อุปกรณ์วัด Conductivity/TDS (Bench-Top EC and Resistivity Meter)
Bench-Top EC and Resistivity Meter
The HI 2316 Bench-Top EC and Resistivity Meter is a combination bench meter that can measure conductivity in four different ranges and resistivity for testing. The HI 2316 replaces HI 216 and features a larger, easy to read LCD, solution holders and an attractive redesigned case.
The HI 2316 utilizes a platinum four ring probe with a built-in temperature sensor that automatically compensates for temperature variations. The temperature coefficient can be adjusted from 0 to 2.5% by also using a knob on the front panel.
For resistivity measurements, the meter is factory calibrated and if necessary, calibration can be adjusted. It also features a built-in temperature sensor for automatic temperature compensation and the temperature coefficient is user selectable from 2 to 7%.

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.
Resistivity probe – This specially designed probe measures resistivity and contains an internal temperature sensor.
Manual calibration – This simple to use feature allows the HI 2316 Bench-Top EC and Resistivity Meter to be calibrated to any value within the measurement ranges. It is also less expensive than models with auto-calibration
Automatic Temperature Compensation – This helps provide the HI 2316 with higher accuracy since EC and Resistivity measurements are very sensitive to temperature variations.
Large LCD – The new, larger LCD is bright and easy to read.
Built-in Solution Holders – The HI 2316 has solution holders built into the casing. This convenient feature saves space and prevents solutions from tipping over and spilling.
Recessed Connector Bay – Protects connectors from liquids.
* Municipal drinking water, environmental studies
* Water Treatment – Boiler/Cooling Tower water quality
* Agriculture – Fertilizer concentration
* Food processing – salt levels in food. (i.e. making pickles)
* High Purity Water
* Printing industry – fountain solutions
* Plating – Chemical concentration in plating baths
