S020 3.5M KCl Refill Solution, 4 oz. by Sensorex

Refillable sensors can maintain accuracy for longer time periods. This sensor type requires re-filling with KCl solution when the liquid level is about 1 below the re-fill hole. To do this, slide the protective outer sleeve up to expose the filling hole and fill the electrode to the hole level with KCl (potassium chloride) solution.

WD-00652-24 Traceable® Conductivity and TDS Standard, Batch-Tested, 10 μS; 500 mL by Oakton

• Oakton® Traceable® conductivity and TDS standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25°C-convenient!!
• Average accuracy at 25°C is ±0.25 microsiemens for 1, 5, 10 microsiemen (μS) solutions, or ±0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
• Conductivity options range from 1 to 200,000 μS/cm
• Batch-tested solutions are lot certified; a few bottles from a single lot are analyzed

METHODS SUPPORTED

Certified reference material meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO. Traceable® Conductivity Standards complies with and is essential for use in these official methods: AOAC 973.40, EPA 120.1, Standard Method 2510 (APHA, AWWA, WEF), ISO 7888, DIN 38404, ASTM D1125, USGS I-1780, USP 645, and for A2LA/NVLAP accreditations/ISO 9000 certifications. Material may be used to calibrate all conductivity meters and to determine all conductivity cell constants.

A2LA ACCREDITATION ISO/IEC 17025:2005 (1750.01)

To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory. A2LA accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. Conductivity Standards are produced in an A2LA accredited ISO/IEC 17025:2005 (1750.01) calibration laboratory. Additional certifications include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer).

• All Oakton® Traceable® conductivity standards are NIST-traceable reference materials
• Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory
• These standard solutions let you calibrate conductivity instruments to ensure accuracy
• If unopened, shelf life is one year; once opened, shelf life will vary by solution value
• Use when readings are expected to be around 10 μS/cm

INCLUDES

temperature compensation chart, TDS conversion chart, and NIST-traceable calibration certificate with data.

MI526-100 Powder Reagents for Total Chlorine (100 tests) by Milwaukee

The Free Chlorine powder reagent kit includes high-quality reagents that are ready-to-use with Milwaukee's MW10 Free Chlorine Meter. The reagents use the DPD Method with a reaction between chlorine and reagent causing a pink tint in the sample. Simply add the reagent to the sample, wait for the reaction to take place and the photometer determines the concentration based on the color. The reagents are designed for use with samples that have an expected maximum range of 0.00 to 5.00 ppm free chlorine.

DESIGN FEATURES

• Free Chlorine reagent replacement kit (100 powder reagent sachets).
• Pre-made reagents for precision and ease of use.
• Marked with expiration date and lot number for traceability.
• For use with the MW10 Meter.
