HI9033

Description

The HI9033 is a rugged, portable EC meter designed for use in a wide variety of environmental conditions. It is supplied with a four-ring conductivity probe that can measure across four ranges. Conductivity readings are adjusted with Automatic Temperature Compensation (ATC), assuring users of consistent and accurate conductivity measurements.

• Automatic Temperature Compensation
• Four-ring probe
• Four measuring ranges

The portable HI9033 EC meter is suitable for use in a variety of applications. It offers four measurement ranges from 0.0 µS/cm to 199.9 mS/cm with a ±1% FS accuracy. The HI76302W four-ring conductivity probe that is supplied with the meter allows for a wide range of measurements with a single sensor. The four ring technology also eliminates the polarization effect that is common with standard two pole versions. The probe also features a built-in temperature sensor to allow for Automatic Temperature Compensation from 0 to 50°C (32 to 122°F).

Features at-a-glance
Automatic Temperature Compensation
•  Since temperature has such a dramatic effect on conductivity readings, having a meter that offers temperature compensated readings is invaluable.
•  The probe of the HI9033 features a built-in temperature sensor that automatically accounts for the effects of temperature on a sample’s conductivity reading in the range of 0 to 50°C (32 to 122°F).
•  The temperature compensation coefficient, also known as β, is set at 2%/°C; this factor corrects the conductivity reading 2% for each degree Celsius change in the sample.

Battery Error Prevention System (BEPS)
• The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements.

  Four-ring Probe
•  The four-ring probe that comes with the HI9033 offers a versatile and accurate solution for conductivity readings.
•  Four ring technology allows for a larger range of measurement within a single probe, whereas other meters with two probe technology is somewhat limited in the range in which they can measure.

  Four Measurement Ranges
•  HI9033 offers four conductivity measurement ranges. Each range has a dedicated button on the face of the meter, allowing users to easily switch between ranges when necessary.
•  The meter is programmed to let the user know when their current reading is out of range, and a new range should then be selected.

  One-point Calibration
•  The HI9033 can be calibrated at one point in a standard conductivity solution.
•  The calibration trimmer located on the top of the meter is easily adjusted to the correct calibration standard.
