breathalyser for sale

If you need to buy a breathalyser, here is a good quality breathalyser for sale! Before that, you can start with its type and characteristics to decide what kind of breathalyser to choose. It can be applied not only to traffic police road alcohol detection but also to many places:

  • It can be used in the identification of alcohol intoxication at work;
  • It can be used for the detection of alcohol intoxication in driving schools;
  • It can also be used in some countries’ airports for detecting passengers' alcohol intoxication.

What Is A Breathalyser?

A breathalyzer is a device that measures the level of alcohol in a person's breath. It may also be called a blood alcohol content (BAC) meter, breathalyzer test, or breathalyzer machine. The word "breathalyzer" comes from the word "breathalyze."

A breathalyzer is a device that measures the amount of alcohol (ethanol) in your breath. It does this by analyzing the chemical composition of your breath and comparing it to a set standard. When you breathe into the device, it measures how much ethanol (or other substances) is in your breath and displays this number on an LED screen.

The device has two parts:

An air sample. The breathalyzer draws samples of fresh air through a mouthpiece. The device then analyses that sample and determines the concentration of ethanol in your breath by comparing it to a set standard curve.

A sensor. The sensor contains an array of sensors that detect specific chemicals produced when ethanol reacts with other molecules present in your mouth or throat.

There Are Many Types Of Breathalysers Available In The Market:

There are many breathalysers for sale in the market, and they are divided into many categories, such as electronic breathalyzers and digital breathalyzers. If classified according to the sensor type of breathalyser, SZEEK divides these products into three categories: fuel cell sensor alcohol tester, semiconductor sensor alcohol tester, and MEMS technology sensor alcohol tester. The following is an introduction to these three breathalyzers one by one:

1. Fuel cell sensor breathalyser: the same model used by the traffic police

If you have seen the law enforcement process of the traffic police on the side of the road, you will find that the breathalyser they use is a fuel cell sensor. It is a very simple device with a small fuel cell that detects traces of alcohol in your breath.

It works by means of a fuel cell membrane, which is activated when alcohol enters it through your nose. This activates an electrical signal, which results in a pulse being sent to an external unit or computer.

2. Semiconductor sensor breathalyser: the most common solutions

The semiconductor sensor alcohol tester is a type of electronic breathalyser that uses semiconductor technology to detect alcohol in the human body. These devices have simple construction, easy operation, and high sensitivity.

3. MEMS technology sensor breathalyser: based on semiconductor technology

MEMS (Micro Electromechanical System) technology sensor breathalyser is an updated breathalyser based on semiconductor technology. MEMS means that microcircuits and micromechanics are integrated into a chip according to functional requirements, and the size of the chip is usually millimeters or microns.

This microstructured gas sensor using MEMS technology combines a heating element and a sensitive element. This breathalyser for sale optimizes the performance of the gas sensor, greatly improving the sensitivity, reliability, and consistency of the gas sensor.

To sum up, the first breathalyser for sale is the type chosen by many traffic police, which can provide highly sensitive detection results and is very convenient. MEMS technology sensor breathalyser for sale is a new technology based on semiconductor technology, and its sensitivity and other functions have very good performance.

The second semiconductor sensor breathalyser for sale is the most common solution, and many factories or driver inspections will choose this. Because it can provide accurate results at the same time, be more cost-effective.

What To Consider When Choosing A Breathalyser For Sale?

Choosing a breathalyser for sale can be an overwhelming task, given the different types and models available in the market. Here are some factors to consider when choosing a breathalyser for sale:


The accuracy of the breathalyser is the most critical factor to consider. Ensure that the device you choose has a high level of accuracy and is regularly calibrated to maintain accuracy.

Ease of use:

The breathalyser should be easy to use and understand. The device should have clear instructions on how to use it and should not require any special skills or knowledge.

For example, SZZEK's EK916 fuel cell sensor breathalyser for sale only takes 5 seconds to warm up and respond. So you can get accurate results faster.

Size and portability:

The size and portability of the breathalyser are also important factors to consider. If you plan to use the device while on the go or in different locations, a small and portable breathalyser may be the best option.

SZEEK's breathalyser for sale is lightweight and very portable.


Consider the features that the breathalyser offers, such as a backlit display or a memory function to store previous readings. Some breathalysers may also have additional features, such as a smartphone app to track readings.

If you plan to use the breathalyser for legal purposes, ensure that the device meets the legal requirements in your state or country.

Battery life:

Consider the battery life of the breathalyser. A device with a longer battery life will be more convenient to use and save you money in the long run.

SZEEK also has some breathalysers for sale with built-in 1000mah lithium-ion batteries. This can provide a longer period of use.

By considering these factors, you can choose a breathalyser that meets your needs and requirements, whether for personal or professional use.

What Is Calibration? How Often Should You Do A Calibration?

After talking about how to choose a breathalyser for sale, let's focus on the calibration of the breathalyser.

What is calibration?

Calibration is the process of adjusting a breathalyser to ensure that it is working correctly. The calibration should be done at least every six months and more often if required.

How often should I do a calibration for my breathalyser?

You should do a calibration for your breathalyser at least every six months. If you have had your breathalyser for less than six months, you can still do an initial calibration, but this should not be used as a basis for future calibrations.
