COM-100 Combo EC/TDS/TEMP Meter Video Transcript
Hey everyone, Aquaman here with FilterDoctor.com. Today weíre looking as the HM Digital COM-100.
Now, HM Digital is an ISO 9001 certified company, which basically means they have to maintain extremely high standards for their manufacturing processes. That translate for you and me to extremely high quality products, and frankly, Iím convinced these are.
Now, the COM-100 is a combination meter. It can measure electrical conductivity, total dissolved solids and temperature.
Now, essentially the measuring process for electrical conductivity and TDS is the same, and itís just a different expression of the same factor. If you know the TDS, you can convert that into millisiemens or microsiemens and get electrical conductivity, or if you already know the electrical conductivity you can convert that to total dissolves solids. But, who wants to do that math? So the meter does it automatically for you.
Now, it has four scales; it can measure in millisiemens, microsiemens, in parts per million, and in parts per trillion. And it has automatic temperature compensation so that the conductivity or TDS readings are automatically compensated based on the actual temperature of the water. And the LCD screen will show the actual reading and the temperature right there so you can see it for yourself.
There are a number of other features, it is digitally calibrated so you donít need to mess around with the little tiny screwdriver, forget about that; nice push button calibration. It is 100% waterproof and in fact, will float if dropped in water and itís extremely accurate; down to .1 millisiemens or .1 parts per million. It has an auto shut off feature, a low battery life indicator because readings can become skewed as battery life deteriorates, and long life battery, approximately two year life on the battery.
The electrodes are platinum, so theyíre high quality electrodes, theyíre not going on the cheap here; this is a professional quality meter. Comes with a lanyard so you can throw it around your neck or your wrist so you donít drop it all the time.
This is the COM-100 from HM Digital, and Iím your host Aquaman with FilterDoctor.com.
Thanks for watching.
