Product Details:
Dwyer Instruments 477B-7 handheld digital manometer measures the pressure and flows in a patient's airway. Because the manometer is extremely precise, it is frequently used as a calibration standard, ideal for applications in HVAC system maintenance, fluid flow measurements and commercial furnace gas valve pressure measurement applications. This digital manometer is a portable, handheld meter that can monitor small changes in differential pressure.
Features:
- Dwyer 477B-7 handheld digital manometer measures dual and single pressures.
- This 9V alkaline battery-operated unit has an accuracy of +/-0.1% of full scale from 60 degrees to 78 degrees Fahrenheit for measuring negative, positive or differential pressures.
- It allows up to 40 readings that may be stored in the memory function for subsequent retrieval.
- The unit has a backlight that offers extra brightness for difficult-to-see areas.
- It also includes a hold function and both visible & auditory overpressure alerts.
- This model features an aluminium housing to protect the instrument against damage.
- It is supplied with a 4-digit LCD display for easy readings.
Compatible Accessories:
- Dwyer Instruments A-402A Pouch: These carrying cases feature tough grey nylon construction to protect the manometers. They are double zippered for quick and easy access with a belt loop that snaps closed.
- Dwyer A-47X-BOOT Rubber Boots: They are protective magnetic rubber boots and are used with the manometers.
Standards and Approvals:
- CE
Frequently Asked Questions:
Q. What pressure does a manometer measure?
A. Manometers are precise devices used to measure pressure which is defined as the force produced by a gas or liquid per unit of surface area due to the effects of gravity on the weight of that gas or liquid.
Q. What liquid is used in a manometer?
A. The most common fluids are alcohol, water and mercury.
Q. Why is alcohol used in a manometer?
A. Because of its low density, alcohol allows for a longer column than other fluids in manometers. It also gives the inclined tube a proper meniscus.
