The 29-year-old joined this week after a spell in the third tier of German football, where he previously played for Bayern Munich reserves.
Adams also saw winger Ivan Sproule score twice on his debut in last weekend's 4-1 win at St Mirren Park, with Sam Morrow coming off the bench to hit his second goal of an injury-affected campaign.
Adams said: "Steffen has been here for a few weeks now and he's looking forward to getting started. He'll go into the squad and we'll see if he is part of the 18. He's a strong attacker, he's six feet plus, he takes the ball in well, has good technical ability, a good idea of the game.
"We have got good competition there with Gary Glen, Steven Ross and Sam Morrow. Sam's had a bit of a lift with Ivan Sproule, an old team-mate from Hibs, coming in. That's given him a bit of a bounce.
"He's a player that's got undoubted ability, now he's got to find that consistency. I'm really hopeful that he becomes a big part of our season."
County are looking for their third successive SPL win following an earlier triumph against Hibs at Easter Road.
Adams said: "Dundee United are a side we have done well against this season. I know we have drawn one and lost one but performances, we have been happy with.
"They are a team we have struggled to win against in the past but let's see if we can make it three wins from three away from home. We have played 21 games and got 24 points. We are close to the teams above us and we have played less games.
"Some of these teams have had so-called excellent starts to the season so we have started exceptionally well in our first SPL season. Let's see if we can finish the season on a high."
