New arrival portable single gas detector adopts 1.54 inch TFT LCD color screen display. The operation interface is beautiful and generous, it supports Chinese and English language. When the concentration exceeds the preset value, the instrument will make sound, light and vibration alarm. It has mass data storage and can store 3,000 alarm records and 990,000 real-time records.
This portable single gas detectors with TWA and STEL functions provide real-time monitoring of gas concentrations and trigger alarms if levels exceed the prescribed limits. This makes it easier for workers to detect hazards quickly, take corrective action promptly, and avoid serious health risks.
Portable gas detectors are essential for workers who are exposed to potential gas hazards in their workplaces. The time-weighted average (TWA) and short-term exposure limit (STEL) functions in these devices play a critical role in ensuring workers' safety.
TWA measures the average concentration of a gas over a specified period and compares it to the allowable exposure limit. If the TWA limit is exceeded, the device alerts the user, and corrective action can be taken to reduce exposure. The TWA function is particularly useful for monitoring prolonged exposure to gases like carbon monoxide and hydrogen sulfide, which can have serious health implications.
The STEL function, on the other hand, measures the concentration of a gas over a short period, typically 15 minutes. It is designed to detect sudden or intermittent exposure to high levels of gas, which could be hazardous to workers' health. The STEL function is ideal for toxic gases like ammonia and chlorine, which can cause respiratory distress and other health problems.
gas detectors are also widely used in the mining industry. Workers in underground mines are often exposed to gases such as methane, carbon dioxide, and carbon monoxide, which can be deadly. Single gas detectors are used to monitor the levels of these gases and ensure the safety of workers.
In the manufacturing industry, single gas detectors are used to monitor the emissions of hazardous gases from production processes. This helps to ensure compliance with environmental regulations and protects workers from exposure to harmful gases.
Another important application of single gas detectors is in the oil and gas industry. They are used in oil refineries and drilling sites to monitor the levels of toxic gases and ensure the safety of workers. These detectors are also used in chemical plants, where there is a risk of exposure to hazardous gases such as chlorine and ammonia.
