37803-86 Traceable Digital Thermohygrometer with Dew Point, Memory Card, and Calibration by Digi-Sense

This thermohygrometer records data onto a standard SD memory card instead of built-in memory - the advantage being that when the memory on the SD card is full, the SD card can be simply exchanged out for unlimited data storage. The data is provided in a text report that includes date, time of day, and readings of sensors, and may be sent to any spreadsheet or database.

The unique 4-line display simultaneously shows ambient temperature, humidity, dew point, and time of day. An audible and visual alarm alerts you when temperature, humidity, or dew point levels are higher or lower than the programmable set points. User-settable parameters include date, time, sampling time, temperature unit of measure, high/low alarm set points, and auto power off.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• SD memory card stores up to 5.9 million readings
• Adjustable data logging sampling time from 1 second to 12 hours
• Maximum and minimum readings can be recalled or stored for later use

Includes

SD memory card, USB memory card reader, magnetic mounting strips, hook and loop mounting strips, bench stand, power adapter, three AA batteries, and NIST-traceable calibration certificate with data.

Our Founder's Vision, Reimagined for the 21^st Century

In the 1970s, Celestron's Schmidt-Cassegrain telescopes brought the hobby of astronomy to the masses and established Celestron as the world's premier telescope maker. Our founder, Tom Johnson, invented Celestron's proprietary method of producing Schmidt corrector plates for superior views and maximum portability. Johnson believed in creating high-quality optical instruments at an affordable price, and inspired a generation of amateur astronomers.

Four decades later, we've improved upon this design by adding cutting-edge features, while staying true to our founder's intent.

View the Universe s Most Impressive Celestial Objects

The 4SE's four-inch primary mirror packs enough light-gathering ability to observe the best that the solar system has to offer: Saturn's rings, the cloud bands on Jupiter, and geographic features on the surface of the Moon. When it comes to deep sky objects, take your 4SE to a dark-sky site and you'll see hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and more.

Revolutionary Single Fork Arm Mount

We know the best telescope is the one you will use most often. That s why Celestron's engineers created NexStar SE's unique, patented single fork arm mount. It's perfectly portable and makes setup quick and easy. What's more, the NexStar SE breaks down into several lightweight and compact pieces, making it easy to transport, even in small vehicles. You'll have no problem getting the NexStar SE to your favorite observing site, or setting it up quickly in your backyard.

Of course, it's what's inside the mount that really counts. Sturdy construction from high-quality components give NexStar SE the pointing and tracking accuracy needed to observe and follow your favorite targets with push-button ease. Use the included NexStar+ hand control to locate over 40,000 celestial objects, or take a Sky Tour and let your telescope show you the best objects currently visible.

Aligning your telescope is simple and painless, too, thanks to SkyAlign. This process makes alignment as easy as 1-2-3: just center three bright objects in your eyepiece and press ALIGN. For even easier alignment, attach our StarSense AutoAlign and your NexStar SE aligns itself!

Advanced Features Let the NexStar SE Grow with You

The NexStar SE is compatible with all the high-tech accessories advanced users love. Provide GPS coordinates to your telescope with SkySync, or add automatic alignment functionality with StarSense AutoAlign.

Its built-in wedge allows you to track long exposures. if you're interested in imaging the Moon and planets, pair your NexStar 4SE with one of our Skyris cameras. From your first observing session and for years to come, the NexStar SE is your trusted companion.
