ISCO Turbidity Sampler Calibration.pdf

Okay, I need to create a concise and detailed summary of the provided document. Let me start by reading through the content carefully.

The document is titled "Salmon Forever / Watershed Watch ISCO Sampler Proficiency Checklist." It seems to be a checklist for setting up and maintaining an ISCO sampler, along with calibration data for a HACH 2100P turbidimeter. The user wants the summary in the same language as the source, which is English, and without any additional markers or titles.

First, I'll identify the main sections. The checklist includes several tasks like recording observations, checking equipment, cleaning probes, adjusting offsets, and calibration steps. Then there's a calibration certificate section with details like customer, instrument model, serial number, calibration type (Formazin and Sediment), standard values, and specific data points.

I need to make sure I cover all the key points: the purpose of the checklist, the tasks involved, the calibration data, and the contact information. Also, the calibration data includes standard values for Formazin and Sediment, output ranges, dates, and the calibration company's details.

I should mention the calibration type, the number of standards, the specific values, the output ranges, the date of calibration, and the certified by information. Additionally, the calibration process involves using distilled water and specific solutions for different turbidity levels.

I need to be concise but include all necessary details. Let me check if there are any numbers or specific measurements that are important, like the depth in feet, R² value, and the volumes used. Also, the contact information at the bottom should be included.

Wait, the user mentioned "ISCO Sampler Proficiency Checklist" and "Calibration Certificate" as separate parts. I should structure the summary to cover both sections. Make sure to note the calibration data for the HACH 2100P turbidimeter, the standard values, the output ranges, and the calibration details.

I should avoid any markdown and just present the summary in plain text. Also, check for any typos or formatting issues in the original text. The original has some symbols and maybe some missing words, but I'll try to parse them correctly.

Let me start by outlining the main components: the proficiency checklist tasks, the calibration certificate details, and the contact information. Then, I'll write the summary in a clear, concise manner, ensuring all critical information is included without unnecessary details.

ISCO Sampler Proficiency Checklist for Salmon Forever / Watershed Watch outlines procedures for setting up, maintaining, and operating an ISCO sampler, including recording field data. Key tasks: verifying current data display, checking equipment (cleaning probes, ensuring no debris or moving boom obstruction), selecting manual sampling options, using ports and flags for sample collection, and adjusting stage/turbidity offsets. Calibration data for HACH 2100P turbidimeter includes Formazin (2000 FTU) and Sediment (0.001 V ±0.002 V, 2.501 V ±0.005 V) standards, with a calibration date of 11 March 1998. Calibration involved measuring depth (2.3365 output), R²=1, and specific gravity of 4000 NTU solution (1.002 g/mL). Calibration vessel volume was 8.7 L, and 3% turbidity offset was applied. Distilled water and standard solutions were used for testing, with calculations for required volumes (e.g., 13,500 ml for 4000 NTU, 1,875 ml for 6.0 L bucket). Instrument model ISCO 88275, serial number 430, was calibrated by Olympus at 981231 R. Eads, with contact details: Port Townsend, WA 98368, 360/385-0272, fax 385-0460, email [email protected].
