HANNA HI 23151-01

The HI 23151 Bench-Top Multi-Range Conductivity Meter is a multi-range meter with built-in automatic temperature compensation for Conductivity measurements. The HI 23151 replaces EC 215R and features a large, easy to read LCD, solution holders and an attractive redesigned case.

The HI 23151 utilizes a four ring potentiometric probe with platinum sensor that offers greater versatility and accuracy over typical amperometric designs. A potentiometric probe works on the principal of induction which eliminates the effects of polarization ( a common problem of amperometric systems) . Two outer rings apply an alternating voltage and induce a current loop in the solution while two inner rings measure the voltage drop induced by the current loop ( which is dependent on the conductivity of the solution) . By utilizing the 4-ring method, it is possible to measure very low to high conductivity levels ( up to 200 mS/ cm) without changing probes.

The temperature coefficient correction is adjustable from 0 and 2.5% / ° C.

FEATURES/ BENEFITS:
* Four ring potentiometric platinum probe
* Four measurement ranges
* ± 1% F.s. accuracy
* Manual calibration
* Analog output
* Automatic Temperature Compensation
* Large LCD
* Built-in Solution Holders

FEATURES IN DEPTH:
Four ring probe – This allows for 1 probe to measure 4 ranges with no polarization effect. It provides an increased accuracy ( 1% F.S.) over amperometric style meters.

Analog output – Allows a recording device to be connected to the meter.

Manual calibration – This simple to use feature allows the HI2315 Bench-Top Conductivity Meter to be calibrated to any value within the measurement ranges ( 0.0 to 199.9 µ s/ cm; 0 to 1999 µ s/ cm; 0.00 to 19.99 ms/ cm; 0.0 to 199.9 ms/ cm) It is also less expensive than models with auto-calibration.

Manual adjustable temperature correction coefficient ( ß = Beta) – This simple to use feature allows for different temperature correction coefficients to be used based on the sample being tested. It is adjustable from 0-2.5% / ° C.

Automatic Temperature Compensation – This helps provide the HI 23151 with higher accuracy since conductivity is very sensitive to temperature variations.

Large LCD – The new, larger LCD is bright and easy to read.

Built-in Solution Holders – The HI 23151 has solution holders built into the casing. This convenient feature saves space and prevents solutions from tipping over.

Recessed Connector Bay – Protects connectors from liquids.
