The compact breathalyzer Ritmix RAT 310, reviews of which we will consider below, is a simple and inexpensive device intended for personal use by the driver. With it, you can check your own state after drinking alcohol. This kind of analyzers is not used by government services. It is real to buy a product in online stores without any permits at an affordable price. Consider its characteristics and features.
Description
Reviews about the breathalyzer Ritmix RAT 310 are very ambiguous. We will consider all its pros and cons a little later, and now we will study the design and principle of operation. The device is designed to detect residual vapors of ethyl inclusions in human breath. It is equipped with a semiconductor sensor, which is a crystal with a porous substance. After the test subject blows air into a special hole, the alcohol molecules are fixed by the sensor, passing through its filler. Under this influence, the electrical conductivity changes. As a result, the change is fixed, anddata is displayed on a digital monitor.
The advantages of this device include compact dimensions (120/70/30 millimeters). Ergonomic shape allows you to comfortably hold the analyzer in your hand. In appearance, it is an elongated handle with a mouthpiece built into the side. The design of the device also includes a liquid crystal display, a power key, a battery compartment, a chain with a ring. Using the last element, the device can be fastened to keys like a key fob.
Operation
Reviews about the breathalyzer Ritmix RAT 310 confirm that it is able to show results in ppm and BAC. For example, 0.05 BAC indicates the presence of 0.05 ethanol in 100 milliliters of the tested individual's blood. The device can also show not only digital results, but also special Caution and Danger marks. They indicate that the indicators are in the range from 0.2 - 0.5 ppm or exceed the latter value, respectively. The option against deception in the specified series is not provided. If the test person does not inhale or exhale enough, the device will show an incorrect result.
The total measurement limit does not exceed 1.9 ppm. This means that this analyzer simply will not show a large concentration. But, this is not particularly important. If the tester displays a number greater than zero, this tells the driver that it is not worth getting behind the wheel. The error, according to the manufacturer, is no more than 0.01 VAC in two directions. The main disadvantage of the device is the absence of a battery, ina pair of AAA batteries is used as the power supply elements.
Features
In the instructions for the breathalyzer Ritmix RAT 310, one point is noted - it takes up to ten seconds to start and warm up the analyzer, provided that the batteries are new. Users claim that in fact, adaptation takes twice as long. The testing process itself lasts about 10 seconds after inhalation. Since the device has an automatic shutdown option, it works 10-15 seconds after the test results are displayed on the screen. The operating temperature range is from +5 to +40 degrees °C.
Alcotester Ritmix RAT 310: how to use?
Recommendations for using the device are given below:
- It is advisable to conduct 2-3 samples, and choose the average value from them.
- The use of the tester is not effective in conditions of a significant amount of dust in the air or in strong wind.
- It is not allowed to expose the device to shocks and other mechanical influences.
- Store the unit in a dry place at the temperature specified in the instructions. It is noted that a long stay of the product in the cold leads to its failure.
- If the device gives inconsistent information, it must be warmed up, hold the sensor under a stream of warm air (hair dryer).
Getting Started
In any case, the operation process of the Ritmix RAT 310 breathalyzer-trinket begins with warming up. For thishold down the Power button for one second. After a beep and the monitor is turned on, you can continue the action. During the test preparation phase, Warm will appear on the display. This means that the analyzer has entered test preparation mode. Then a countdown will appear on the screen (from 10 to 0).
The new apparatus is warmed up and launched several times. A similar manipulation is also carried out after long-term storage of the tester. Blow directly into the mouthpiece after the Blow value appears on the monitor. You should first inhale well, since you will have to blow into the mouthpiece for at least ten seconds. The operation is considered completed after the sound notification.
Maintenance and care
As evidenced by the reviews and instructions for the breathalyzer-trinket Ritmix RAT 310, if testing is carried out immediately after drinking alcohol, it is necessary to wait 20-25 minutes when the concentration of ethanol in the blood reaches its maximum. There should be a break of at least three minutes between the first and second examinations. It is not recommended to eat or smoke for at least 20 minutes before the test.
The mouthpiece is cleaned with a dry cloth or a clean cloth, without the use of chemicals. In addition, no liquid should be poured into the analyzer opening. Even if smoke from a cigarette or saliva gets inside the sensor, it will malfunction. Any products with a strong smell, such as acetone, deodorant, alcohol, are not recommended to be stored near the device.
It is worth noting thatthe apparatus in question is not particularly accurate in determining the selectivity of alcohol in the blood. Therefore, a diet with a predominance of low-carb foods, diabetes mellitus, and other factors that increase the ketone content in the exhaled air can lead to a distortion of the final result.
Reviews on the Ritmix RAT 310 keychain breathalyzer
As users note, this analyzer is affordable, has a beautiful original design, and is easy to use. It can be used as a keychain and is easy to maintain and maintain. Some consumers note that the device is quite suitable as a gift. The disadvantages include the lack of a battery, as well as the inability to work at sub-zero temperatures. In addition, the tester may be mistaken when showing ppm after eating specific products such as tangerine or kefir.
Finally
Individual breathalyzer Ritmix RAT 310 (reviews confirm this) is one of the most popular analyzers in its segment. Despite the fact that the accuracy of the device leaves much to be desired, it is quite suitable for individual use, since its results do not have any legal force. The driver simply should not get behind the wheel, if the display shows any value above zero, it is better to call a taxi or walk.
