PCE Instruments PCE-WMM 50-ICA Gas Test Instrument for CO2 with 2 configurable alarm thresholds and 4-digit digital display
(Incl. Tax: €709.92)
The PCE-WMM 50-ICA CO2 gas transducer is an economical device with an integrated alarm for detecting carbon dioxide (CO2), ideal for protecting against colourless and odourless gases that are hazardous to health. It is mainly used in sectors such as the food industry, metallurgy, chemistry and waste management. Consisting of two parts, the transducer is placed in the hazardous areas, while the control unit is located outside. The system offers two adjustable alarm levels and triggers an optical and acoustic warning when the measured value exceeds a preset threshold.
The CO2 gas transmitter PCE-WMM 50-ICA is equipped with a 4-digit digital display and 4 LEDs, allowing constant visual monitoring of gas concentrations. The potential-free switching output is easy to access and allows other alarm devices to be activated, suction motors to be turned on, or machinery to be stopped. The CO2 gas transmitter PCE-WMM 50 can be easily installed on a wall. Carbon dioxide is harmful to the human body, even in small doses. Even at concentrations of 0.3%, it can be detrimental. If the value reaches 5%, it can cause headaches and dizziness. Values around or above 8% can cause fainting or even death.
