| | | The 'Chillcard II' range of gas sensor instruments provide high accuracy detection and measurement of R-125, R-134a, R-123, R-11, R-12 and R-22 refrigerant gas, where detection levels of 0-1000ppm by volume are required. (We also custom-manufacture Chillcard II instruments to measure certain other refrigerant gases - please contact us to discuss your specific requirements.) Suitable for a wide variety of applications these gas sensors can detect gases from sampling points up to 30 metres away, using the optional sampling pump. | | The reliability, accuracy and long-term stability of the Chillcard II, combined with its low maintenance requirements can be attributed to our proprietary dual-wavelength infrared sensor technology and over thirty years of sensor design and manufacturing experience. The Chillcard II instruments come complete with a range of useful optional extras and accessories, including 4-digit LCD's, DC pumps and RS232 interface adapters for advanced output signal processing. | | |
