HMC1 Bacharach

Halocarbon Detector

QuestionAnswer
Is This Detector Intrinsically Safe? No, Some gases which this instrument can detect may be combustible/flammable. This instrument is designed to alarm at concentrations that are lower than the explosive limit of the gas
How long does Battery operation last 8-12 hrs
How long is the meters warm up time 5 minutes, Green light flashes during warm up, goes steady once finished
What is the measuring range for all gases? 0 - 10,000 ppm
What is the technology that is uses? Non-Dispersive Infrared.
What is the response time of the meter to get readings? -90% of response within 5 secs -100% in 7 seconds
how accurate are the readings? + or - 1ppm, + or - 10% of reading from 0 - 10,000ppm
What is the Low Alarm set to? 50 ppm , audible alarm
What is the High Alarm set to? 1,000 ppm, audible and visual red light alarm
Can the Alarm be silenced? Yes, Press silence button, alarm is silenced for 5 min, if levels remain above set limits alarm will sound again
How do you check the Battery Life? The battery is always on, the green button on the battery must be pressed for 5 secs, then view the reading on the LCD screen
Which setting do you uses for unknown releases? R22 - This is the one of least sensitive Halogen in library, so it will over report other halogen combinations
What does a Yellow light indicate? There is Fault with the meter. (Find fault codes by clicking FUNCTION / FAULTS) and view code, there is an external list of correctable codes that can be fixed in the field, the last 30 faults can be read on the meter.
Whats the max length for the gas sampling line? 50 feet
Whats the increase in the meter's response time for an extended sampling line? 1 sec for every foot of hose
What position should the meter be operated in? Use meter in its horizontal position (handle facing upwards). Tilting the meter to a vertical position while in operation may cause inaccurate readings
What does this meter detect? Detects gases with Halogen Carbon Bonds not just halogens alone
What is significant to Gases assigned a R number? When used in a closed system a rupture may cause O2 displacement
How many refrigerants are listed in the meters library 40 most commonly used refrigerants
How does Non-Dispersive Infrared technology work IR light goes into the sample chamber. There is an optical filter before the detector that eliminates light to look at a pre-measured wavelength of that gas. the absorbed light is compared to the selected gas and the concentration is derived from the diff
How can you determine what type of gas is leaking obtain a SDS sheet from the facility or any info from the cylinder that's leaking and look for synonyms for the gas involved that may be in the library
What are some common refrigerants this meter won't detect and why? -Chlorine, Bromine, Fluorine, Ammonia, Sulfur Dioxide, LPG - They do not have Halogen-Carbon bonds
How does the Zero Air filter work? -scrubs air through a carbon filter to ensure accurate readings -self zeros every 4 min -auto purges every 6-8 min -replace filter after 4hrs of 10,000 ppm exposure and yearly
