PS4-ASH3-1

PS4-ASH3-1 is a PS1 series Arsine electrochemical gas sensor using a revolutionary ‘Solid Polymer Electrolyte’ technology that is based on the principle of catalytic reaction. The target gas to be measured generates a very small current, proportional to the gas concentration. The technology offers a stable, high-quality and cost-effective manufacturing process. Key applications include semiconductor industry and electronics factory.

• Small size, wide temperature range, fast response time
• No electrolyte leakage, extreme linear response up to high concentration
• Excellent sensitivity at low temperatures, low cost at large volumes
• Individually calibrated (including test report)
• 80 ±20nA / ppm sensitivity, measurement range from 0 to 1ppm
• ±2nA zero current, 20ppm maximum overload, T50 < 10s, T90 < 30s response time
• Less than 1% repeatability, 0.01ppm lower detectable limit, 1ppm linear range, < 60s warm up time
• Less than 0.02ppm resolution (16Bit ADC), pressure range from 800 to 1200hPA
• Operating humidity range from 15 to 95% RH (non-condensing), 100 ohm recommended load resistor
• 12 months storage life and warranty, PPO housing material, temperature range from -40°C to +55°C

Notes

Prohibited for military use. Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty.
