Description
The PS500 is used for confined space applications, eg, in sewers, underground piping or within tanks, and other personal monitoring applications. Its high intensity audible and bright visual alarms provide early warning of dangerous gas levels and its single button operation makes it a very simple to use portable gas detector.

Each toxic sensor has 2 instantaneous alarm set points, plus user exposure alarms. The PS500 will calculate the Short Term Exposure Limit (STEL) and Long Term Exposure Limit (LTEL), known as Time Weighted Average (TWA) readings. The TWA value is the mean average gas level over a specific time period. The STEL is 15 minutes and the LTEL is 8 hours. This averaging makes the instrument single user applicable, but an option is available to reset the averaging after each power off, allowing multiple user use.
