GROLINE Hydroponic Waterproof pH/EC/TDS/Temperature Meter Pen HI98131

Producer: HANNA Instruments

SKU: HANNA-HI98131 Category: Hanna experimental measuring equipment

GROLINE Waterproof pH/EC/TDS/Temperature Meter For Hydroponics

– Measure pH/Conductivity(EC)/Total Dissolved Solids (TDS)/Temperature.

– Compact, pocket-friendly design.

– The pH electrode is removable and replaceable.

– Automatic temperature compensation.

– TDS coefficient 0.5 (clean water) or 0.7 (hydroponics)

– HQuick pH and EC/TDS calibration with just 1 solution (Quick CAL)

– Meter included electrodes and standard solutions, electrode washing.

REMOVABLE pH ELECTRODES

The HI98131 waterproof, highly accurate EC/TDS meter with fabric junction.

Extended cloth junctions extend electrode life and replaceable pH electrode (HI73127)

Additionally, the replacement electrode has no pins so it won't bend or break.

EC/TDS GRAPHIC DETECTOR

The conductive graphite probe provides higher accuracy because it is not contaminated by salts in the solution.

AUTOMATIC TEMPERATURE COMPENSATION

The machine integrates a temperature sensor for quick response time and ensures temperature compensation for highly accurate measurement results.

AUTOMATIC QUICK CAL

– With only 1 HI50036 solution to calibrate pH.EC.TDS at the same time without having to calibrate each point separately.

– In addition, the machine can also calibrate each pH and EC/TDS index.

+ pH: Calibration at 2 points at pH 4.01 / 7.01 / 10.01

+ EC/TDS: 1 point calibration at 1.41 mS/cm or 5.00 mS/cm

hi98129-hi98130

HOLD BUTTON

Helps keep a stable value on the screen to facilitate recording and storing measurement values

STABLE SYMBOL

The hourglass icon will flash during measurement and disappear to indicate that the measurement result has stabilized and this value has been taken.

SUPPLIED COMPLETE SET WITHOUT PURCHASING ANYTHING ADDITIONAL

– Meter and internal pH, EC and temperature electrodes

– Quick calibration solution

– Electrode cleaning solution immediately after measurement
