Hanna - HI98131 GroLine Hydroponic Waterproof Pocket pH/EC/TDS/Temperature Tester

The HI98131 is a slim, lightweight, and waterproof pocket tester that measures pH, conductivity (EC), TDS (ppm), and temperature. Simple, two-button meter operation and advanced features, including a selectable EC to TDS conversion factor (0.5 - 500 ppm and 0.7 - 700 ppm). for your essential testing.

- All measurements in a single, hassle-free tester.
- Quick Cal solutions to calibrate pH and conductivity all at once with a single solution.
- Perfect for hydroponics, greenhouse, and agriculture use. Features-at-a-glance 3 sensors in a single meter

- pH electrode with extractable junction
- Amperometric EC/TDS sensor
- Exposed temperature probe for faster EC/TDS readings Waterproof

- Designed to withstand the humidity of a growing environment Wide pH Range

- pH range is from 0.00 to 14.00 pH Selectable EC to TDS conversion factor

- Choice of either a 0.5 or 0.7 conversion factor
0.5 (500 CF) conversion factor is for an EC reading of 1000 µS/cm = 500 ppm
0.7 (700 CF) conversion factor is for an EC reading of 1000 µS/cm = 700 ppm Automatic Temperature Compensation

- All readings are compensated for variations in temperature
Temperature displayed in °C or °F along with pH, EC or TDS reading 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

- Selectable time before meter will automatically shut off to conserve battery life. Options are after 8 minutes, 60 minutes, or disabled.
