The Gas Tracer’s sturdy, high-impact plastic case is radio frequency
(RF) resistant and is suitable for use in many environmental
conditions, indoors and out. The case is dust proof and weather
resistant. A rubber layer on the outside of the case protects it from
scratches and impact damage.
A clear plastic window through which the LCD can be viewed is
located on the front of the case. Four brass charging contacts that are
used when the Gas Tracer is placed in the charging station are on the
back of the case. Both the rechargeable and alkaline version include a
removable battery pack. The battery pack release latch is on the
