TDSNA1 Conductivity Solution, 497.7ppm/1000uS, 1Qt 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.

7182112 Ball Float including 3x5 mm reductor needs tubing by WatchGas

For a confined space clearance measurement, a sampling hose is attached to a pumped gas detector. An open end of the hose, runs the risk of allowing dust and liquids to enter the sampling hose, blocking the hose and delaying the work. Ball floats are a perfect way to ensure no liquid or dust can enter the sampling hose.

WatchGas has completely redeveloped the ball float to make it suited to heavy duty work in every way.

The ball float is made in one piece to make it more resistant and durable in comparison to ball floats that are made from two hemispheres glued together. The material is chemical-resistant, antistatic and nonadsorbent, therefore it does not interfere with your measurement. Also, its bright yellow color makes it visible, providing contrast in dimly-lit situations.

90225-15 Traceable® Pen-Style Digital Thermometer with Calibration; 8" L, 302F by Digi-Sense

NIST-traceable precalibration means you get reliable measurements right out of the box, saving you time and money! 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.

Stainless Steel Stem, °F/°C switchable ranges, one-second display update in Celsius scale, and ten-second display update in Fahrenheit scale. Use ON/OFF button to conserve battery life.
