WD-35420-01 RS-232 Interface Cable for Advanced pH/Ion Meters by Oakton

Replace electrodes when they break, no longer hold calibration, cannot be rehydrated, or are not compatible with your sample. For your convenience, cables, power adapters, and other accessories are available for your Oakton meters and pocket testers.

Works with 2700 and 450 meters.

08610-05 Traceable® Indoor/Outdoor Analog Dial Clock with Calibration by Digi-Sense

Clocks show temperature range in F° and C° and gives the time of day to the second. Time is given with 0.01% quartz-crystal accuracy. Durable wall clock features an o-ring sealed waterproof/dustproof ABS impact resistant housing that is ideal for areas that continually need to be wiped down and the outdoors.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory

Includes

One AA battery and NIST-traceable calibration certificate with data.

Part Number: 10L-466

Compatible sampling tube for Gas-Pro. Select length from list and whether standard or low adsorption material for reactive gases. All include tube insert to enable attachment to flow plate.

TDSK18/G Conductivity Solution, 8.4ppm/18uS, 1Gal by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.

08068-20 Irreversible 8-Point Vertical Temperature Label, 100-150F/37-65C; 25/Pk by Digi-Sense

Labels are made up of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows. Each element changes color distinctly as its rated temperature is met or exceeded. The changes to the label are irreversible, providing a temperature history of the surface being monitored. The labels will not delaminate when removed, allowing them to be attached to an inspection report to serve as a permanent record. Ideal for use in the food, automotive, molding and metal working industries. Accuracy is ±1.8°F below 212°F and ±1°F above 212°F. Shelf life: 1 year after date of purchase.

Reliable proof that the product was maintained at the correct temperature

• Used as a quick inspection tool that the product is in usable condition during the shipping and receiving process
• Save time and money due to costly recalls
• Self-adhesive design
