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...
Electrical conductivity (EC) serves as a core indicator reflecting water purity in smart water management, aquaculture and industrial wastewater monitoring. With a wide variety of models available on the market, how can you make an accurate selection? Based on the technical documentation of mature all-in-one LoRaWAN EC transmitters, this article sorts out four core dimensions for model selection. ...
In today’s smart buildings, agricultural greenhouses and industrial facilities, maintaining optimal air quality is no longer a luxury but a necessity. Carbon dioxide (CO₂) levels directly impact human productivity, crop health and overall environmental safety. Therefore, selecting a reliable, high-precision sensor forms the cornerstone of any successful monitoring system. We are proud to introduce...
