    อุปกรณ์วัด Conductivity/TDS (EC and Resistivity Portable Meter)

    HI 87314

    EC and Resistivity Portable Meter


    • Supplied with two probes
    • Automatic probe recognition
    • On-screen operation guide
    • Automatic Temperature Compensation


    HI 87314 is a combination, portable meter that can read conductivity in four different ranges and resistivity.

    For conductivity measurements, a one-point calibration is performed via a trimmer located in the battery compartment. The supplied probe does not require recalibration when switching from one range to another. The four-ring (stainless steel) probe has a built-in temperature sensor that automatically compensates for temperature changes. The temperature coefficient can be adjusted from 0 to 2.5% using a knob on the front panel.

    For resistivity measurements, the meter is factory calibrated and, if necessary, calibration can be adjusted. The HI 3316D resistivity probe is easy to clean and requires little maintenance. It also features a built-in temperature sensor to automatically compensate for temperature variations. The temperature coefficient is user-selectable from 2 to 7%.

    Order Information:
    HI 87314 is supplied with HI 76302W conductivity probe, HI 3316D resistivity probe, HI 70030 calibration solution sachet, calibration screwdriver, battery, instructions and hard carrying case.
