09037-21 Reversible 16-Point Vertical Temperature Label, 32-49C/90-120F; 10/Pk by Digi-Sense

These self-adhesive reusable temperature labels provide a safe, accurate, easy-to-read means for monitoring temperatures. Indicating strips use liquid crystal technology to display the current temperature at an economical cost. The strip will turns a green color when ambient temperature is reached. Shelf life: 1 year after date of purchase.

• Non-toxic / non-hazardous temperature measuring alternative
• Easy to read and unbreakable

AI1130 1413 μS/cm Conductivity Calibration Solution 8 oz. by Apera

The Apera Instruments 1413 μS/cm Standard Conductivity Calibration Solution is made of high-purity chemicals, standardized against NIST certified references at 25°C (77°F). It's ideal for the calibration of all types of conductivity meters. Since conductivity value is affected by temperature, the temperature & conductivity reference table is provided on the bottle labels for your reference.

All the solutions are double-sealed, not subject to the DOT shipping restrictions, and have a 1-year shelf life. The expiration date is printed on the bottle.

MSDS is downloadable at support.aperainst.com; The Certificate of Analysis can be acquired by requests.

Note: Store at room temperature and away from direct sunlight. Keep the bottle tightly closed when not in use. Keep out of reach of children.

TDSK80000/P Potassium Chloride TDS Solution, 80000uS/cm (Pt) 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.
