PCB screening kit
Clor-N-Oil kits, from Dexsil Chemical Corporation, are designed to detect the possible presence of polychlorinated biphenyls (PCBs) in transformer oil and to determine whether or not more extensive gas chromatograph tests are required.
The kit consists of two polyethylene tubes and a polyethylene bellows type disposable pipette. The screening process is a six-step series, which indicates when the total chlorine level is low enough that the PCB level cannot exceed 50 ppm and when it is high enough that the PCB level might exceed 50 ppm.

Underwater communications
Ocean Technology Systems now offers two different types of underwater communications systems for fire and police search/rescue dive teams.

The MK2-D/S unit is a through-water communication system providing the tender with lightweight portability and complete freedom of movement for the divers. The surface/tender portion was designed for use in small, inflatable boats or as a highly portable land base.
