45 AC Safety Volt Check 50-1,000 Volts AC with Visual Alert by Test Products International

TPI AC Volt Testers. Determine the presence or absence of AC voltage without disconnecting the system in question.

The TPI 45 is essential to anyone determining the presence or absence of electrical voltage between 50-1,000 AC. The TPI 45 allows the user to detect a defective ground before an individual is exposed to injury. Simply touch the plastic tip to a connection point or move it along a wire. If AC voltage is present, the tip will glow red. Defective grounds can cause either voltage or an electrical field to be present on a metal casing. Both of these conditions can be detected by using the TPI 45.

Features

• Detects 50-1,000 Volts AC
• Bright red glow indicates voltage
• Senses voltage without metallic contact
• UL listed
• "AAA" alkaline batteries included
• No switch required, always 'on' ready for use
• Lifetime warranty

Applications

• Electrician
• Electronics
• Emergency
• Home Owners
• Maintenance

44428 EclipSmart Universal Solar Filter by Celestron

Turn your telescope, spotting scope, or DSLR camera into a solar scope! The EclipSmart Universal Solar Filter is a must-have accessory perfect for viewing the Sun and eclipses like the upcoming 2023 Annular Solar Eclipse and 2024 Total Solar Eclipse. Affordable, easy to use, and best of all, Solar Safe, this filter conforms to the ISO 12312-2:2015(E) international safety standard. The EclipSmart Universal Solar Filter has a solar filter aperture of 60mm and works with any optic or lens measuring 75 to 100 mm in diameter, including telescopes, spotting scopes, and DSLR camera lenses. The solar filter fits around your optical device with adjustable side panels that secure with a rubber band for a snug fit. We include (2) rubber bands, but we recommend that you change out the bands frequently. To replace use #32 rubber bands. When it's not in use, fold the filter flat and place it inside the reusable bag.

If you plan to use this filter with your DSLR camera, we recommend adding a sunshade to the camera lens. This will expand the lens diameter and allow for a more secure attachment to the filter using the rubber bands. We also recommend using a tripod, monopod, or other stabilizing device with your camera setup. You can use your camera and filter intermittently over extended periods of up to several hours, but do not point your camera and filter directly at the Sun for more than three continuous minutes.

Never use this filter if your camera has an optical viewfinder. If you are uncertain about the type of viewfinder on your camera, do not use this filter. Always ensure that the filter is placed directly onto the camera lens during imaging, never between the viewfinder and your eye.

If you would like to use tape to secure the filter to your optic, Celestron recommends low-tack painter's tape to prevent any potential damage to your optic.
