It is a sensor you wire in and forget, giving a continuous voltage that rises and falls with the radon level.

On a 0 to 400 sensor the same voltages give a tenth of those numbers. A 0 V reading is not a low radon reading, it means the sensor needs service.\u003c\/p\u003e\n\n\u003cp\u003eThe output range is set at the factory. If you are specifying ROBIN into a control system, confirm the exact output range for your variant with us before you wire it, so the scaling in your controller matches the unit that arrives.\u003c\/p\u003e\n\n\u003cp\u003eROBIN applies its own smoothing before it outputs, so the signal does not jump around on a single hour of noisy data.

A radon test that has to be reported or relied on still needs a C-NRPP listed measurement device or a lab analysed detector. Use ROBIN to run a building, and a listed device to prove a number.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat will it connect to?\u003c\/strong\u003e Anything that accepts a standard analog voltage input: a building management system, a PLC, a fan speed controller, or a logging input on existing plant.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need any radon training to install it?\u003c\/strong\u003e No. It is a four wire sensor with a voltage output.
