668-16

668-16 is a low cost series 668 bi-directional differential pressure transmitter capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization, HVAC and air flow control. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Compact, lightweight design makes installation simple and easy. Units also feature reverse-polarity protection.
