Can an ammonia detector be used to detect monomethylamine?
Thread Content
Flammable and toxic sensors used in enterprises present two issues: 1. There are many types of flammable gases, but the design institutes use a unified term of \"flammable gas detector\", with the model designation also being \"flammable gas\" – is this acceptable? 2. Can a detector designed to detect NH3 be used to detect methylamine gas? Thank you!
1. Combustible gas detectors are generally capable of detecting various types of combustible gases, but different types of these gases may exhibit differences in terms of the detector’s sensitivity and response time. Therefore, it is best to select the appropriate type of combustible gas detector based on the actual conditions, in order to ensure accurate and reliable detection results. 2. The NH3 detector is primarily used to detect ammonia concentrations; since dimethylamine and ammonia have different molecular structures, the NH3 detector cannot directly detect dimethylamine gas. To detect methylamine gas, a specialized methylamine gas detector is required. .
1. There are many types of combustible gases, but the design institutes uniformly use \"combustible gas detectors\"; the type indicated on the nameplate is \"combustible gas\". Is this acceptable? This is acceptable
1. The detectors designed by the design institute should comply with **standards or industry specifications, and be capable of detecting various common combustible gases (such as methane, ethane, propane, etc.). However, when in use, it is still necessary to select the appropriate probe based on the specific circumstances, and the type of probe used should be indicated on the detector’s nameplate. 2. Under normal circumstances, detectors designed for detecting NH3 cannot be used to detect methylamine gas. Since different gases have different chemical properties and characteristics, appropriate detectors must be used for their detection. If it is necessary to detect methylamine gas, a dedicated methylamine gas detector should be used. The above suggestions are for reference only
Now, any new construction, renovation, or expansion project must be designed by a qualified design institute; for projects that are classified as of high importance or significance, additional Class A qualifications are required. So why are there still so many flaws identified during expert inspections? Who should be approached in such cases?

For toxic substances, it’s best to make corresponding arrangements; the primary and secondary alarm thresholds vary depending on the medium. The hassle caused by having to check the nameplate is not worth it—it’s better to simply replace the detector
