R718PA4
Hydrogen sulphide is toxic at low concentrations and often present around drainage and waste; the R718PA4 measures H2S from 0 to 100 ppm with resolution below 0.1 ppm and accuracy within 2% of range, responding in 30 seconds or less. The electrochemical gas cell (rated for more than two years in air) connects over RS485 to a LoRaWAN main unit powered from a 12 V DC adapter, rated IP65 and fitted with a magnetic base. Applications include sewage pumping stations and wastewater plant, waste-handling and recycling facilities, and confined-space areas such as pits and plant rooms where gas can accumulate.

Requires a LoRaWAN Gateway
R718PA4 sends its data over LoRaWAN, so it needs a LoRaWAN Gateway in range. Works with any LoRaWAN Gateway, such as the UG65. If you already have a Gateway on site, you can skip this.
