Dwyer Instruments 1223-36-D Manometer
The Dwyer Instruments 1223-36-D Manometer is a heavy-duty U-tube manometer engineered for precision pressure measurement in demanding industrial environments. This dual-column gauge features a 36-inch scale length with an 18-0-18" w.c. range, providing high-resolution readings for positive, negative, and differential pressures. Constructed from shatterproof clear plastic tubing mounted to a rigid white vinyl scale, the 1223-36-D utilizes .826 sp. gr. red gauge oil to deliver a highly visible, sharp meniscus for accurate data logging. Designed with a flexible reservoir and overpressure safety traps, this dual scale manometer prevents fluid loss during pressure surges. It is an essential diagnostic tool for HVAC system balancing, monitoring industrial draft pressures, and verifying static pressure across ductwork or filtration banks, ensuring systems operate within designed flow parameters.
Technical Specifications and Benefits:- Precision Measurement: Optimized for low-pressure applications requiring an 18-0-18" w.c. range with high-contrast red oil.
- Industrial Durability: Rugged construction utilizes clear shatterproof tubing and a chemical-resistant white vinyl backing for longevity in the field.
- Safety Features: Integrated overpressure safety traps eliminate fluid blowout during sudden pressure spikes or improper disconnects.
- Flexible Calibration: Adjustable zero-point scale allows for rapid field calibration and accurate differential pressure readings without complex electronic sensors.
- Versatile Compatibility: Standard 1/8" NPT connections ensure seamless integration with existing HVACR testing kits and pressure probes.
How do you calibrate the Dwyer 1223-36-D in the field?
Zeroing the instrument is achieved by sliding the adjustable scale until the zero mark aligns perfectly with the fluid meniscus while both ports are vented to the atmosphere.
Why is red gauge oil used instead of water in this manometer?
The .826 sp. gr. red oil provides a more distinct meniscus for better legibility and prevents evaporation issues common with water-filled gauges, ensuring long-term accuracy in static pressure measurement.
What is the maximum pressure rating for this U-tube manometer?
While designed for atmospheric and low-pressure ductwork, the 1223 series is rated for internal pressures up to 100 psi, though readings are limited to the physical scale of 36 inches of water column.
