Approved by NI Dept of Environmental Protection for SAE J1667 snap acceleration, stall and rolling acceleration tests

In 1996 testing under auspices of the SAE J1667 Committee, the CalTest Model 1000 proved to be the most accurate in both the Brand A versus Brand B testing and in Manufacturing Consistency testing. It's the most simple to use. It's easy to clean, calibrate and is easily portable.The CalTest 1000 prints out four different types of snap reports (to the right is the SAE J1667 test procedure).

The SAE J1667 Committee decided correlation testing was necessary. They realized that sampling meter manufacturers often claim 4.2.1SAE J1667"calibration checks "passed" by their meters prove the meters are accurate...that exhaust opacity is estimated accurately. That claim is false. The test merely indicates whether sampling changer smoke opacity is being measured accurately. ISO/DIS 11614, an international authority, prescribes 9 extensive factory tests (which the user cannot do after purchase) to identify noncompliance with manufacturer’s specifications designed to ensure a "Representative Sample" is delivered to the smoke measurement chambers inside the sampling smoke meter.
Results of the testing of five makes of foreign and U.S. made full flow and partial flow (sampling) smoke meters The CalTest 1000 rated Excellent, with a close correlation with two other brands of full flow meters. The three sampling smoke meters tested showed poor accuracy.
