เครื่องวัดความนำไฟฟ้า ความต้านทาน HI2316 HANNA 

Benchtop EC and Resistivity Meter with ATC

The HI2316 is a combination benchtop meter that measures conductivity in four different ranges as well as resistivity. The meter utilizes a four-ring potentiometric conductivity probe with platinum sensors to offer versatility over typical amperometric designs. By utilizing the four-ring probe, it is possible to measure very low or very high conductivity levels without having to change probes. The resistivity probe supplied with the meter requires little maintenance and a built-in temperature sensor. The HI2316 also offers an adjustable temperature coefficient (β) for both EC and resistivity.

Details

The HI2316 is a durable, affordable resistivity and EC meter. The HI2316 comes with a four-ring potentiometric EC probe as well as a resistivity probe, both of which feature built-in temperature sensors. Operation of the meter is simplified to calibration, range selection, and adjustment of the temperature compensation coefficient.

EC and resistivity calibration is made simple through the easy-to-operate front panel knobs for adjustment. A front knob is also provided to manually set the temperature compensation coefficient of both EC and resistivity.

Features at-a-glance

Simple User Interface - Operation is simple with limited features that only require the use of a couple of buttons.  Readings are easy to view on the large, clear display.

Calibration – Manual calibration can be performed at 1 point for both EC and resistivity. Two front panel knobs allow for simple, user-friendly calibration of the HI2316 benchtop meter.

Four-ring EC Probe – The HI2316 meter is supplied with the HI76303 platinum, four-ring EC probe with a built-in temperature sensor. The four-ring technology allows measurement over a wide range from 0.00 μS/cm to 199.9 mS/cm with a full-scale accuracy of ±1%.

Resistivity Probe - The HI3316D resistivity probe is also included with the HI2316 benchtop meter. Specially designed to measure resistivity, the easy to maintain probe features a built-in temperature sensor for accurately compensated resistivity readings.

Temperature Compensation - Temperature is automatically compensated for from 0 to 50°C. The temperature correction coefficient, also referred to as β, is adjustable from 0 to 2.5 %/°C for EC measurements and from 2 to 7 %/°C for resistivity measurements.

Built-in Solution Holders - The HI2316 benchtop meter features four solution holders built directly into the casing. This convenient feature saves valuable benchtop space and maintains solution bottles in an upright position, avoiding any potential spills.
