Hello all, I am selling a Sun Nuclear Professional Continuous Radon Monitor, Model 1027. I began may home inspection career in Colorado where a Radon monitor was needed for almost every home inspection; however, I moved to Texas where Radon levels are low and clients do not request a Radon test. So, I am selling my additional monitor. I purchased the unit new from Sun Nuclear in May, 2015 and it is in excellent shape. The monitor was last calibrated in December of 2018 and comes with hard case and power cord… Selling for $600.00 and I will pay for shipping. email me at email@example.com if you are interested.
