HI 2300 performs EC, TDS (Total Dissolved Solids), percentage of NaCl and temperature measurements. The auto-ranging feature for EC and TDS measurements automatically sets the resolution suitable to the tested sample.
All measurements can be temperature compensated at 20 or 25°C and the compensation coefficient is selectable by the user. The automatic temperature compensation can also be disabled for measuring the actual conductivity value. The stability indicator on the LCD ensures accuracy.
Conductivity readings are performed by applying an alternate current to the 4-ring probe which creates a variable voltage directy proportional to conductivity.
The GLP feature allows users to store and recall data about system status.

A ph electrode that is properly manufactured and kept clean will retain its measuring integrity for quite a long time.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned industrial electrode. This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration.
manufacturer of ph meters on the market today will allow an offset of approximately ±60 mV. The deviation from 0 mV is not unusual, in fact it represents the true characteristics of the pH electrode. The deviation from 0 mV becomes a problem if it is the result of calibrating a dirty electrode.
HANNA instruments' HI 221 & HI 223 compare the characteristics of the pH electrode from one calibration to the next. In case of large variances in the electrode condition that can only be the result of a soiled sensor, these meters alert the user that the electrode needs to be properly cleaned prior to calibration and measuring.

| The Verimet® M4900C is especially well-suited for measuring the conductivity of aluminum and aluminum alloys. It tracks the temperature coefficient (typically aluminum) using a single-knob control to adjust the readings. Compensation is accurate to 0.5% I.A.C.S. over the full range of 12% to 110% I.A.C.S. (5.75% to 52.8% MegaSiemens). The M4900C has an accuracy of 0.3% over the aluminum range of 30% to 62% I.A.C.S. The Verimet® M4900C professional tester works well on rough or finished surfaces, including forgings, castings, sheet stock and small parts of reasonable mass. Penetration depth is constant, irrespective of material or conductivity. |
