Does it measure manganese in water ?

This gives an overall measurement of all minerals. It provides a single number of parts per millions. It cannot provide a break out of the different minerals. Your local water utility/supplier can often give you the analysis of your local water. That is, they can tell you the amount of manganese in your local water. Hope this helps.

Does it measure the water hardness?

Yes. The purpose of a TDS (Total Dissolved Solids) is to measure water hardness. The basic answer is the higher the number the harder the water. The lower the number the softer the water. The general rule of thumb is // 0 - 99 is ideal // 100 - 199 is good // 200 - 299 is average // 300 - 399 is marginal // 400+ is hazardous //. Like I said this is just general rule of thumb. The pen is actually pretty accurate for the price and has been effective for my shrimp tank.

batteries constantly drains and die even with product off! any one else with this issue or any ideas to fix?

I have not had a problem with the battery draining...it has the same batter from when I bought it...
