Four-ring Probe - The four-ring probe that comes with the HI8733 offers a versatile and accurate solution for conductivity readings. Four ring technology allows for a larger range of measurement within a single probe, whereas two probe technology is somewhat limited in the range in which it can measure. The probe comes with a protective PVC sleeve that assures durability when taking measurements outdoors.

 

Four Measurement Ranges - HI8733 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.

 

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 HI8733 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).

 

Adjustable Temperature Coefficient - As the temperature of a solution increases or decreases, the conductance becomes higher or lower, respectively. The temperature compensation coefficient, also known as β, is the factor that adjusts for the temperature of a solution to ensure an accurate reading is achieved. The HI8733 allows for an adjustable β to be set from 0 to 2.5%/°C; this factor corrects the conductivity reading by the set percentage for each degree Celsius change in the sample.

 

One-point Calibration -  The HI8733 can be calibrated at one point in a standard conductivity solution. The calibration knob located on the top of the meter is easily adjusted to the correct calibration standard.
