The tray is easily removable and rides silently on four plastic balls.
The interior of the bath is constructed of stainless steel and is designed for
operation with distilled water or equivalent. Do not use deionized water. The
acceptable resistivity range is 50K to 1M ohm (conductivity 1 to 20 micro
Siemans). The acceptable pH range is 7 to 9.
The body is made from galvanized steel and is painted for added protection. A
drain is located at the far left end of the bath. A stainless steel gable cover is also
provided with the bath.
The 230 volt units are identical in appearance to the 120 volt units.
