DealExtreme: Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " (Bateria 9V - G6F22)

Hello Skooter Blog readers. Today I talk about Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " (Bateria 9V - G6F22) (2.0″ LCD Distance Meter Measurer with Laser Pointer (1 x G6F22)) acquired on DealExtreme, whose buy here has been detailed in the Skooter Blog, so this article merely speak product.

The Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " is that sellers Brazilians are called digital tape, trena ultrassônica, trena a laser, electronic tape, ultrasonic distance meter, among others. With this equipment you can measure distances with some accuracy quickly. I think it does not replace a traditional tape measure when you need absolute confidence in the measures taken, or even as furniture and other objects, but it is much quicker as of rooms and areas enclosed by walls.

The operation of Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " is relatively simple to understand. It emits a series of ultrasonic pulses of short duration. These pulses propagate through the air, until they encounter an obstacle (a wall, for example), where they will rebound and return to the Ultrasonic Distance Meter, if it was properly aligned with the obstacle, and for that he has a bubble level. By measuring the time it takes the pulse to go through the obstacle and back (echo time) and the propagation velocity of the pulses in the air, the Ultrasonic Distance Meter can calculate distance using the famous formula of ice cream, that you learned in high school, S = S0 + V t, where S is the space (distance), S0 is the initial distance (in this case zero), In is the propagation velocity of an ultrasound pulse in air, which is somewhere around 340 m/s (meters per second), and t is the propagation time measured divided by two (remember that we measure time round, in other words, twice the propagation time from S0 to S).

If the measurement of Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " is performed with ultrasound, you may be wondering: where do you get the laser in this story? It serves only to guide the user, in other words, you see a red blip on the obstacle that is measuring, to make sure it pointed to the right place while making the measure. He has no influence insofar, you can even cover the output of the transmitter and the reading will be done the same way.

The instruction manual Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " is in Danish, filandês and Swedish. My knowledge of these languages ​​is just enough for me to have achieved at least distinguish which were the three tongues that were in this manual. But thankfully the operation of the device is quite simple and could deduct it completely in a few minutes. Describe it further.

The brand Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " é New Pro, that belongs to a company called Nomenta, Danish-Chinese company that produces a wide variety of electronics, Denmark apparently designing and manufacturing in China, which explains the language in the instruction manual. The model in question is the DM-105, which calculates distância, area and volume. Measurements can be made both in metric and in imperial.

The specifications, I managed to extract from the manual Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " can measure distances of at least 60cm (centimeters) and maximum 18m (meters). At the rear there is a specification of wavelength 650nm, which certainly is the wavelength of the red laser. There is also a rated power of <1mW, This also probably refers to the laser. You never know what is the frequency used by ultrasound, totally omitted in manual. It is powered by a common 9V battery (G6F22), and now comes with a copy of the same brand Tought, without mercury, manufactured in China.

And let the functioning of Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 ". He has 5 buttons. The ON / OFF button turns the equipment. The MODE button toggles between 4 functioning modes: measuring the distance in one step; measuring the distance in two stages (sums the two); that Medea area, sequentially taking measurements of length and width and make the multiplication; and the Medes volume, picking sequentially width, and making length and height multiplication. Measurements are given in meters (m), sqm (m²) and cubic meters (m³), or the equivalent in imperial. The RECALL button displays the intermediate measures of modes that take more than one measure. The button FT / M switch between imperial and metric system. Finally the central button R, yellow, is used to make measurements.

The performance of Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " it's good. He is very precise when used in optimal conditions. For optimum conditions, understand that it is perfectly aligned at 90 degrees to the surface where the pulses will reflect, flat surface such seja, and that there are no obstacles too close to the path where the pulses will pass, because that seems to influence the route of pulses and disrupt the measurements. He seems to be perfect for those looking / evaluating a property and need to quickly take measurements of rooms, and other situations in which you must take action quickly.

A video to better illustrate the operation of Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " is shown below. Note, however, that the measures appear not correspond to reality, not because I was careful to point it at the wall at the correct angle.

And I'm ending here the article on Ultrasonic Distance Meter with Laser Pointer and LCD 2.0 " (Bateria 9V - G6F22) (2.0″ LCD Distance Meter Measurer with Laser Pointer (1 x G6F22)). If you also want to shop in DealExtreme, directly from Hong Kong, click here, good shopping.
