Exhibiting high performance with longterm stability, this compact (20.4mm dia) sensor is suitable for portable Gas Detection Instruments or Fixed Gas Detection heads. Nemoto's porous electrode technology enables accurate gas detection with high sensitivity. The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage. Specifications NT-CO Detectable gas: Carbon Monoxide Detection range: 0 – 1000 ppm Maximum range (short periods) 2000 ppm Output current: 75 +/- 15 nA/ppm Reproducibility: +/- 2% Zero in clean air: <+/-5ppm equivalent Output drift in air: 2 years Operating conditions: Operating temperature: -20°C to + 50°C Humidity range (constant) 15-90% RH Humidity range (intermittent) 0-99%% RH Pressure: 0.9 – 1.1 atm Recommended resistor: 10 ohms Bias voltage: Not required Recommended Storage temp 0-20°C Storage time 6 months (without compromising lifetime) Typical Signal / Temperature Profile, NT-CO 0 20 40 60 80 100 120 -20 -10 0 10 20 30 40 50 temperature (deg C) % of signal @ 20 deg C Further performance data and information on operating characteristics will be available in the Characterisation Document NTCO-CD Nemoto has a policy of continuous development and improvement of its products.
