CD610 TDS Tester with ATC and 1 point manual calibration by Milwaukee

The Milwaukee CD610 Total Dissolved Solids High Range (PPM) Pen is designed for aquariums, pools and education and many other applications. The CD610 helps make sure that you keep your fish tank water clean and healthy. It is a cost effective tool for teacher's science labs. Keep PPM in your target range to help your achieve better results.

DESIGN FEATURES

• Measures Total Dissovled Solids (PPM) direct and with automatic temperature compensation.
• Ideal range for aquariums and pools (0 to 10000 ppm).
• Units in ppm easily convertable to μS/cm.
• Factory calibrated with the ability to recalibrate if needed.
• Automatic Temperature Compensation (ATC).
• 350 hours continuous use (4 x 1.5V batteries included).
• Simple one point calibration.

MAINTENANCE

EC/PPM electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap or DI water after every use.

CONVERTING TDS TO EC

The Milwaukee TDS/PPM Pen, like all TDS meters, provides a reading measured in parts per million of contaminates per unit of volume in a solution.

TDS/PPM is often converted to uS/cm. Different scales include the 500 scale, 650 scale and the 700 scale.

Your TDS/PPM reading can be approximately converted to μS/cm as shown in the examples below.

1 ppm = 2 μS/cm on the 0.5 factor scale

1 ppm = 1.43 μS/cm on the 442 scale or .70 factor scale

WD-00651-00 Traceable® pH Standard Buffer with Calibration, Clear, pH 4; 500 mL by Oakton

Oakton pH buffers are compared against, and are traceable to, NIST Standard Reference Materials. Each bottle includes a NIST-traceable calibration report stating accuracy at 25°:C to ±0.010 pH. Color-coded and colorless buffers are available in 500-mL, 1-L, or 4-L packaging sizes. Additional values and packaging sizes are available. Store at room temperature.

Certified Reference Materials (CRM) meet federal, state, and or local agencies' strictest mandates, and deliver exact calibration results for any pH meter. A2LA ISO/IEC 17025:2005 (1750.01) (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional accreditations include ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

NIST-traceable reference materials include a calibration report from an ISO 17034 and ISO 17025 accredited laboratory

• Choose from clear or color-coded standards from common calibration points
• 500 mL (16 fl.oz.) capacity
• Calibrate at pH 4
