Comments

System can monitor interstitial spaces.
AGW-Gold Sensor Cable is reusable.
TFH Hydrocarbon Sensor Cable is not reusable.
Cable is assumed to be equally or more sensitive at shorter lengths.
AGW-Gold Sensor Cable is distinguished from AGW Sensor Cable by a golden color braid wire and black polymer overbraid.
