Edinburgh Instruments is extending its range of high-performance, low-cost, dual-wavelength OEM gas sensors. Designated the Gascard II Plus range, the new models feature high accuracy with low drift characteristics and are designed to be integrated into analysis systems and equipment used to measure total organic carbon (TOC), indicating the quality of sample water with respect to the concentration of organic pollution. This range provides high-accuracy measurement and detection of sub-1 per cent levels of CO2. They use established and proven pump-aspiration technology to provide rapid detection and response.
The rugged sensor design of the Gascard II Plus provides accurate and reliable measurement with a response sensitivity to measure 1ppm gas concentrations. Reliability is further enhanced by the absence of moving parts in the sensor.
Measuring only 100 x 160 x 40mm (eurocard format) and weighing only 0.3kg, these products are suitable for integration into a wide variety of enclosures. The operating temperature is 0-45 degrees C, with a power requirement of 24V DC (18-30V) and power consumption of 6W maximum.
These innovative gas sensors have user-selectable linear and analogue output options, alarm function software and automatic temperature correction. An optional four-digit liquid crystal display (LCD) is also available.
Each Gascard II Plus is supplied fully tested and calibrated with a two-year warranty against defective workmanship and parts.
Edinburgh Instruments can also design and manufacture variants of the Gascard II range to customers' requirements.
These versatile products have applications in the water, food, beverages, process, engineering, laboratory and manufacturing industries.
