RML-200 Microprocessor Four Range Lab Ratemeter

WB Johnson RML-200 Ratemeter

The RML-200 is an ideal ratemeter for labs and frisking stations. Furthermore, it is an inexpensive solution to area monitoring. The RML-200 ratemeter is a digital, all microprocessor controlled instrument with an analog display that automatically chooses the correct range (auto-ranging). Auto-ranging is ideal in stand-alone area-monitoring applications because no user intervention required. The RML-200 Ratemeter includes relay outputs for external sirens, lights, etc.
