A sound level meter is an instrument used to measure the intensity of sound, and it works based on the principle of pressure wave propagation and energy transfer of sound. Sound is a pressure wave caused by the vibration of air molecules, and these pressure waves propagate through the air and eventually reach the human ear. A sound level meter evaluates the intensity of sound by measuring these pressure waves of sound and converting them into units of sound intensity (decibels) that can be perceived by the human ear. If a sound level meter malfunctions, it may affect its measurement accuracy and function. Here are some common sound level meter malfunctions and how to troubleshoot them.

The sound level meter also called the noise meter, is an instrument used to measure the sound pressure level or sound level of sound, is the most basic and most commonly used instrument in acoustic measurements, with the development of the national economy and the improvement of people's material and cultural living standards, noise census and environmental protection work carried out comprehensively.  The machine manufacturing industry has taken the noise as one of the important quality indicators of the product, auditoriums and gymnasiums, and other buildings do not only require the shape of the beautiful but also the pursuit of acoustics, all of which makes the sound level meter is more and more widely used. The buildings such as auditoriums and gymnasiums not only require beautiful shapes but also pursue acoustic effects, which make the application of sound level meters more and more widely.

A water leak detector is a device used to monitor and detect water leaks and leaks in a building, facility, or system. They are widely used in homes, commercial buildings, industrial facilities, and other locations and are designed to detect potential water leaks early enough to take the necessary steps to prevent or minimize damage.  According to its working principle, installation location, and functional characteristics, sisco store introduces you to several types of water leak detectors that can be categorized.

A water leak detector is a device used to detect water leaks or flooding and is commonly used in waterproofing and security applications such as domestic, commercial, and industrial environments. When choosing a water leak detector, there are some key factors to consider to ensure that the device you choose is suitable for your needs and environment. Here are some key points to consider when choosing a water leak detector.

A pH meter is an instrument used to test the acidity or alkalinity of a solution by measuring the active concentration of hydrogen ions (H+) in an aqueous solution to determine its acidity or alkalinity. A pH meter is a precision electrochemical instrument used to measure the concentration of hydrogen ions in dissolved liquids. It utilizes the physics of the response of an electrode to H+ ions at different temperatures and pressures. The value measured by a pH meter is called the "pH value", which usually ranges from 0 to 14, with smaller values indicating a more acidic pH, and larger values indicating a more alkaline pH.

A gas detector is an instrument that detects the concentration of a gas. The gas detector is suitable for the existence of combustible or toxic gases in dangerous places and can be long-term continuous detection of the measured gas in the air within the lower explosive limit of the content.  It can be widely used in gas, petrochemical, metallurgy, iron and steel, coking, electric power, and other industries where combustible or toxic gases exist, and is an ideal monitoring instrument for protecting property and personal safety. Before we use the gas detector, how should be installed to make it play a better performance and operation, the next will be sisco.com for you to answer the question.

A pH meter is a scientific instrument used to measure the activity of hydrogen ions in a water-based solution and express the acidity or alkalinity of the solution in terms of pH. The potential difference is related to the acidity or pH of the solution. Testing pH by means of a pH meter has a wide range of applications, from laboratory experiments to quality control. Acid meters, also known as pH meters, are relatively common instruments and equipment used in laboratories to precisely measure the acidity and alkalinity values of liquid media (e.g., Mettler pH meters). So do you know how to use a pH meter correctly? The sisco store will now share with you the correct way to use the acid meter.

We live in a world that needs gas detectors. Chemical production such as gas, LPG, natural gas units and oil and gas fields, mining detection and alarms as well as life cannot do without it. They can detect the presence of many gases that we can't feel and perform many other tasks that make our lives easier and less stressful. In this article, the sisco store will introduce the classification and application of gas detectors in detail.

In recent years, frequent fires have claimed numerous lives. As technology continues to advance, more and more new homes are being built with smoke alarm systems. The safety of the family home has always been our main concern, so smoke detectors are used in interconnections to help prevent fires from occurring. Smoke detectors are an important tool to effectively prevent fire, the user in the use of smoke detectors, smoke detectors will occur false alarms, and the user does not know how to solve them. Next, the sisco store to teach you how to use the smoke detector.

Accidental gas leakage and smoke overflow can pose a great threat to our property, environment, and life, smoke detectors and gas detectors are more common in our life and bring a lot of convenience to our life, for maintaining our safety play a very good role in ensuring that we improve its process.  Understanding the difference between smoke detectors and gas detectors is very important for the correct selection of the desired detector, you can effectively understand the performance of the detector and improve the service life of the detector.
