The PV350 Pressure/Vacuum Transducer Module (the module) measures gauge pressure; the difference between atmospheric (barometric) pressure and the pressure (or vacuum) applied to the pressure port on the transducer. It then converts that measurement to 1 mV dc per unit. A module and a high-performance digital multimeter (DMM) with min/max function become a datalogger capable of measuring peak high and peak low.
A building should only let in outdoor air at design points where it is intended. The ventilation should be efficiently distributed to areas where it is required. Tools in this category will help diagnose problems with the building envelope and air distribution within the space. Measurements possible with these tools include tracking air pressure, air quality, leakage, and air flow.
Identify areas with low or substandard ventilation. Identify hidden energy savings in over-ventilated spaces. Determine if ventilation is a factor in air quality complaints. Locate the presence of combustion fumes from vehicles and appliances. Use as a reference to calibrate wall mounted CO2 sensors.

The S220 Smoke Pen contains a patented smoke-emitting wick that is lit with a cigarette lighter or match. The glowing tip emits smoke for as long as you need. A single wick will emit smoke for up to half hour, but can be start and stopped by capping and relighting as needed. There is no waste; no mess—only safe non-toxic smoke. The unused portion of the wick stores safely in the barrel of the pen.
Select the Dwyer Magnehelic gage for high accuracy - guaranteed within 2% of full scale - and for the wide choice of 81 ranges available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems.
The Fluke 117 Electricians Multimeter is a compact, CAT III 600 V, True-rms meter that includes an easy-to-use interface with a bright backlight for darker worksites. It saves you time and enables you to move from job to job more quickly. With a quick turn of the dial you can get measurements for:
