Just how often you are required to calibrate depends on you and the recommendations of the manufacturer. (See calibration intervals for more information.) There are several possible methods for tuning up your gas monitor, and whether you do manual calibrations, use an automated calib … read more

Don't Use Expired Calibration Gas to Test Monitors

Gas produced and put into bottles for bump testing and calibrating gas monitors has a finite shelf life, and paying attention to that expiration date might save your life. Using expired gas can lead to incorrect calibration of your gas monitor. Gas concentrations have been known to drop over time. Reactive gases such as hydrogen sulfide react with the material of the cylinder container … read more

How Many Bump Tests Do I Get From a Cylinder of Gas?

A good customer (all our customers are good, of course) recently asked us to figure out exactly how many bump tests they would get from a 58L of NIST Traceable Gas for their new Gas Clip Technologies Multi Gas Clip (MGC) Monitors (with 2 month battery charge life). The quick answer - a little over 300, and maybe as many as 600. But there's a catch. Calibration gas has a she … read more

You've got a couple of choices to get it working properly. And as everyone who owns a gas monitor knows - whether it's a multi-gas monitor like the GasAlert Micro Clip XT, or a single-gas monitor like the Gas Clip Technologies H2S Monitor -&n … read more

Which Regulator Do I Need For My Gas Monitor?

All gas monitors need to be bump tested, even if they don't require calibration. (Yes, that goes for you guys with single gas disposable monitors too.) To test your monitor you're going to need both calibration gas and a regulator. Your calibration gas mixture will be determined by the type of sensors in your gas monitor. Your regulator will have to fit your bottle of gas. Problem is there a … read more

How Often Should My H2S Monitor Be Bump Tested?

A customer from the Chinese division of a large petroleum company emailed us this week to ask how often their BW Clip H2S Monitors should be bump tested. Since we sell more of these monitors than any other at PK Safety Supply, it would seem logical that we'd have a ready answer. But we don't. It's not because we don't care, or we don't think it's important. It is. Here's the sit … read more

How to Calibrate your BW Honeywell Gas Monitor

Calibration is very important for a gas monitor. It reestablishes a base line accuracy for the sensors, both electro-chemical and LEL catalytic bead. In order to perform as they were designed, gas monitors need to periodically be readjusted in the same way a guitar string needs tuning. Calibration of your gas monitors isn't difficult or time consuming (unless you have several hundred monitors, … read more

How Often Do I Need To Calibrate My Gas Detector?

The Occupational Safety and Health Administration (OSHA) would like your gas detectors calibrated before each use. A full calibration for a 4-gas monitor requires about $6.60 worth of calibration gas, and takes about 5 minutes. This should be all the answer anyone needs, but in practice if your company has 500 monitors, it isn’t always practical and OSHA and ANSI know it. In text a … read more
