HM TDS Meter
The TDS pen is Ideal for all water purification applications, wastewater regulation, aquaculture, hydroponics, and colloidal silver. Perfect for both consumer or commercial use. Carry one in your pocket or toolbox at all times.
Automatic temperature compensation (ATC)
One-point calibration
It is widely used for monitoring EC/TDS in drinking water, water conditioning, reverse osmosis, cooling towers, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics and the printing industry.
- Ideal for commercial use. Includes a carrying case with belt clip.
- Highly efficient and accurate due to its advanced microprocessor technology.
- Hold Function: saves measurements for convenient reading and recording.
- Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
- Measurement Range: 0-9990 µS. From 0-999 µS, the resolution is in increments of 1 µS. From 1000 to 9990 µS, the resolution is in increments of 10 µS, indicated by a blinking 'x10' image.
- Built-in digital thermometer Display: large and easy-to-read LCD screen.
- Factory Calibrated: The EC-3 has been factory calibrated to a 1413 µS KCl solution. Meters can be recalibrated with a mini-screwdriver.
