WD-35850-12 Buffer Capsules, pH 4; 10/Pk by Oakton

Buffer salts inside capsules require 100 mL of deionized or distilled water to produce a clear pH calibration solution accurate to ±0.02 pH (at 25°C) with traceability to NIST standards. Capsules are easier to store and transport than prepared aqueous buffer solutions. Capsules are color-coded for easy identification if mixed.

Store buffer solution in an airtight container at room temperature for three weeks. Unused capsules have a five-year shelf life. Each vial contains 10 capsules.

Fresh pH calibration solution anytime and anywhere

• Each capsule mixes with 100-mL of deionized water to create a clear, 4.00 pH solution

Includes

Ten red-colored capsules.

94460-77 Traceable® Sentry Triple-Display Thermometer with Calibration; -50 to 70C, Wire Probe by Digi-Sense

Thermometers include a weatherproof remote sensor with a 10-ft. (3.05m) long 1/16"-diameter micro cable. The micro cable is ideal for applications that require a seal, such as a refrigerator, where a larger cable would interfere with the sealing of the door. Unplugging the external probe will activate an internal sensor for monitoring ambient temperature. Thermometer features a high-impact ABS plastic case, large LCD that updates every 10 seconds, and a simple one-button reset to clear the high/low memory. Supplied with Velcro® strip for wall mounting or has a flip-out stand for tabletop use.

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.

Models 94460-76 and -77 are designed for general-purpose applications

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

Includes

NIST-traceable calibration certificate with data, mounting hardware, and one battery.

08006-03 Galileo Thermometer; 64 to 80°F (18 to 26°C), 11 in. by Digi-Sense

Colorful glass thermometer is based on Galileo's theory developed over 400 years ago: in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and more buoyant as the temperature decreases - due to changes in liquid density. As temperature changes, the multi-colored balls rise and fall within the liquid-filled thermostatic tube. Lowest sphere in the top group within the instrument indicates ambient temperature.

• Hand-crafted thermometers
• Non-mercury liquid
• Five floating spheres provide both Fahrenheit and Celsius readings
• Seven inches tall
