Sun Nuclear 1030 Radon Sentinel monitor with case. See attached photos. Selling for $800 plus shipping…I can process credit cards or pay by Paypal…Next calibration date is April 13, 2017. After my last calibration in April of 2016 the number 4 appears in the “alert” column on the report a few times. I asked Sun Nuclear about this and they said it was only used for programming and does not affect the function of the monitor. They said that when they do the next calibration in April 2017 it will go away. Send questions, etc…to gregwfox (at) yahoo.com…Monitor was kept in case 100% of the time when not in use.
