Product Description
Product Overview
The VQ10 Combustible Gas Detector Elements are designed for the detection of combustible gases, particularly methane in air mixtures, with concentrations starting from 0.1%. These matched elements offer low power consumption, making them ideal for battery-operated systems. They are unaffected by water vapor or carbon dioxide and provide a minimum sensitivity of 15 mV/% methane when used with the recommended bridge circuit. The detector elements are suitable for operation under direct flow or diffusion conditions and are built to withstand significant shock and vibration.
Product Attributes
- Brand: SGX Sensortech (IS) Ltd
- Product Type: Combustible Gas Detector Elements
- Model: VQ10
- Element Identification: Serial number on can (red for detector, black for compensator); red circular label on detector base.
- Protective Measures: Requires protection from certain organic and silicone vapors via suitable filtering; caution advised near hot, oily machinery.
