Figure 1: Custom Display

The TPI 777 is a rugged personal gas monitor. Preset alarms
provide visual, audible and vibration alerts for low and high alarm
conditions. Built-in "Time Weighted Average" (TWA) and "Short
Term Exposure Limit" (STEL) alarms provide a greater margin of
safety for the user. A custom display provides easy to read
information including gas concentration and low battery indication.
