- Tænd: Once the filter assembly is securely installed, reconnect the turbidimeter to power and turn it on.
5. Betjening
The filter assembly plays a crucial role in preparing samples for turbidity measurement. Its primary function is to remove particulate matter that could interfere with accurate readings or damage the turbidimeter's optical system. Once installed, the filter assembly operates passively as part of the sampstrømningsvejen.
- SampForberedelse: Sørg for samples are prepared according to USEPA Method 180.1 guidelines and any specific instructions for your turbidimeter.
- Måling: Proceed with turbidity measurements as outlined in the Hach 2100AN Turbidimeter manual. The filter assembly will condition the sample as it passes through.
- Overvågning: Regularly monitor the performance of the turbidimeter. A decrease in flow rate or inconsistent readings may indicate a clogged filter.
6. Vedligeholdelse
Regular maintenance of the filter assembly is essential for optimal performance and accurate results.
6.1. Rensning
- Frekvens: Clean the filter assembly as needed, or at recommended intervals specified by Hach for your application.
- Procedure: Disconnect the turbidimeter from power. Carefully remove the filter assembly. Rinse the exterior with deionized water. For internal cleaning, follow specific instructions provided by Hach for the filter element type. Avoid abrasive cleaners.
6.2. Udskiftning af filter
- Indikatorer: Replace the filter element when there is a noticeable decrease in sample flow, persistent inconsistent readings, or if the filter appears visibly clogged or damaged.
- Procedure: Power off and unplug the turbidimeter. Remove the filter assembly. Disassemble the housing (if applicable) to access the filter element. Replace with a genuine Hach replacement filter. Reassemble and reinstall the filter assembly.
7. Fejlfinding
If you encounter issues with your Hach Filter Assembly, consider the following:
- Lav Sample Flow: Check for blockages in the sample lines or a clogged filter element. Replace the filter if necessary.
- Inkonsekvente læsninger: Ensure the filter assembly is correctly installed and not leaking. Verify the filter element is clean and not expired.
- Lækage: Confirm all connections are tight and O-rings (if present) are properly seated and undamaged.
For persistent issues, refer to the Hach 2100AN Turbidimeter manual or contact Hach technical support.
