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