Detail:

The Land Model 4500 MkIII has reset the industry standard on compliance opacity and dust concentration measurement. Combining the unique features of three patented technologies,
the 4500 MkIII achieves the highest available specification for the principal performance parameters, as defined by the internationally recognized ASTM Standard B 62161. These
industry-leading features makes the MkIII the most accurate opacity monitor available today. Its excellent sensitivity makes it ideal for all current or future requirements in opacity and dust
concentration measurement.
