Product Overview

Rapid Solutions for Gas Detection Instruments and System Integration

The Stox by German EC Sense is an intelligent gas sensor detector, which simultaneously outputs two-wire 4-20mA and RS485 Modbus-RTU signals.

Select 4-20mA or RS485 signals for communication as per requirement.

Utilize high availabilityRugged solid polymer electrochemical gas detection technology, intelligent algorithm design.

Combining gas and humidity & temperature monitoring for industrial safety needs in a modular integrated design.

This sensor probe is suitable for gas detection in both indoor and outdoor environments, while also monitoring temperature and humidity inside the Stox housing, providing users with real-time dynamic data of the measured environment.

Due to the close relationship between the chemical properties and the state of motion of gases and temperature and humidity,Relevance, the performance of the sensor is also closely related to the temperature and humidity conditions.

This design provides professional data support for users to analyze and interpret measurement results.Only RS485 output with temperature and humidity signal.

Intelligent dual assessment of gas sensor performance and lifespan, regularly outputting the lifespan and performance indicators of the sensor, regardless of the presence or absence of the measured gas.

Alert signals are promptly outputted, making this feature a fundamental basis for judgment and analysis in intelligent product design.Data based on

Ensure product safety and reliability. Users can obtain information on whether the sensor is operating normally, failing, requiring maintenance, or replacement through output signals or RS485 commands.

Each Stox gas sensor detector is professionally gas calibrated, ready for direct use by the user.

Calibration information is stored in the Flash chip. For users who require a second calibration, the calibration software provided by EC Sense can be utilized.

Calibrate through RS485 output, or directly calibrate the 4-20mA signal.

The Stox series gas sensor detectors utilize standard 4-20mA or RS485 Modbus-RTU industrial signal protocols.

Easier to quickly build your own monitoring instruments and systems, or connect to display instruments, DCS, PLC, and other systems.

Principle of Testing

This intelligent gas sensor detector is a durable product, converting the original weak current signal of the sensor,

Converted through digital circuitry to standard 4-20mA or RS485 Modbus-RTU output. Solid-state polymer electrochemical sensing technology.

This technique is an innovation in the field of electrochemical detection, based on the principle of electrochemical catalytic reactions.

Detect electrical reaction output signals of various gases, accurately measuring gas concentrations through signal quantity.

Sensor is composed of three catalytic electrodes and a solid-state electrolyte.Quality and gas diffusion holes composition. Gas reaches the working electrode of the sensor through the diffusion holes.

Electrochemical redox reactions occur on the porous microsurface of the electrode, the solid electrolyte conducts electron transfer, outputs a current signal, and the magnitude of the current signal is

Can characterize gas concentrations.
