The UEI EM201B digital dual port manometer has an improved accuracy and provides a simple, time-saving alternative to U-tube pressure
measurements. It can measure gas supply and draft pressures in residential or
light commercial properties. The dual input manometer has a differential
mode which provides a convenient method to measure pressure drops.
- Dual input differential
measurement to -60 to +60" WG (water gauge or inches of water, inches of H2O);
-100 to +100 mBar
- Ruggedized with sturdy metal fittings
boot with built-in magnet (excellent for sticking to a furnace, fender etc.)
- Measures in inches water column, mBar, PSI, and Pa (auto range to hPa)
- Auto power-off after 5
minutes of no activity
- MIN/MAX value capture will capture values for both the minimum and maximum
- Data hold
- Back-lit display

To turn the meter on press
and hold the power button for 2
1. Zero the meter
Prior to use, the meter must be zeroed. To do
this, ensure the meter is in a non-pressurized area, press and hold the
ZERO button for approximately four seconds. The display will show 888 to
indicate that the zero function has occurred.
2. Measure Pressure
the flexible tube between the meter and the pressure source.
single input measurement use the positive input.
The positive input is to the right when looking at the front of the
meter. Positive pressures will display as positive results, and negative
pressure will display a negative result. To perform pressure with respect to a
different area connect a tube to the positive port, place the
end of this tube to the area to be measured and the negative port open.
Results will show the pressure in the target area with respect to the area the
meter is located. Use both the positive and negative ports to perform
differential measurements. Place the positive port in the area expected to have
a higher pressure, and the negative port in the area of lower expected pressure.
To select the desired units press SCALE. Repeated presses of this
button will scroll through PSI (pounds per square inch), In-Wg (Inches water
gauge, or water scale), mBar (millibar), or Pa (Pascals). On the
Pascal scale the meter will automatically switch to hectopascals (hPa) when the
reading exceeds 1000 pascals. 1000 pascals is equal to 10 hectopascals.
The EM201B will capture values for both the minimum and
maximum pressure measured. To reset press MIN/MAX until the display shows "- CLr". This will reset the values stored for minimum and maximum measured without
the need to disconnect and zero the pressure measurement. Captured values can be
displayed in any available scale.
The EM201B has a display hold
feature. Press this during reading to freeze the display. Press again to return
to actual measurement.
The EM201B has a backlit display.
Press to turn on or off the back light feature. The back light will stay on
until the button is pressed again
NOTE: using the back light will significantly
reduce the battery life.
7. OVER RANGE (OL)
If the input exceeds the meter
range OL will be displayed. Immediately disconnect from the pressure supply
safely to reduce chances of damage to the instrument.
