The Ritmix RAT 310 compact breathalyzer, the reviews of which we will consider later, is a simple and inexpensive device designed for personal use by the driver. With it, you can check your own condition after drinking alcohol. This kind of analyzer 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 Ritmix RAT 310 breathalyzer are very mixed. 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 blowing the air into the test 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 recorded, and the data is displayed on a digital monitor.
The advantages of this device include compact dimensions (120/70/30 millimeters). The ergonomic shape allows you to comfortably hold the analyzer in your hand. In appearance, it is an elongated handle with a mouthpiece integrated on the side. Also in the design of the device includes a liquid crystal display, power key, battery compartment, chain with a ring. Using the last element, the device can be fastened to the keys as a key fob.
Functioning
Reviews on the Ritmix RAT 310 breathalyzer confirm that it is able to show results in ppm and YOU. For example, 0.05 BAC indicates the presence of 0.05 ethanol in 100 milliliters of blood of the test individual. The device can also show not only digital results, but also special marks Caution and Danger. They indicate that the indicators are in the range from 0.2 - 0.5 ppm or exceed the last value, respectively. The option against cheating in the specified series is not provided. In case of insufficient inhalation or exhalation of the tested person, the device will show an incorrect result.
The total measuring 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 digit greater than zero, this tells the driver that you should not drive. The error, according to the manufacturer, is no more than 0.01 YOU in two directions. A significant minus of the device is the lack of a battery; a pair of AAA configuration batteries is used as power elements.
Features
The instructions for the Ritmix RAT 310 breathalyzer indicate one point - 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 much time. The testing process itself lasts about 10 seconds after inhalation. Since the device has the option of automatic shutdown, it is triggered 10-15 seconds after the results of the verification are displayed on the screen. The operating temperature range is +5 to +40 degrees ° C.
Ritmix RAT 310 breathalyzer: how to use?
Instructions for use are given below:
- It is advisable to conduct 2-3 tests, and from them choose the average value.
- It is not effective to use the tester in conditions of a significant amount of dust in the air or in strong winds.
- It is not allowed to subject 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 prolonged exposure to frost leads to its failure.
- If the device gives inconsistent information, it is necessary to warm it up, hold the sensor under a stream of warm air (hairdryer).
Beginning of work
The operation process of the Ritmix RAT 310 keychain starts in any case with warming up. To do this, hold down the Power button for one second. After a beep and turning on the monitor, you can continue the action. In preparation for testing, Warm will appear on the display. This means that the analyzer has entered the 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 prolonged storage of the tester. Blowing directly into the mouthpiece follows after the Blow value appears on the monitor. Preliminarily, you should inhale well, since it will take at least ten seconds to blow into the mouthpiece. The operation is considered to be completed after a sound notification.
Maintenance and care
According to reviews and instructions for the Ritmix RAT 310 keychain, if testing is carried out immediately after drinking alcohol, you must wait 20-25 minutes when the concentration of ethanol in the blood becomes maximum. A break of at least three minutes should be taken between the first and second examinations. Before testing, it is not recommended to eat and smoke for at least 20 minutes.
The mouthpiece is cleaned with a dry cloth or a clean cloth, without the use of chemicals. In addition, no liquid must be poured into the analyzer hole. Even the ingress of smoke from a cigarette or saliva inside the sensor will lead to its malfunction. Any formulations with a pungent odor, such as acetone, deodorant, alcohol, are not recommended to be stored next to the appliance.
It is worth noting that the apparatus in question is not particularly accurate in determining the selectivity of alcohol in the blood. Therefore, a diet with a predominance of low-carbohydrate foods, diabetes mellitus, and other factors contributing to an increase in the ketone content in exhaled air can lead to a distortion of the final result.

As noted by users, this analyzer is affordable, has a beautiful original design, and is easy to use. It can be used as a keyring, it is easy to maintain and care. 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, showing per mille after eating specific foods such as mandarin or kefir.
In conclusion
The Ritmix RAT 310 Individual Breathalyzer (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 drive, if any value above the zero mark appears on the display, it is better to call a taxi or walk.
