Dwyer Instruments NCO 43000-0 Photohelic Gauge: Precision Pressure Measurement
The Dwyer Instruments NCO 43000-0 Photohelic Gauge is a highly accurate instrument designed for precise pressure measurement in industrial applications. It features a measuring range of 0 to 0.5 inches of water column (H2O) and provides reliable and stable readings. The Photohelic Gauge utilizes a diaphragm sensor that converts pressure changes into electrical signals, ensuring a quick response time and excellent repeatability.
Its rugged construction makes it suitable for harsh industrial environments, with a polycarbonate case that protects it from external elements. The NCO 43000-0 Photohelic Gauge offers various mounting options for easy installation and can be used for a wide range of pressure measurements, including air filters, ductwork, and gas lines. It is ideal for HVAC, environmental monitoring, and other industries where precise pressure control is essential.
Our HVAC supply store is your trusted source for this high-quality Dwyer Instruments NCO 43000-0 Photohelic Gauge. We offer competitive prices and fast shipping to meet your industrial supply needs.

Series 43000 Capsu-Photohelic® Pressure Switch/Gage
Lo-Limit and Hi-Limit Control, Aluminum or Brass Case Available
Series 43000 Capsu-Photohelic® Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Capsu-Photohelic® switch/gage employs an encapsulated sensing element for use with both liquids and gases at pressures to 500 psig (34 bar). Optional cast brass case is available for water or water based liquids. Two phototransistors actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width — less than 1% of full scale. Set points can be interlocked to provide variable deadband — ideal for control of pumps.
NIST CALIBRATION available in Product Configurator.
