What does a MiniRAE 3000 detect?
The MiniRAE 3000 PID is the most advanced handheld volatile organic compound (VOC) detector on the market. It’s Photoionization Detector (PID) extended range of 0 to 15,000 ppm makes it an ideal instrument for applications from industrial hygiene, to leak and hazmat detection.
How do you use PID correction factor?
In our PIDs, correction factors can be used in one of three ways: 1) Calibrate the monitor with isobutylene in the usual fashion to read in isobutylene equivalents. Manually multiply the reading by the correction factor (CF) to obtain the concentration of the gas being measured.
How do I turn off the alarm on my MiniRAE 3000?
MiniRAE 3000: What is the procedure to turn off the alarm? MiniRAE 3000: What is the procedure to turn off the alarm? The answer / solution to the problem / question documented in this article. With the instrument turned on and running, press and hold the N/- and ON button for 3 seconds.
What do PID readings mean?
A photo-ionization detector (PID) uses low-wavelength UV light to eject electrons off target compounds in the air or other gas. The electrons and positive ions are measured as a current proportional to the concentration of the compound, allowing an accurate reading at levels as low as parts-per-billion (ppb).
What chemicals can a PID detect?
PIDs detect only those substances that can be ionized by the UV photons. This includes chlorinated hydrocarbons, formaldehyde, amines, methanol, aromatic compounds, some toxic VOCs, and some inorganic compounds, such as ammonia and hydrogen sulfide, all substances for which FIDs are not effective.
What gases does a PID detect?
A PID uses an ultraviolet (UV) light source to break down VOCs in the air into positive and negative ions. The PID then detects or measures the charge of the ionized gas, with the charge being a function of the concentration of VOCs in the air.
Can a PID detect chlorine?
The PID is also very sensitive to aromatic and chlorinated compounds, and can even measure some inorganic compounds that the FID does not detect at all (ammonia, carbon disulfide, carbon tetrachloride, chloroform, ethylamine, and hydrogen sulfide, to name a few).
What is a high PID reading?
A high FID reading with virtually no PID response might indicate the presence of methane. Consequently, PIDs respond very well to some inorganic gases that FIDs cannot detect. A high PID reading with no FID reading might suggest the presence of an inorganic compound.
What are PID readings?
Can a PID detect h2s?
What is Lel on a gas detector?
The term L.E.L. stands for Lower explosive limit of a combustible gas or vapor. It’s the lowest level a gas can ignite in air in the presence of an ignition source. Conversely, U.E.L (upper explosive limit) is the maximum level in air that a gas may ignite.
What gases can a PID detect?
How does the MultiRAE work?
RAE Systems’ MultiRAE multigas monitors give you the ability to detect and monitor up to six gases for personal protection and industrial leak detection applications. MultiRAE can test for VOCs in a range of 0-5000 ppm, combustibles, and a range of toxic threats, plus monitor sufficient oxygen levels.
