    อุปกรณ์วัด Conductivity/TDS (Gro’Chek EC/TDS/Temperature Monitor high range EC and TDS measurement)

    HI 993302-01

    Gro’Chek EC/TDS/Temperature Monitor
    high range EC and TDS measurement

    • Waterproof
    • Measure in °C or °F
    • HOLD function
    • Adjustable TDS ratio
    • Adjustable β
    • Stability indicator
    • Backlit display
    • 12 VDC power supply


    Waterproof and chemically resistant, HI 993302-01 has been designed to meet the grower’s need for equipment suited to the aggressive environments found in agricultural and hydroponics applications. At startup, HI 993302-01 performs a self-check to ensure proper working condition.

    This monitor from HANNA has a backlit LCD and displays instantaneous readings of both EC or TDS and temperature—even from a distance.

    This instrument features a stability indicator that prompts the user when to take the reading. For manual recording purposes, readings can be frozen on the LCD display by pressing the HOLD button.

    Calibration and temperature compensation are automatic, while the EC/TDS conversion factor and temperature coefficient factor (β) are user adjustable for application specific measurements.
