The Series Mark II Molded Plastic Manometers offer an ideal combination of precision, durability, and ease of use. Designed for a wide range of applications, these manometers provide accurate readings of low-range pressure, vacuum, and differential pressure in HVAC, laboratory, and industrial settings. The Series Mark II Molded Manometers are available in inclined and inclined-vertical configurations. The Model 25 features a curved inclined-vertical tube, offering higher measurement ranges with finer resolution at lower readings, making it ideal for general-purpose applications. Meanwhile, the Model 40 inclined gauge provides linear calibration and exceptional resolution across its entire range.
The Model 40 is ideal for air velocity and air filter gauge applications. Both gauge types can measure pressures above and below atmospheric levels, as well as differential pressure. Each Mark II manometer includes two tubing connectors for 1/8″ pipe or sheet metal ducts, two mounting screws, a 1-ounce bottle of indicating fluid, red and green pointer flags, and complete instructions. One of the standout features of the Series Mark II is its high-visibility scale, which enhances readability and accuracy. The precision-molded design eliminates errors associated with traditional glass tubes, ensuring reliable results in demanding environments. The Model 25 also comes with 8 feet of flexible double-column plastic tubing. For portable use, the optional A-612 stand allows easy transport. Additionally, a short piece of tubing can be placed over the Model 25 pressure connections to secure the gauge fluid during transit.
