I have 3 calibrated Sun Nuclear 1028 continuous radon monitors for sale.
This is one of the 3. See photos and make me an offer. You will be responsible for shipping and insurance cost. Actual cost. I will not overcharge the buyer for shipping.
If you would like just this one then make an offer on it. If you would like all three than make me an offer on them. Please no low ball offers. These things pay for themselves in no time.
