pH56 Pocket-size pH / Temperature Meter with Replaceable Electrode by Milwaukee

Waterproof pH testers with Large dual-level LCD that displays pH and temperature (°C or °F).

The large display shows readings in an extended range from -2.0 to 16.0 pH (pH56 has a 0.01 pH resolution) and simultaneously shows temperature from -5.0 to 105.0°C or 23.0 to 221.0°F.

They have a stability indicator and hold function that freezes the display for easy and accurate recording.

The large display also has graphic symbols to guide you through all operations.

Complete with a temperature probe for faster and more precise temperature measurement they compensate automatically for temperature.

Calibration is made automatically in 1 or 2 points with memorized standard and NIST buffer sets. Auto power OFF saves battery power after non-use.

The double-junction electrode can be replaced in a very fast and simple way! The modular design allows easy electrode and battery replacement.

VTB-NK-002 Video ToolBox Software Without USB Key by Zarbeco

Video Toolbox™ is the easiest way to display and capture video on your laptop or desktop computer. Save a single image, a movie, a time lapse sequence, or capture the image directly into your favorite image-editing software (like Photoshop™) for enhancement or annotation. Print or e-mail images without leaving the program.

Video Toolbox™ provides the tools you need to produce high quality images for live display or capture. Interactively adjust brightness, contrast and color settings. Zoom-in up to 4x without pixelation. Make precision measurements directly on the live image. Add labels, markers, even freehand drawings right on the live image. All features work on the live image so there is no need to save an image before drawing on it or taking measurements.

Plug-ins are available which increase the capability for image enhancement and automation. You can even write your own Video Tools.

Video ToolBox works with most USB, USB 2.0 and FireWire cameras which use DirectX WDM drivers and is included with Zarbeco-made products. For analog video cameras, look at our USB VideoLink adapters which put full-speed video into any computer including laptops.

72252 Ultima 8x42mm Porro Binocular by Celestron

See it and take it all in, wherever you are. The Ultima 8x42mm binocular has a wide 7.5° field of view, nearly four hundred feet wide when measured at a distance of 1,000 yards. It's the perfect choice for watching deer move through a meadow or a home run ball fly into the bleachers without moving your binoculars. But the possibilities don't stop there. Ultima binoculars are great for almost any activity, including sporting events, sightseeing, birding and wildlife observation, hiking, and more!

These classically styled binoculars use their Porro prism optical design to provide optimal image clarity and depth of field. Their widely spaced objective lenses enable enhanced triangulation between binocular and subject, presenting the observer with a rich, three-dimensional image that only traditional Porro prism binoculars can offer.

Coatings and Prisms

Ultima binoculars feature fully multi-coated optics. A binocular can be considered "fully multi-coated" when all glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye. The prisms inside Ultima binoculars are made of high quality BaK-4 glass so that more light is reflected off their internal faces and passes through to the eye. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images.

The Body

A durable, synthetic rubber-armored, aluminum housing protects your Ultima binoculars from damage without weighing you down. Viewing through Ultima binoculars is comfortable for both eyeglass wearers and non-eyeglass wearers, thanks to the synthetic fold-down rubber eyecups. What's more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. Ultima binoculars can stand up to even the toughest outdoor conditions.

Perfect for a Variety of Uses

The Ultima 8x42mm binocular features a close focus of just 13 feet, making it perfect for birders and wildlife observers, general naturalists, museum visiting, and any other activities where close-up viewing may be necessary. For distance viewing, the 8x42mm model offers an ultra-wide field of view so you can easily follow subjects such as birds or insects in flight, athletes on the sporting field or performers on a stage as they move with less need to move the binoculars.

Ways to Observe

Keep your Ultima binocular at the ready with the comfortable included neck strap. It's also tripod-adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (photography through the eyepiece). The tripod adapter is sold separately. The binocular also includes a protective padded case for storage and transport.

Accessories Included

Ultima includes an adjustable neck strap that you can customize to be most comfortable for you. The binocular also includes a protective soft case, and eyepiece and objective covers for storage and transport, so you can take it anywhere with confidence.

• Porro prism binoculars provide an enhanced three-dimensional image of the subject
• Wide 7.5° field of view allow you to see the entire scene all at once
• BaK-4 prisms and fully multi-coated optics deliver maximum light transmission through the optical path
• 13' close focus for detailed observation of subjects in close proximity

WD-00651-74 Traceable® pH Standard Buffer with Calibration, Clear, pH 10, 4 L by Oakton

Oakton pH buffers are compared against, and are traceable to, NIST Standard Reference Materials. Each bottle includes a NIST-traceable calibration report stating accuracy at 25°C to ±0.010 pH. Color-coded and colorless buffers are available in 500-mL, 1-L, or 4-L packaging sizes. Additional values and packaging sizes are available. Store at room temperature.

Certified Reference Materials (CRM) meet federal, state, and or local agencies' strictest mandates, and deliver exact calibration results for any pH meter. A2LA ISO/IEC 17025:2005 (1750.01) (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional accreditations include ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met.

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.

NIST-traceable reference materials include a calibration report from an ISO 17034 and ISO 17025 accredited laboratory
