Product Overview

Parts or repair, no power up

Hach Sigma 900 MAX Controller / Pump

We were unable to power up with our 12V supply, checked the fuse and it was blown. We did not have a spare to try to power with. We then opened  and found that the ribbon cables and cables were not attached to the board, just as you can see in the photos. Also the battery had leaked as shown so we removed the batteries.

Being sold a Parts or Repair unit, AS-IS, no returns due to no being able to power.

Free shipping to the 48 contiguous states in the USA.

Item was as described, and very fast delivery!

5 stars across the board for every seller rating category, and I would buy from this seller again. And per my request, the capacitors were also very well packed for safe delivery.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
