Drop Test is an app to calibrate/measure the chemical dosing pump output. It is intended to be used in a water/wastewater treatment process. This app was developed for personal use only but anyone working in a similar field are free to use this app.

How it works:
- There are pre-loaded chemicals and pump numbers that you can edit to suit your application. You need to find out the specific gravity and concentration of your chemicals to calculate the Yield. You'll find these info from the chemical delivery dockets.
- The chemical yield is SG x Conc eg: specific gravity x concentration.
- You can change unit of measurement for flow and volume by tapping the buttons.
- When everything is filled-in, the calculated dosage will be displayed instantly as soon as you tap "Stop" button.

The dosage is calculated as follows:
Volume dropped(Liters) x Yield x 24 x 60
divided by:
Plant Flow (ML/d) x Time (secs)

which gives results in mg/L.

- The old pump list is now included in the chemical list. This way when you select the chemical yield it creates the pump list for that chemical only.
- This version will now remember the information you have entered.
- The timer will keep running even after closing the app. Good if you have to do something else like answering phone calls.
- The countdown is now gone and replaced by Presets. The default is 60 minutes. So if the timer was left running, it will stop at the preset time.

version33- problem with Share button fixed.

versdion32- multi drop test working

version31- Multi-dropTest disabled until the bugs are fixed.

GOOD NEWS!!! This app will now allow you to drop test 4 pumps at the same time. When drop testing more than one pump, make sure you have enough chemicals in your drop test cylinder. You don't want your pump to run dry!!!
