The HI8733 portable multi-range EC meter provides a versatile solution for measuring electrical conductivity across a wide spectrum of applications. Offering four distinct measurement ranges, from a highly sensitive 0.0 µS/cm up to 199.9 mS/cm, this meter delivers reliable accuracy within ±1% of full scale. The included HI76302W four-ring conductivity probe is engineered for broad measurement capabilities using a single, robust sensor. This advanced four-ring technology effectively eliminates the polarization effects commonly observed with traditional two-pole probes. Furthermore, the probe integrates a built-in temperature sensor to enable Automatic Temperature Compensation (ATC) within a range of 0 to 50°C (32 to 122°F), along with a user-adjustable temperature coefficient (β) from 0 to 2.5%/°C.
Key Features at a Glance
Innovative Four-Ring Probe: The HI76302W probe utilizes four-ring technology, providing a significant advantage over conventional two-pole designs. This allows for accurate conductivity readings across a much wider measurement span with a single probe, enhancing versatility and eliminating the need for multiple sensors. The probe is also encased in a durable PVC sleeve, ensuring resilience for both laboratory and field use.
Versatile Four Measurement Ranges: The HI8733 offers four dedicated conductivity measurement ranges, each easily selectable via a front-panel button. This intuitive design allows users to quickly adapt to different sample concentrations. The meter features an out-of-range indicator, prompting the user to select a more appropriate measurement range for optimal accuracy.
Intelligent Automatic Temperature Compensation (ATC): Recognizing the significant impact of temperature on conductivity, the HI8733 incorporates automatic temperature compensation. The integrated temperature sensor within the probe automatically corrects conductivity readings for temperature fluctuations between 0 and 50°C (32 to 122°F), ensuring reliable and temperature-independent results.
User-Adjustable Temperature Coefficient (β): To further enhance accuracy for various solution types, the HI8733 allows for a user-adjustable temperature coefficient (β). This setting, ranging from 0 to 2.5%/°C, enables the meter to compensate for the specific temperature-dependent behavior of different solutions, ensuring highly accurate conductivity readings tailored to the sample's characteristics.
Simplified One-Point Calibration: The HI8733 offers a straightforward one-point calibration procedure using a standard conductivity solution. The easily accessible calibration knob located on the meter's top allows for quick and precise adjustments to ensure accurate readings.
