Liquid column manometers were among the first products manufactured by Sauermann (formerly KIMO) in France. Since those early days, the technology has evolved to include manometers with needle, pressure transmitters and, more recently, digital manometers, also known as pressure sensors. Our conventional manometers are designed for mains gas installations and for monitoring the condition of filters in ventilation systems. They are also used in clean rooms and laboratories requiring isolated atmospheres (differential pressure).
