Infared gas sensors: Chillcard NG Range CHILLCARD NG For Refrigerants- R125, R134a & more... • Modern electronics platform with the increased power and versatility of fast microprocessors • On-board Barometric Pressure Correction in the range 800mbar - 1150mbar • Extensive Temperature compensation • Silicon micro-machined IR source • Long Term Stability • Low operating voltage (7V) and wide operating voltage range (7V - 30V) • True RS232 communications for control and data logging • Optional on-board LAN support • Expansion port supporting both simple 4 Digit and 128 x 64 pixel Graphic Display Modules The Chillcard NG range of gas sensor instruments, provide high accuracy detection and measurement of R-125 and R-134a refrigerants, where detection levels of 0 - 3000 ppm by volume are required. We also custom-manufacture Chillcard NG instruments to measure other refrigerant gases, please contact us directly to discuss your specific requirements. The Chillcard NG is suitable for a wide variety of applications and using the optional sampling pump it can detect gases from sampling points up to 30 metres away. The reliability, accuracy and long-term stability of the Chillcard NG, combined with its low maintenance requirements can be attributed to our proprietary dualwavelength infrared sensordesign and manufacturing experience. The Chillcard NG Instruments come complete with a range of useful optional extras and accessories.
