New product focus: Ultra View Temperature (& Humidity) Chamber When the job requires continual work using the hands inside the reach-in ports, the releasing hinges allow for completely removing the covers. → → Photo 3 Removing the reach-in port covers on the viewing window Interior lighting (fluorescent) is built into the upper section of the door. The bulbs can be easily replaced with no halt in testing. A dew condensation tray is also built into the lower section of the door to prevent water dripping onto the floor when the door is opened.
