PROBE OPTIONS

There are several options available with the MAC155 Probe. Each option is

explained in detail in the following sections.

EXTENSION TUBE

The optional extension tube is 3 foot/0.9 meter in length and can be affixed to

the end of the MAC155 Probe using standard tube fittings. The purpose of the

extension tube is to draw the sample atmosphere at a point well away from the

wall of the stack or duct. The 3 foot/0.9 meter extension tube can be cut to any

desired length.

when the instrument is mounted outside in geographic locations where the

ambient temperature may fall below 32°F / 0°C. The case heater option will

protect the unit from freezing to temperatures as low as -40°F / -40°C. The case
