Mettler Toledo AT20 Microbalance Mass Comparator Lab Scale

Sale price$2,975.27


Unit was pulled from a working lab environment. It was said to be in working condition when it was pulled. We powered it on and seems to be working. Unit MAY NEED TO BE CALIBRATED BY BUYER. When we first powered it on, it would go through the setup then blink 0.0000. We did some research and reseated the weigh cell. It worked after powering it back on. It is missing the glass on one side of the internal glass cover (over the weigh cell). The top glass of that piece is also chipped. See photos for condition details.
