BRESSER B-RS-190 End stop screw for rail system

Particulate matter: invisible yet always present. In large amounts, these small particles in the air can be harmful to our respiratory system. With the BRESSER PM 2.5 / PM 10 particulate meter, you can take control of monitoring the air quality. The European limits and WHO recommendations for air quality are regularly exceeded, especially in big cities. Heavy traffic, industry and agriculture significantly increase the concentration of particulate matter. To let you know when the air quality is poor, the particulate meter's wireless sensor takes precise measurements of two types of particulate matter that can be harmful to your health: Particles with a diameter of less than 10 μm (PM10) and less than 2.5 μm (PM2.5). The excellent sensor made by the renowned Swiss manufacturer Sensirion guarantees very precise measurement results. Thus, the particulate meter is also the perfect source of information for people with allergies in order to keep an eye on the pollen count. And you don't need to be an expert in order to determine whether the readings are within a healthy range: The air quality index shows you in 6 colour-coded levels whether the air is clean. Historical air quality data The damage that air pollution does to our health doesn't happen overnight. The particulate matter meter therefore records a range of historical readings, including the maximum readings from the past hour and 24 hours, and the overall historical maximum, to give you better idea of trends in the air quality. To view the current reading - regardless of the measurement interval settings - simply press the button on the sensor. The device also features a high alarm function: simply configure your desired limit for particulate matter and the alarm will sound when the limit is reached. If you normally measure the air quality indoors, but want to know whether the air is clean before you spend a sunny day in the garden, you can use the wireless sensor. The wireless sensor can also be used individually and shows you the particulate matter readings on the built-in display. Armed with this sensor, you can measure particulate matter both indoors and outdoors. Also ideal for travelling! Particulate matter meter with fresh air function Good air quality is about much more than clean air. A good indoor climate is also essential for our wellbeing. For this reason, the particulate matter meter also features a built-in thermo-hygrometer so that you can monitor your indoor climate in more detail. If you have mould stains in your bathroom or the air in your child's bedroom is too dry when you turn the heating on, you can take preventive measures by referring to the indoor temperature and humidity readings on the base station. What's more, if you put the air quality meter in your bedroom, it can also double up as an alarm. Simply set the time at which you want to get up and enjoy your well-earned sleep until the alarm goes off. If you want a few extra minutes in bed, you can press the snooze button to silence the alarm for 5 minutes. Monitor your air quality - with the BRESSER PM 2.5 / PM 10 particulate meter.

Simply set up and explore the Moon, Venus and co. straight away: With the BRESSER Stellar 60/800 AZ lens telescope, getting started in sky observation is quick and easy. The complete set already contains the necessary equipment for your new hobby: the astronomical lens telescope with 60 mm aperture and 800 mm focal length, the azimuthal mount, the tripod and extensive accessories for your voyage of discovery through the solar system. The beginner's telescope is very easy to use and therefore ideal for getting children excited about astronomy. Well-tried classic for completely new impressions - the telescope Especially for beginners and children, this classic lens telescope - also known as an achromatic refractor of the Fraunhofer type - makes it easy to enjoy astronomical sights. The modern, precisely coated optics ensure good imaging properties. Another strength of the optics: the 60 mm aperture and the 800 mm focal length result in a very large focal ratio (ratio of the aperture to the focal length) of about 1 to 13.3 (F/13.3). The result: a very sharp image with good contrast. The long focal length also makes the telescope a specialist for lunar, solar and planetary observation. However, open star clusters and globular clusters are also guaranteed to amaze you when you look through the telescope. And how big do the celestial objects appear? With the aperture size, the starter telescope achieves a resolving power which lets you enjoy really sharp images at up to 120x magnification. Technically, this entry-level telescope is capable of more - theoretically up to 600x with the included accessories. But: with increasing magnification, the image sharpness can slowly decrease. Of course, not only the telescope plays a role when it comes to magnification. The air turbulence in the atmosphere (seeing conditions) also affects your view of the night sky. The foundation for your view into space - mount and tripod The telescope tube is held securely on the height-adjustable aluminium tripod with azimuthal mount. And this azimuthal mount has a great advantage: it is very easy to operate. Just like a common photo tripod, you simply swing the telescope manually to the left and right, up and down. Perfect for beginners in astronomy and children. But where to put the accessories? To keep them within easy reach, just place eyepieces, solar filter etc. on the storage plate between the tripod legs. All you need for a quick start in astronomy - the accessories For your fascinating view of the night sky, the telescope for beginners comes with lots of accessories. Among them you will find a LED-viewfinder, with which you can easily keep track of the sky. It is mounted parallel to the actual telescope and projects a red dot onto a small screen. When you look through the viewfinder, the red dot appears to float in front of the sky - right where your starter telescope aperture is pointing. This way, the finder helps you to align your optics precisely and locate celestial objects - before you then take a closer look through the magnification of the telescope. You determine how much magnification you get by choosing the eyepiece. You will see: The two eyepieces (4 mm, 20 mm) included in the set alone offer quite different perspectives on the beauties of our cosmos. For the most versatile views possible, the socket diameter of 1.25 inch (31.7 mm) also complies with an international, manufacturer-independent standard. So if you want to expand your astronomy set later, you will have a wide choice of models. You have found an astronomical highlight and want to see even more details? Then place the 3x Barlow-lens between the telescope and the eyepiece. It will triple the magnification. Meanwhile the included 90-degree star diagonal mirror lets you comfortably admire the night sky. Even though your entry-level telescope is pointed upwards, you don't have to lie down underneath to enjoy the view. Instead, you look in comfortably from the side. But it is not only at night that we can observe the beauty of outer space. During the day, our own Sun is the undisputed star in the sky. So attach the solar filter to the aperture of your beginner’s telescope and safely observe sunspots and granulation. CAUTION: Never point the telescope at the Sun without the solar filter! To capture and share your unforgettable moments in astronomy, take your very own snapshots with the smartphone adapter. Thus the very first step towards astrophotography is easily taken! Look forward to your complete astronomical starter package and a whole new view of the Sun, Moon and planets - with the BRESSER Stellar 60/800 AZ lens telescope.
