Abstract
Description
Technical Field
[0001] This utility model relates to the field of formaldehyde production environment monitoring technology, specifically a monitoring device for formaldehyde production workshops. Background Technology
[0002] Formaldehyde monitoring equipment in formaldehyde production workshops is used to monitor formaldehyde concentration in the workshop in real time, aiming to ensure production safety and worker health. The equipment collects formaldehyde concentration data in the air through sensors, converts the collected analog signals into digital signals, and after data processing and analysis, transmits the data to the monitoring system via wired or wireless communication.
[0003] Formaldehyde levels in a production workshop are affected by factors such as airflow, temperature gradients, and humidity, resulting in varying monitoring data at different heights and locations within the workshop. This means that data from a single monitoring point cannot reflect data from all areas of the workshop. Installing multiple monitoring devices not only increases costs but also maintenance costs. To address these issues, this invention provides a formaldehyde monitoring device for formaldehyde production workshops. Utility Model Content
