AP-2 Conductivity and Temp Meter Video Transcript

Hey everyone, Tony the Filter Doctor here. Today we’re looking at the HM Digital AP-2. Now, the AP-2 is a combination conductivity and temperature meter. It comes from the factory pre-calibrated with a range of 0 to almost 10,000 microsiemens. It also measures in Fahrenheit scale from 32 to 176 degrees, and Celsius from 0 to 80 degrees. Now, it does have an accuracy of about 2% on either reading; either conductivity or temperature. It has an auto shut-off feature after five minutes of non-use, and uses a single 3 volt button battery with an extremely long, two year expected life. It’s also magnetic which is really convenient because you don’t have to worry about where you put it last time, just stick it to the nearest metal surface where you typically use it and it will always be there for your convenience. Now, conductivity meters are similar to total dissolved solids meters. The two measurements can be converted back and forth, so if you know the conductivity, you can mathematically calculate the total dissolved solids, and the reverse is also true. You may want a conductivity meter because you have a specific application where you need your numbers in microsiemens and you simply don’t want to do the math every single time you use your meter. So, choosing an electrical conductivity meter over a TDS meter is probably going to happen in a laboratory application or some other specific industrial or commercial application where you just simply need microsiemens and not parts per million. Again, this is the AP-2 from HM Digital, and I’m Tony the Filter Doctor. Thanks for watching.
