HM Digital COM-100 Water Tester - Waterproof Combo Meter for EC, TDS and Temperature

 

Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

 

The COM-100 is a professional level EC/TDS meter at a more than affordable price.

 

FEATURES

  • Measures electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature.
  • UPGRADED: Four scales: µS, mS, ppm, ppt (mS and ppt are new)
  • Three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl).
  • Automatic Temperature Compensation (ATC) using three temperature coefficients
  • Waterproof housing (IP-67 rating)
  • Measurement Range: 0-9990 µS; 0-8560 ppm; 0-9.99 mS; 0-8.56 ppt
  • Digital Calibration (push button) to any point within the meter's range
  • Auto-off function, data-hold function and low-battery indicator
  • Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
  • Replaceable Sensor (model SP-C1)
  • Factory Calibrated: The COM-100 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.
  • Includes a cap, batteries and lanyard.

HOW WE CAME ACROSS IT

In 2007 while living and working at the Creative Health Raw Food Intitute in Michigan, USA, we found that the Institute was using bore water for their main supply.  They would separate this water out into that used for toilets and showers and leave it as it was while the water that was being used for drinking, enemas, growing wheatgrass etc was put through a reverse osmosis system to take out the TDS (total dissolvable solids).  While these dissolvable solids can be both beneficial and harmful, it was important to keep in mind that the Institute sat out in the countryside and was surrounded by agriculture with a high chance of agricultural chemical run off getting into the water table.

 

So we decided to purchase ourselves one of these meters to be able to measure water quality for ourselves.  As an average, town supply drinking water needs to be measuring less then 50ppm to be considered ideal for drinking.  The bore water at CHI was measuring between 420ppm and 440ppm before reverse osmosis and then 12ppm after....so a great job done by the reverse osmosis process.

 

We would measure the town supply water purity as we travelled around the States and did not find a lot that fell into that ideal category.  Coming back to New Zealand we were hoping for a better average but were sadly disappointed and probably the TDS rate was boosted by the addition of both Chlorine and fluoride to most town supplies.

 

We currently purchase Living Water and we measure it regularly to keep an eye on the water purity and TDS (total dissolved solids) and it generally comes in at around 3 - 5ppm.  We prefer to add our own minerals thereby guaranteeing the quality of the ones going in and having surety around what they are.
