Low Range pH/Conductivity/TDS Tester - HI98129
Features
Stability indicator
Meter displays a clock tag that will disappear when the reading has achieved stability
Hold button
Freezes reading on the display to allow recording of measurement
Beps (Battery Error Prevention System)
Meter will automatically shut off if there is not enough power to get an accurate measurement
Battery % level at startup
Low Battery Indicator
When the level is below 5%, the battery symbol on the LCD blinks to indicate a low battery condition.
Auto-off
Auto-off feature automatically shuts off meter after 8 minutes of non-use to maximize battery life
3 sensors in a single tester
pH electrode with extractable junction
Amperometric EC/TDS sensor
Exposed temperature probe for faster EC and TDS (ppm) readings
Waterproof
Designed to float if accidentally dropped in sample
Wide pH Range
pH range is from 0.00 to 14.00 pH
Selectable EC to TDS (ppm) conversion factor
Choice of either a 0.45 or 1.0 conversion factor
Automatic Temperature Compensation
All readings are compensated for variations in temperature
Temperature displayed in oC or oF along with pH, EC or TDS reading
Temperature displayed in oC or oF along with pH, EC or TDS reading
