CO Sensor 500 PPM Range 0.1 PPM Resolution
CO Sensor (0.1 PPM Resolution)
Qsafe CO sensor uses electrochemical technology using the most effective means of monitoring CO gas. The co sensor collects a sample of air, and when it reaches the working electrode, a chemical reaction occurs, producing electricity via oxidation or reduction. The quantity of power generated is proportional to the amount of carbon monoxide in the sample.
- Electrochemical technology-based
- Range up to 500 PPM
- In compliance with ROHS
- 20mm x 20mm dimension
CO Sensor (1 PPB Resolution)
Qsafe’s CO sensor comes in a variety of sizes and formats, including PPM and PPB. The sensor may be used in both stationary and portable detecting equipment, as well as EMS and network applications. It uses electrochemical technology to function. The sensor adheres to the RoHS directive (Restriction of Hazardous Substances).

What are the unique features of CO Sensor?
Compact
Easy to lodge in any device/ instrument due to its small size and ultra-thin packaging. The sensor is ideal for both handheld devices and real-time outdoor monitoring.
Durable
The operational life of sensor is up-to 10 years and is highly accurate.
Highly Responsive
15 seconds is average responsive time for sensor making the senor swift and robust. Hence, this is a good choice for real time monitoring.
Energy Efficient
Sensor demands low power input (0 mW at 0 mV bias) for its function. This decreases the overall energy consumption.
Individual Calibrated
Individual calibration service procures readings with the highest accuracy for every device the sensor is put in.
RoHS Compliant
The sensor is in compliance with the Restriction of Hazardous Substances Directive (RoHS) for electrical and electronic equipment.
What technology is being used in CO Sensor?
The CO gas sensor uses electrochemical gas sensing. Its main components are a working electrode, a counter electrode, and an ion conductor. CO combines with electrolytes and oxidizes to generate water molecules and ions as it reaches the sensor. Sensors produce current as a result of this.
The electric current created by the directed passage of electrons across the wire is precisely proportional to the gas concentration. The gas sensor detects the passage of current between the two electrodes.
CO Sensor Calibration
Calibration is the process of comparing the actual/standard measurement to the measurement taken with your equipment or device. Calibrating the equipment or instrument improves its accuracy and measurement traceability. The sensor is subjected to CO in the range of interest to precisely calibrate it, and its response is compared to that of a reference Infrared Radiation (IR) CO analyzer. The target gas is compared to the NIST gas cylinder standard. Sensor calibration is carried out under normal ambient settings of 23 + 30°C, 50 + 15% relative humidity, 0.9-1.1 atm pressure, and 0.05m/s air velocity. The sensor’s sensitivity may be affected by changes in the environment, however, this is readily corrected.
