Granted a swing arm hydrometer can be off by a lot and it is important to know this.

However, if you measure the water that the animals come in and the water that you will be putting them in with the same peice of equipment, you will still be able to compare the difference in environments the animals will be kept in and be able to judge how much to acclimatize them from there.
