TDSK300000/P Conductivity Standard Solution, 300,000uS (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.

MA9009 pH 9.18 Calibration Buffer Solution @ °C/77 °F: accuracy +/- 0.01 pH - 230 ml by Milwaukee

Probe calibration is a simple procedure for optimal performance and should be done any time your readings become suspect. Calibration should be performed at least once a month.

MA9009 is a lab grade pH 9.18 buffer solution certified to meet the standard to an accuracy of ±0.01 pH removing the inaccuracies involved with mixing buffers.

Milwaukee solutions are designed to help you achieve reliable and repeatable pH measurements while extending the life of your electrode.

DESIGN FEATURES

• pH 9.18 Calibration Buffer Solution (230 mL)
• Fundamental for the correct use of electrodes and for obtaining the most accurate and reproducible readings
• Sealed against light with air tight, tamper proof cap
• Ideal for fast calibration
• Simply open, pour into a beaker or container and insert the tester or electrode to start the calibration process.

BK-4100-P Beaker, Plastic 100mL by AquaPhoenix

Continuously use Nalgene™ PMP Griffin Low-Form Beakers at temperatures of 150°C with intermittent service to 175°C. These polymethylpentene beakers have the transparency of glass, excellent chemical resistance and heat tolerance. All sizes of beakers have easy to read, silk-screened graduations.

BU5002-P Buffer, pH 2.00, 500mL by AquaPhoenix

• ± 0.02 at 25°C

pH Buffer should be used regularly, typically every day the meter is used to calibrate your pH meters. Pour buffer into a clean separate container and never return used or unused buffer back into the container. Always keep tightly capped and adhere to the expiration date which is printed on the label.

Traceable to NIST

44401 Microscope Calibration Slide by Celestron

Ensure accurate readings from your microscope with the help of Celestron's Microscope Calibration Slide. Also known as a stage micrometer, the Celestron Microscope Calibration Slide is a standard 1" x 3" glass microscope slide that features an etched scale that is 1mm in total length and subdivided into 100 equal divisions.

The stage micrometer fits on your microscope's stage, allowing you to ensure your specimen measurements are correct. If you have a digital microscope and or a traditional microscope with a digital imager attachment, a stage micrometer is essential for calibrating the microscope's software settings. You can also use the stage micrometer to manually measure specimens that are 1/100th of a millimeter or larger, such as microfibers. If you have a non-digital microscope (e.g., Celestron Labs), you can use the stage micrometer to calibrate the microscope's eyepiece reticles and determine the field of view of different objective lens and eyepiece pairings. If you find yourself changing objectives and eyepiece reticles often, using your calibration slide regularly will help you maintain measuring accuracy.

Compatible Microscopes

The stage micrometer works with a wide range of Celestron microscopes and imagers to measure specimens or determine your microscope's field of view.

• Precise stage micrometer glass slide for calibrating your microscope's camera or imager
• 1mm ruler with 100 subdivisions to accurately measure specimens as small as 0.01mm
• Standard 1"x3" slide fits easily on a traditional microscope stage
