Portable Gas Monitor

A portable gas monitor is an indispensable tool in modern industry, as well as in environmental protection and home safety. This compact yet powerful device monitors harmful airborne gases such as carbon monoxide, sulfur dioxide, and methane in real time to ensure a safe operating environment. Whether it is used on the factory floor, construction site, or in the home, the convenient gas detector provides accurate and fast gas detection to help users identify potential hazards promptly. With the advancement of technology, there are many high-quality portable gas detectors on the market, which are not only easy to operate and accurate, but also equipped with various intelligent functions to provide users with more comprehensive safety protection, Tool online shop, as a high-quality supplier, is committed to providing users with high-quality gas monitors to satisfy all kinds of needs.

Portable gas detection technology can be used for a variety of gas detection, accurately making early warning of hidden danger detection technology development is rapidly changing, in the accident precursor inspection, elimination of the application is more and more extensive, and its direction of development is miniaturization and automation, to achieve long-term monitoring. Portable gas tester development makes the leakage process can be detected in the early stage, certain disasters are difficult to avoid. How to effectively inhibit and monitor early warning, for accidents that have occurred, how to make reasonable use of high-tech means to implement effective control of the accident, reduce casualties and property losses, is the key technology of production safety needs to focus on solving the real problem.

Through the study of the physical and chemical properties of the accident in the early stage, gas detection and monitoring can effectively carry out pre-disaster suppression, so that accidents that may become disasters are controlled in advance while protecting personal safety. From passive rescue technology to a new generation of active prevention and control technology change the key is intelligent monitoring technology at the core.

Portable gas detectors are widely used in industrial safety monitoring, indoor air quality testing, hazardous substances detection, and environmental protection monitoring. Aiming at the key links in the process of disaster conception, occurrence, and development, and destroying its chain development chain, it is an important link in the technical system of preventing and controlling safety accidents.

Portable gas tester can be divided into diffusion type and pump suction type through its sampling principle. The so-called diffusion type is the probe is placed in the detection of gas in the danger zone, by the space to be determined by the gas diffusion to the probe, and the alarm is placed in the monitoring room, for instructions and alarms. The pump suction type is to be measured gas pump suction detection probe, suction pump, and gas built-in detector are located together, is the detector is located in the hazardous location of the gas to be measured, to detect the implementation of the indication and alarm function.

Portable Gas Monitor Design

Portable gas detectors are often used in harsh environments and are designed to be waterproof and dustproof. Usually, the protection level is from IP65 to IP67, which is the common industrial protection level in the world, and the last two digits indicate the level of dustproof and waterproof.

IP65 means that the instrument is impervious to dust and water; IP67 means that the instrument is impervious to dust and water. The protection level of the portable instrument depends on the sampling principle, the diffusion sampling level is higher, IP67, pump suction products due to the gas inhalation sampling at the same time can not be completely waterproof, most can only do IP65. gas detector instrument itself is also very important to prevent the design fall, usually 3 meters, 6 meters, and 8 meters. If the instrument can be dropped from a height of 3 meters onto a concrete floor and still function normally, it will be able to withstand normal environmental impacts, but of course, 8 meters is the best.

1. Simple Operation: Considering the operation's simplicity, a single gas detector usually has only one button, and a multi-gas detector mostly has three buttons. For the sake of workers' practical operation, the buttons are designed to be larger and can be easily operated with gloves. The readability of the screen is also an important factor, the display size is wide for the best, and the display technology if the use of LCD, is more flexible and clear than the LED.
2. Long-life Sensor: The sensor is the most important and expensive component of a portable gas detector. The accuracy of the gas detector depends on the sensitivity of the sensor. Sensor life is usually 1 to 2 years. Depending on the detection principle, sensors are classified as semiconductor, electrochemical, catalytic combustion, photoionization (PID), and infrared sensors. A fixed type of sensor is generally used for the different gases to be measured. Good sensors respond quickly, have sensitive readings, strong anti-interference ability, good repeatability, saving calibration gas, and sensor lifetime directly related to the cost of use.
3. Long Operating Time: The operating time of a portable gas detector depends on the operating time of the battery. There are dry batteries or rechargeable batteries, and there are also two available instruments that complement each other. The longer operating time on the market today is 16 hours and 24 hours for two shifts of workers. Depending on the frequency and duration of the alarm, the actual application time may vary.
4. Perfect Alarm System: Portable gas monitors on the market today generally have audible, alarm light, and vibration alarms. Special attention should be paid to not only the detection distance and decibel value (e.g. at 30cm>95Db) but also the sound penetration when confirming the sound alarm. There is also a fall alarm function, if an operator falls and loses consciousness for more than 20 seconds, the instrument will automatically issue an alarm, and if it continues for another 10 seconds, it will evolve into a high alarm. There is also an immediate alarm function, if the operator perceives an emergency at the scene, he can manually touch the button through the instrument to send an alarm to the surrounding personnel.

Precautions

• Pay attention to the measurement range of the portable gas detector you are using: Any gas tester has a fixed detection range, and the measurement can only be completed within that range, otherwise the measured results will be much lower than the value of your environment. In addition, a long time in the over-range measurement will cause damage to the sensor, so that later in the measurement range can not get the correct results.
• Pay attention to the service life of the sensor in the gas detector used: Gas detectors have a service life limit, and portable gas detectors are no exception, even if they are not used frequently, there will still be an aging phenomenon. In general, in the portable gas detector, photoionization detector life is the longest, for about four years, LEL sensor life is second, and can be used for more than three years; electrochemical specific gas sensor life is relatively short, generally in one to two years. Oxygen sensors will only last about a year. Therefore, it is important to look at the manual before use, to use the sensor within its expiry date, and if it is found to be out of date, it needs to be replaced immediately.
