Ask Bob
- To which standard(s) are GfG portable gas-detection instruments certified?
- After leaving an area where a reading has occurred, what procedures should be followed?
- Can the LEL sensors in the GfG instruments detect gasoline and kerosene? And can they measure the vapors of these petroleum derivatives?
- Parts-per-million or percent by volume measurements versus percent LEL measurements
- Which detection instrument do you recommend to determine the concentration of bacteria present in the air?
- We have both CO2 and HF produced in our process and also need to detect SO2, how do we rule out any interfering gases?
- If using a detector with an EC sensor for CO, will calibrating it using Nitrogen instead of air as Zero Gas affect the sensitivity of CO for this electrochemical sensor?
- Can hydrogen have an effect on CO readings, and can downloading the data help determine what’s going on?
- Is an LEL sensor dependable in an H2S LEL environment?
- What hazardous gases are associated with lead acid battery charging stations?
- Why is the ammonia in the calibration cylinder odorless?
- Detecting semi-conductor gases like SiCl4 & GeCl4 & GeCl2?
- Why do readings for H2S & NO2 go up when I breathe on the G460 sensors?
- Why is hydrogen such a big issue for CO sensors?
- What is the best concentration of calibration gas to use for instruments and for bump tests?
- What could cause a negative reading on a CO sensor?
- Can Alcohol vapors affect electrochemical CO sensors?
- What are manufacturer requirements for performing a daily bump test?
- Fluctuating or negative readings from a chlorine dioxide (ClO2) sensor?
- What are TLVs® & Why do They Matter?
