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.
