Description
“-TESTMETER” can be added on to all of the gas meters above except the HIQ-SK-25EX
Test Meters are particularly advantageous in applications where minute amounts of gas must be measured with a high degree of accuracy. They are used in factories, laboratories, testing departments, and precision air sampling trains.
One of the more popular uses of this type of meter has been in the area of pollution control & sampling. The Environmental Protection Agency has set standards of performance for limiting gaseous and particulate emissions from factories. Federal, state, and local pollution control authorities have discovered a need for dependable precision instruments to sample and evaluate pollutants. Test Meters are being implemented in stack sampling and pollution monitoring equipment.
Test Meters come equipped with a special test index. This index has a sweep hand, which could be compared to the sweep hand on a stopwatch. The sweep hand circle is finely graduated so that accurate measurement of minute amounts of flow can be accomplished. Timing of the sweep hand also allows for the accurate establishment of small flow rates.
The test index used on the S-275 through the #415 has a sweep hand, which makes one revolution for each 1/10 cubic foot of gas consumed. It may easily be read to the nearest 0.005 cubic foot and has a maximum reading of 999 cubic feet. Upon request, this group of test meters can also be equipped with an index whose test hand makes one revolution for one cubic foot of gas consumed.
