Working principle: The Model FL30 fluorescence spectrophotometer has four excitation detection channels, which can simultaneously detect turbidity and three types of tracers, and can also be equipped with an optional conductivity sensor.

ALBILLIA GGUN-FL30, Switzerland

Field fluorescence spectrophotometer for surface water

Diameter: 160 mm; Height: 170 mm

Usage: Immerse directly into surface water bodies (0-20 meters), springs, or used for rapid testing of laboratory samples. Quickly connect accessories and 6mm pipes. Up to 4 light sources, covering the entire spectral range.

Encapsulation: Stainless steel. Aluminum can be optionally installed.

The probe is connected to a waterproof data recording box through a 4-core signal wire, which contains 1 to 2 batteries. The data logger provides power, clock, and data storage. The signal is transmitted in digital form. Data recording can be connected to any computer through the RS232 interface. In unmanned situations, the data logger can store up to 4 * 60000 sets of samples and temperature data (with an accuracy of 0.01 ° C) on a compressed memory card (CF card).

List of accessories and introduction to their main functions

Introduction to each component inside the box

1. Chassis: Contains the host (data logger), as well as the battery and connecting wires. The wire part of the equipment has been fixed and integrated for installation, and the body itself is made of plastic material. Therefore, when removing it, be careful not to touch or drop it, otherwise it may cause damage to the equipment!

The chassis itself adopts waterproof design, so try to avoid immersion in liquids as much as possible. In addition, the probe interface exposed from the chassis does not have waterproof function without connecting cables. Pay more attention when using it.

2. Probe: The probe model shown in the picture is FL30, which is a surface water probe with a working depth of less than 50M. The use of the probe will be explained in detail in the following text.

3. CD

4. Cable

5. USB connection cable

6. Wash the brush

7. Hexagonal tool

8. Sample injection interface

9. Plug (rubber stopper)

10. Battery

Connect the host and probe:

There is a protruding opening on one side of the chassis box, with an extended interface. On the interface section, you will see an 8-hole terminal post with a red dot at the upper end of the outer wall of the port. Take out the cable and remove the metal cap on the end with the metal cap. Align the red dot on the port of the cable with the red dot on the interface and insert it completely. After inserting, you will hear a "click" sound.

Gently retract the rubber cap on one end of the cable until the metal joint is exposed. Align the red dot on the cable port with the red dot on the probe interface and insert it completely. After inserting, you will hear a "click" sound.

After completing the above steps, the host and probe are connected.

　　The completed effect should be as shown in the following figure

After completion, what needs to be done is to restore the rubber sleeve of the probe and completely wrap the interface. The following figure

Introduction to the Probe Part (FL30)

FL30 is divided into two parts: the main body, the upper cover, and the lower cover. There is a sampling port on each of the upper and lower covers. When sampling, pay attention to the fact that the port on the upper cover should face the direction of the water flow, while the port on the lower cover should be consistent with the direction of the water flow. The direction of the exit can be adjusted according to the actual situation. The adjustment method is to use a 5MM hex wrench to unscrew the 3 screws on the cover, and then adjust the direction. After adjustment, tighten it.

In many cases, laboratories generally adopt field sampling and indoor testing methods, so FL30 also has another laboratory measurement method. If the laboratory has sampling equipment, then simply screw the sampling interface at the inlet and outlet of the probe. As shown in the figure:

Sample is injected into the inlet and liquid is discharged from the outlet. A rubber tube can be connected at the interface to complete the injection, and the diameter of the injection port is 5mm.

If the measured sample does not need to be collected, the upper and lower covers can be removed, the lower cover can be blocked with a rubber stopper, and the sample can be injected directly with the upper cover.

After the measurement is completed, simply remove the rubber stopper and release the sample. When measuring in this way, it is particularly important to first try to add the sample at a constant speed without generating bubbles. In addition, after filling the sample, the top cover must be covered or blocked from light. Install the lower cover rubber stopper as shown in the diagram.

When the probe is not suitable, use a brush to clean the inside of the probe to avoid tracer adsorption on the light-emitting tube, which may affect the next use. Each time the probe is used, it also needs to be cleaned with a brush before use.

After connecting the CR850 data collector, the data can be viewed through the collector's display screen

Press Enter to enter, then select data, press Enter, then select Real time Tables and press Enter, select Test and press Enter to view the measurement data. The Esc button is a up, down, left, and right movement button marked with up, down, left, and right arrows that returns to the upper menu.

When the battery level is low, remove the green sheet power supply head of the CR850 collector to charge the battery.

Please refer to the CR850 documentation of LoggerNet4.0 for the method of reading data by connecting to a computer. The LoggerNet4.0 software and USB driver need to be installed.

This system is set with three collection times and data storage times at the factory, namely 300S, 600S, and 900S. The 300S collection interval can store data for about 500 days, the 600S collection interval can store data for about 1000 days, and the 900S collection interval can store data for about 1500 days. Before the data is fully stored, it must be read out. The shorter the collection time, the greater the power consumption, and the shorter the storage days. The system defaults to collecting data once every 900S when it leaves the factory.

When not in use, unplug the power supply green sheet of CR850. When in use, simply plug in the sheet to make the instrument work. Ensure that the battery is fully charged before each outdoor trip.
