Duct air velocity transmitters are critical equipment for acquiring airflow data in ventilation, environmental protection and industrial exhaust monitoring projects. Improper selection may cause measurement deviations, system incompatibility, or even equipment damage. The following outlines key selection criteria across five dimensions to support sound decision-making. 1. Determine Measured Medium...
Phosphine (PH₃) is a colourless, pungent and highly toxic gas, as well as a strong reducing agent. Its toxic threshold limit value (TVL) is below 0.3 ppm. Any leakage can cause severe damage to the central nervous system. For this reason, real-time phosphine monitoring is critical for industrial safety, agricultural production and environmental protection. With numerous PH₃ sensors available on th...
Phosphine (PH₃) detection is increasingly common in industrial safety, agricultural production and environmental monitoring. With a wide variety of gas sensors available on the market, how to select a suitable RS485 PH₃ sensor? The key points below can serve as your reference. 1. Measuring Range and Resolution Clarify the on-site PH₃ concentration range before selection. This sensor adopts an elec...
Online multi-parameter water quality sensors reduce installation points and wiring costs. However, selection should not only focus on "how many parameters can be measured". Taking the ZW-MPS-PR online multi-parameter self-cleaning sensor as an example, follow the 6 steps below to avoid selection errors effectively. 1. Define mandatory monitoring parameters The ZW-MPS-PR can integrate dissolved oxy...
