Product Description

Product Description

The ES4-PH3-2000 Phosphine Gas Sensor is a highly reliable and accurate sensor designed for the detection of phosphine gas (PH3) in a variety of environments. Utilizing advanced solid polymer electrochemical sensing technology, this sensor provides excellent performance for applications such as TLV (Threshold Limit Value) monitoring and food insecticidal environments.

Key Features:

• Amperometric Technology: The sensor operates based on a 3-electrode amperometric method, offering a fast and stable response to phosphine gas.
• High Sensitivity: With a sensitivity of 110 nA/ppm ± 30 nA/ppm, the sensor offers precise detection even at low concentrations of phosphine.
• Wide Detection Range: The sensor has a detection range from 0-2000 ppm and can withstand overloads up to 5000 ppm.
• Fast Response: The sensor features quick response times with T50 < 10s and T90 < 30s, ensuring rapid and accurate readings in real-time applications.
• Low Power Consumption: Operating with a bias voltage of 0 mV, the sensor is energy-efficient and suitable for long-term deployment.

Environmental Tolerance:

• Temperature Range: The sensor operates effectively between -40°C and +55°C, ensuring reliable performance in diverse environmental conditions.
• Humidity Range: With a humidity tolerance of 15-95% RH (non-condensing), it is suitable for use in varying moisture conditions.
• Pressure Range: It functions within a pressure range of 800 to 1200 hPa, making it adaptable to different atmospheric pressures.

Long-Term Reliability:

• Long Lifespan: The ES4-PH3-2000 sensor offers an expected lifetime of over 3 years in normal air conditions.
• Zero Drift: In clean air, the sensor exhibits minimal zero drift, less than 0.2 ppm, maintaining long-term accuracy and stability.
• Long-Term Drift: The sensor experiences a drift rate of less than 1% per month, ensuring consistent performance over time.

Cross-Sensitivity:

The sensor is designed to be minimally affected by cross-interfering gases, with no significant interference from common gases like CO2, CO, and CH4, among others. This feature ensures the sensor provides accurate phosphine readings even in environments with varying gas compositions.

Applications:

• TLV Monitoring: Ideal for environments where phosphine gas levels need to be continuously monitored to ensure safety.
• Food Insecticidal Environment: Effective for monitoring phosphine gas used in fumigation processes.
• Industrial & Research Applications: Suitable for a variety of industrial and research applications requiring precise phosphine detection.

The ES4-PH3-2000 Phosphine Gas Sensor is individually calibrated for accuracy and comes with a test report for guaranteed performance. It offers a cost-effective solution for large-scale deployment in safety-critical applications, ensuring precise and reliable detection of phosphine gas.
