7777, I use a Bridge 2005 five gas analysier which was purchased in 2002 at a cost of 2700.00 USD. In addition to the hand held analysier I am using the PC software which I find highly useful in the diagnostic of engine emission control problems. Some of the features are: ability to calculate and display real timeLamba/air fuel ratio; it's small and light weight; it only takes me five minutes before it's at operating temperature; it performs data capture and with the optional printer (which is great to give an actual read out of each of the customer's trucks on a yearly basis along with the lead in for additional service work); it has an automatic calibration and zero function; the filters aren't that expensive and they are not difficult to change; it has a self contained battery charger which can be plugged into a cigarette lighter; it has a gas accuracy verification test protocol. See your LPG equipment supplier for any other information. I am sure they would be able to assist you.
For got one other place www dot bridgeanalyzers dot com
Yeah have not found anyone cheaper not sure that I would want to go cheaper.
thanks for the referal for the CO analyzer, is there one that will do the job for less $$$?
You can check with these guys www dot blankeindustries dot com
OSHA I believe specifies the in plant emissions standards that employees are exposed. The current in plant standards for CO is 15 ppm on a Time Weight Average basis. In plant emissions levels have more to do with the facilities air exchange system vs emissions from lift trucks, welding operations, etc. Obviously, ICE lifts are a contributor to in plant CO levels. But theoretically, you can have the cleanest burning lift truck engine made but operating where the air exchange system is poor you can exceed OSHA limits.
Lift truck tail pipe testers are used to verify the emission levels are in compliance with EPA Tier I, II, III etc levels.
I presume you/customer are wanting a "tail pipe" test kit?
Where I work we use a Blanke Industries CO meter.
I looked online before writing this and it appears that the exact model we use is not featured in their description.
But ours is the equivalent of the Model 1500 that is shown (in that it reads in the range from 0% to 10%).
The only difference is that the one we use is about 8 or 9 years old and DOES NOT feature a printer. It looks to be the same actual meter but without a printer.
Testing of CO emissions is a "2 pronged" situation (for want of a better description).
If OSHA or other authority performs a test or evaluation, it is most probable that the test sample will only be taken from the general atmosphere in the work areas, NOT from each vehicle exhaust pipe.
If the CO level exceeds the maximum permitted value, the employer must do whatever is needed to lower it to the permitted level.
BUT, the employer must be able to produce documentation proving that each IC engine in use in the work areas have been tested for CO emissions and are in compliance with the maximum standards allowed for tail pipe emissions coming from that specific vehicle (or engine).
So, it seems to me that a CO meter is essential for anybody working on IC industrial engines cause if you keep the tail pipe emissions of the vehicle in compliance.......the general atmosphere levels will be right too.
I have only been through 2 on site emissions tests where OSHA came in and tested and in each case ONLY the general atmosphere levels were sampled. No sampling was done on individual lift trucks.
