Tips: What does it mean, the gas units PPM, %LEL, %VOL in multi-gas detector's specification?

1. PPM
PPM refers to parts per million, a unit of gas volume concentration.
For solution: it means that there’s 1/1000 ml solute in the 1L aqueous solution, so its concentration is 1ppm.
For gas: it’s one of representation method of pollutant concentration in the ambient atmosphere (air).
2. %LEL
LEL refers to the lower explosive limit. When the combustible gas reaches 100%LEL, it’s easy to explode, and the explosion occurs as soon as contacting an electric spark. Therefore, 0-100%LEL generally refers to the range of combustible gas measurement. For example, hydrogen: 4%VOL=100%LEL, methane: 5%VOL=100%LEL.
3. %VOL
VOL refers to the volume ratio of target gas in per volume. It’s generally used for high concentration. 1%VOL is equal to 10000PPM, and generally it is for oxygen and combustible gases. For example, how much oxygen in a space.

Operation and Setup of Portable Gas Detectors

This video explains how to operate and set up this portable gas detector.

Portable Oxygen Gas Detector with PC Interface

The Smart Handheld Gas Detector from ATO is designed to detect oxygen in a range from 0% to 30%. In this video, ATO will show you that the detector uses a micro sampling pump to draw in the measured gas with the max flow rate up to 1L/min. The LED display provides simultaneous pickup of gas variety, density units, the maximum value, local time and atmospheric temperature, etc.

I do have some additional questions though

I do have some additional questions though. What is the accuracy of all channels? Can the device be delivered with an outlet port such that vent gas can be sent to a safe location? For example, can a ¼” BSP female connection be provided at the outlet port? Regarding the frequency, and correct me if I’m wrong, electrochemical analysis is batch wise, meaning that you can have a maximum amount of analysis cycles per time unit. What would that be for this device?

ATO Responded

1. All channels have an accuracy of 2-3%FS.
2. The instrument has an air outlet and can be connected to a safe location.
3. Sorry, we have Not calculated this analysis cycles.

We need to ask some questions about the gas detector.

Can you add wireless function to your handheld gas detector, so can you get the data directly to my PC?

ATO Responded

Yes, we can add a wireless module to the handheld gas detector, so you can monitor and record data on your PC.

Calibration Password

Hi, I needed a password to calibrate the gas meter.
thank you
