PCE Instruments Carbon Dioxide Meter with CO2 Monitoring and Alarm System (PCE-WMM 50)
PCE Instruments Carbon Dioxide Meter (PCE-WMM 50) is a fixed wall-mounted CO2 detection system designed for monitoring carbon dioxide concentrations in indoor environments. With a built-in temperature sensor and adjustable alarm settings, this device ensures safety in workplaces where CO2 exposure is a risk.
The CO2 meter features a two-part system: a sensor unit and a remote display unit, allowing safe monitoring outside of hazardous zones. The device includes an alarm-activated potential-free contact, enabling the activation of ventilation or other safety measures when carbon dioxide levels exceed set thresholds.
