90205-24 Traceable® Remote Probe Digital Thermometer with Calibration; Stick-Style, Fahrenheit by Digi-Sense

Stick-Style Remote Probe Thermometers have a 3-ft flexible cord, Min/Max memory, and simultaneous display of probe and ambient temperatures. Meter is chemical-resistant and shockproof; comes with a remote sensor and cable that can be submerged. Use as a pocket thermometer or mount for continuous use with the supplied self-adhesive Velcro® tabs.

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.

• Get accurate, reliable measurements with included NIST-traceable calibration

Includes

NIST-traceable calibration certificate with data.

CD600 TDS Tester with ATC and 1 point manual calibration by Milwaukee

The Milwaukee CD600 Total Dissolved Solids (TDS) Pen is designed for hydroponics, aquariums, horticulture, water conditioning and many other applications. The CD600 helps you make sure that your plants are receiving the right amount of nutrient or helps you keep your filters up-to-date and clean for water filtration. Keep TDS in your target range to help your achieve better results.

DESIGN FEATURES

• Measures Total Disolved (TDS) direct and with automatic temperature compensation.
• Ideal range for hydroponics (0 to 1990 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

TDS/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 Pen, like all TDS meters, provides a measure of Total Dissolved Solids (ppm) reading, of contaminates per unit of volume in a solution.

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

Your TDS/PPM readings 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
