93711 NexImage 5 Solar System Imager (5MP) by Celestron

Celestron offers a wide array of high-quality, affordable, and user-friendly planetary imagers!

Capture high-resolution planetary, lunar and solar images with almost any telescope with the NexImage 5 Solar System Imager. Combined with the included software package, NexImage 5 brings out tremendous detail and produces images rivaling those taken with astronomical cameras costing hundreds more.

Simply point your telescope at the Moon or a planet and record a quick video. The included software analyzes each frame of video, throws away the fuzzy ones, and perfectly aligns the remaining images. The result is a bright, clear image with the maximum amount of color and detail. NexImage 5 is a great way to get started with astroimaging, especially if you live in a light-polluted area. If you can see the planet the sky, you can image it with NexImage 5!

• 5 Mega pixel color sensor with Micron® DigitalClarity® technology to dramatically reduce image noise levels
• Small pixel sizes provide sub arc-second planetary detail with most telescopes
• View and capture live video on your computer
• Software automatically filters out video frames most affected by poor atmospheric conditions, leaving only the sharpest, clearest frames to be stacked and aligned into one high-quality image
• Camera control software allows you to manually change the gain, contrast, exposure time, frame rate and color saturation using your PC
• Selectable "region of interest" sub-framing
• Machined aluminum 1.25" adapter barrel with C-threads for direct threaded connection to almost any telescope
• Can be used with standard 1.25" eyepiece filters
• Integrated IR-cut optical window
• 2x2 and 4x4 binning capability in color

• Includes USB 2.0 cable

90000-29 Traceable® Extreme-Accuracy Digital Thermometer with Calibration; 0.00/25.00/37.00C by Digi-Sense

Four Traceable International Standards Digital thermometers provide the exact readings required for critical requirements, quality control checks, and routine measurements. Units read 0.00, 25.00, 37.00, or a combination of all three with a resolution of 0.01° and an accuracy ±0.05°C within ±2°C of standard. Units read in °C and °F.

Impervious stainless-steel probe

Stainless-steel probe supplied with units shows the slightest temperature change. Probe is triple purpose for liquid, air/gas, and semisolids. Accurate readings with tip penetration of 1/3-inch. Probe has a diameter of 1/8-inch, stem length of 6-1/4 inches, overall length of 9 inches and a cable length of 5 feet.

Unit conforms to ITS-90, International Temperature Standard

Absolute high-precision thermometer is ideal for measuring temperatures in water baths, cuvets, gas systems, reagents, standards solutions, ovens, incubators, pharmaceuticals, petroleum products, foods, and wastewater.

Records time and date for MIN/MAX readings and hi/lo alarm alerts

Display shows minimum/maximum and current temperatures. MIN/MAX monitors readings overnight, on weekends, or for any time period and displays the exact time and date when the MIN/MAX temperature occurred. Alarm provides two visual (LEDs) and two audio alerts when temperature rises above or falls below high and low set points. Unit displays the exact time and date when dual thermometer alarms are triggered. Alarms are programmable in 0.1° increments. Visual and audible alarms signal continuously (for days) even if temperature returns to non-alarm range. First thermometer ever designed to permit user one-button calibration.

• Resolution is 0.01°
• Displays date and time of min/max temperature
• High and low settable alarms
• Traceable to NIST for accuracy

Includes

Stand, Velcro®, magnetic strips, and wall mount allow placing thermometer anywhere. Supplied with a Traceable® Certificate, stainless-steel probe, and two AA batteries for continuous, 1-year always-on monitoring.

Measuring Range: -50 to +275 °C

WD-00652-42 Traceable® Conductivity and TDS Standard, Individually-Tested, 5 μS; 500 mL 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.
