Product Description
HI9814 GroLine Waterproof Combo meter uses 1 combo probe to measure pH/EC/PPM/Temp. This combo meter is easily calibrated by using just 1 combo pH/EC/PPM calibration solution.
- Combo pH, EC, and TDS (ppm) probe design. Less cords and less caps = easier portable testing.
- QuickCal combo solution calibrates the combo probe on this combo meter... GroLine puts the combo in combo meter.
- Waterproof meter to test water in wet grow room environments... seems like a pretty obvious innovation doesn't it?
-
3 sensors in a single probe
- pH electrode - Preamplified for resistance to electrical noise including that generated by pumps and ballast
- EC/TDS sensor - amperometric two pole design
- Temperature - NTC sensor for accurate temperature measurement and compensation
-
Waterproof
- Designed to withstand harsh grow room environments
- Wide pH Range
- pH range is from 0.00 to 14.00 pH
- Selectable EC to TDS conversion factor
-
