WD-00651-00 Traceable® pH Standard Buffer with Calibration, Clear, pH 4; 500 mL 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

• Choose from clear or color-coded standards from common calibration points
• 500 mL (16 fl.oz.) capacity
• Calibrate at pH 4

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.

21024-ACC FirstScope Accessory Kit by Celestron

If you have a Celestron FirstScope telescope and want even more versatility and portability, take a look at the Celestron FirstScope Accessory Kit! It includes six separate pieces that will enhance your observations and help you learn even more about the Universe.

Get Help Finding Objects

When you are observing something big, like the Moon, it is fairly easy to point your telescope along its line of sight and get that object in your eyepiece. However, smaller objects are much easier to locate in your telescope if you have a finderscope to help do the work. This 5x24 finderscope and bracket is made to attach to the FirstScope without tools. It magnifies the view by 5X and has optics 24 mm in diameter. Once you have attached the finderscope to your telescope tube and have done some simple alignments, you will be able to point with the finder instead of the telescope itself.

Choose Your Magnification

Anyone who has a telescope will tell you that you can't have too many eyepieces. Every eyepiece offers a different magnification and a different field of view. In the FirstScope Accessory Kit, you will get two 1.25" eyepieces. One is a 12.5 mm model, and will magnify objects 24X more than your eyes alone can see. The second eyepiece is a 6 mm, and will boost the power even further, to 50X. Remember, the lower the number of the eyepiece, the higher the magnification!

See More Detail on the Moon

The Moon is beautiful, but it is bright, especially when full. A Moon Filter works the same way sunglasses do for your eyes on a bright, sunny day. The filter lowers the amount of light reaching your eye, and allows it to relax and see details that would not be visible in an unfiltered view of the Moon due to glare. The Moon Filter screws onto the barrel of all of your 1.25" eyepieces, giving you a choice of filtered magnification. (Note: Do not use the Moon filter for solar observation.)

Learn More About the Sky

TheSkyX: First Light Edition is included in the FirstScope Accessory Kit. The software comes on a DVD-ROM that can be used on PC (Windows 7, XP, and Vista) or Mac (10.4.8 or later) computers. Learn the constellations, print out star charts for an upcoming observing session, and learn how to identify planets and stars, and more!

Store & Carry Your Telescope Easily

When your FirstScope telescope and accessories are not in use, store them in this nylon tote bag! Having everything together in one easily-identifiable carry bag will make it even quicker to grab your telescope and get outside to see the latest comet, bright, shining planet, or lunar eclipse!
