About 500 data points can be logged for later transfer to a computer. It operates up to 6 hours on a fully-charged battery, and batteries can be changed in the field without loss of data. The RCL Monitor measures chlorinated hydrocarbons in 90 seconds, followed by a recovery period of 1 to 10 minutes. There is no humidity coefficient. The RCL Monitor was designed to be easy to use.
Control is via a touch panel and a four-line, backlighted display.
An identification number is assigned to each measurement to aid in logging, although date and time are also logged. A simple procedure transfers the logged data to an external computer. If high levels of combustible gases are possible, samples should be taken in one liter sample bags before measurement. The RCL Sensor should not be exposed to excessive concentrations of chlorinated hydrocarbons. Sensor is consumed with time.
