Fixed Gas Detector-PQ Series

The use of different sensor technologies, such as PID, Pellistor, Electrochemical, Infrared, and Semiconductor, allows the PQ Series to provide accurate and reliable measurements for various types of gases.

The ability to measure gases in different ranges, from LEL to ppb, also makes it versatile and useful for various applications.

The classification of the PQ Series as PQD (With Display) and PQN (Without Display) shows that Prosense understands the diverse needs of its customers and provides options to choose from based on their requirements. A display can be helpful in some situations, while in others, it may not be necessary.

Overall, it appears that Prosense “”PQ”” Series fixed gas detectors are well designed and suitable for harsh environmental conditions, making them a reliable solution for a variety of industries.
