08006-23 Dry Block/Incubator Liquid-In-Glass Thermometer; 20 to 100C, PFA Safety Coated, 76mm Immersion, Organic Liquid Fill by Digi-Sense

These thermometers are designed for use in specific applications. These Durac thermometers feature markings that are permanently printed on the glass, individually serialized, and red spirit liquid that has a dark scale contrasts against a white background. Some thermometers are PFA coated for added safety which may cause a slight change in accuracy up to 1 division.

Dry block thermometers - designed for use in all standard heating blocks and water baths with most having arrows indicating critical temperatures.

COND115N Non-Bluetooth Conductivity + Temperature Tester (0 to 100 uS/cm) by Jenco

Waterproof, economical conductivity/temperature tester with long useful life.

Like its Bluetooth sibling, the Wand Non-Bluetooth Series' main focus is to deliver accurate and repeatable conductivity results easily and affordability. This was accomplished by starting Jenco's longest running and very popular tester series and updating it with better electronics for better accuracy, replacing the potentiometer with buttons with tactile feedback and protecting the upgraded internals with an IP67 waterproof housing.

Improved Reading Quality

• 1 Point calibration
• ±1% F.S. accuracy

Simple Operation

• Clear, large LCD displays conductivity and temperature
• Button operations with tactile feedback
• IP67 waterproof housing

Available Configurations

Single parameter pH, ORP, conductivity and TDS models with temperature. Conductivity and TDS comes in three different models each for three different measurement ranges.

WD-00652-66 Traceable® One-Shot™ Conductivity and TDS Standard, 1000 μS; 6 x 100 mL Vials by Oakton

• Oakton® Traceable® conductivity and TDS standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25°C-convenient!!
• Average accuracy at 25°C is ±0.25 microsiemens for 1, 5, 10 microsiemen (μS) solutions, or ±0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
• Conductivity options range from 1 to 200,000 μS/cm
• Individually-tested solutions are certified by the bottle - each bottle is analyzed for the best accuracy

METHODS SUPPORTED

Certified reference material meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO. Traceable® Conductivity Standards complies with and is essential for use in these official methods: AOAC 973.40, EPA 120.1, Standard Method 2510 (APHA, AWWA, WEF), ISO 7888, DIN 38404, ASTM D1125, USGS I-1780, USP 645, and for A2LA/NVLAP accreditations/ISO 9000 certifications. Material may be used to calibrate all conductivity meters and to determine all conductivity cell constants.

A2LA ACCREDITATION ISO/IEC 17025:2005 (1750.01)

To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory. A2LA accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. Conductivity Standards are produced in an A2LA accredited ISO/IEC 17025:2005 (1750.01) calibration laboratory. Additional certifications include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer).

• All Oakton® Traceable® conductivity standards are NIST-traceable reference materials
• Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory
• These standard solutions let you calibrate conductivity instruments to ensure accuracy
• If unopened, shelf life is one year; once opened, shelf life will vary by solution value
• Use when readings are expected to be around 1000 μS/cm

INCLUDES

temperature compensation chart, TDS conversion chart, and NIST-traceable calibration certificate with data.

90311-22 Blood Bank Verification Thermometer; -5 to 20C by Digi-Sense

Accurately monitor temperatures in freezers, refrigerators, incubators, ovens, and other environments where stability is required. All thermometers are supplied in a glass bead filled unbreakable plastic bottle and can be removed from the bottle for recalibration. Use the magnetic attachment with pressure-sensitive backing to attach the bottle to a metal wall or door.

Thermometers feature permanently fused markings, blue spirit liquid, white background glass; are also individually serial numbered. Include an statement of accuracy and a triangular-style antiroll fitting.

• An individually serial number is printed on the thermometer stem
• Nonmercury blue spirit liquid
