Typical applications

The E2639-VOC(C7H8) detector is intended for monitoring toluene in environments such as paint shops, printing works, chemical and pharmaceutical facilities, paint and thinner stores, vehicle repair workshops, and other enclosed spaces where volatile organic compounds may accumulate.

Toluene (C7H8)

Toluene is a volatile organic compound that readily evaporates into the air and can accumulate in enclosed spaces to dangerous levels. Although it has a characteristic odour, it cannot be relied upon as a warning sign, because the sense of smell quickly adapts with repeated exposure and stops detecting it. Exposure may lead to headaches, nausea, dizziness, or impaired concentration, and at higher concentrations or with prolonged exposure there is a risk of serious damage to the nervous system, liver, and kidneys.

Smart communication – ideal for fire alarm systems

The E2639 detector combines the advantages of an autonomous safety device and an intelligent communication node. It is designed for seamless integration with fire alarm systems (EPS) and offers a wide range of outputs for comprehensive control:

• Autonomy: 3× volt-free SPDT relays for direct control of equipment or safe system shutdown.
• Connectivity: Dual RS485 Modbus RTU interface for digital export of measured data in real time to a higher-level system (BMS).
• Control: 2× 4–20 mA analogue outputs intended for precise control of the ventilation frequency inverter.

WiFi calibration from any smart device

Compared to the standard version, the E2639-WF has an integrated WiFi module that turns calibration and configuration into a matter of minutes – without tools and without removing the cover. The access point is activated using a magnetic key, and the configuration interface opens in the browser of a phone or tablet, with no need to download any app. The interface is password-protected with separate access levels for end users and integrators, so each user works only within their own section of the settings.
