HANNA HI2315 Conductivity Benchtop Meter

The HI 2315 Bench-Top Conductivity Meter is a multi-range meter with built-in automatic temperature compensation for testing Conductivity. The HI 2315 replaces EC 215 and features a large, easy to read LCD,
solution holders and an attractive redesigned case.

The HI 2315 utilizes a four ring potentiometric probe with platinum sensor that offers greater versatility and accuracy over 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.

FEATURES/BENEFITS
* Four ring potentiometric platinum probe
* Four measurement ranges 
* ±1% F.s. accuracy
* Manual calibration
* 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.
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 µs/cm; 0 to 1999 µs/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 2315 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 2315 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.
