculate a linear interpolation between the measured points. Up to 10 methods can be stored for further sample measurements.

Delivery Content

The instrument is supplied complete and ready-to-use incl. 4 batteries, 3 vials ø 24 mm, 3 vials ø 16 mm, 1 adapter each for 16 mm and 13 mm vials, stirring rod 13 cm, brush 11 cm, screw driver, guarantee sheet, certificate of compliance, instruction manual, carrying case with water resistance foam, but without reagents.

Order code:
AL400: 4214020 

AL410: 4214025

Please specify the reagents or parameters required at time of order.

Infra-red data transmission modul IRiM

The IRiM (infra-red interface modul) uses modern infra-red technology to transmit measurement data from the AL400 photometer to one of 3 optional interfaces. These interfaces can be used to connect to a PC, a USB printer1) or alternative a serial printer2). The interface which is selected is displayed by an LED function indicator. The user can switch between the interfaces using the „Select“ button.

The unit is supplied complete with data logging software providing easy and rapid transfer of data to the PC. As an option the data can be saved as an Excel sheet or a .txt file. Measurement data can quickly be printed out, using a specified1) USB or alternative a printer with a serial plug-in connected to the IRiM.

1) USB printer: HP Deskjet 6940
2) each ASCII printer

Delivery content: The IRiM is delivered ready for use, with the following accessories: USB cable, 4 batteries, screwdriver, CD-ROM, operating instructions and guarantee certificate
