เครื่องวัดความเค็ม HI931101 HANNA

Sodium Content and Activity Portable Meter

The HI931101 is a rugged, waterproof, portable sodium content meter. This meter offers many features including automatic calibration, automatic temperature compensation, and on-screen instructions. There are four measurement ranges for sodium content, and a simple press of the MODE button allows for measurement of sodium ion activity. The HI931101 is supplied complete with meter, glass body sodium ion selective electrode (ISE), and temperature probe packaged in a durable carrying case.

Details

The HI931101 is a rugged, portable sodium content and activity meter designed to provide laboratory precision and accuracy under harsh conditions. This meter is ideal for a variety of applications in laboratories, food and beverage production, and water quality analysis.The HI931101 offers a variety of features including five distinct measurement ranges, automatic calibration to 1 or 2 points, temperature compensation, and on-screen instructions.

The HI931101 uses a BNC probe input for connecting the sodium ISE and a separate RCA connector for a thermistor temperature probe. The temperature probe provides for a high ±0.2 oC accuracy measurement for precise temperature readings.

Features at-a-glance

One or Two-Point Calibration - Automatic calibration can be performed at 1 or 2 points with a choice of 3 buffers (0.23 g/L, 2.3 g/L, and 23.0 g/L). For greater accuracy, standard solutions should be calibrated at a temperature as close as possible to the temperature of the sample.

On-Screen Instructions - Clear and easy to use on-screen instructions take you through all of the steps in performing a calibration and taking measurements.

Sodium Ion Selective Electrode - The HI931101 is supplied with the FC300B sodium ion selective electrode, comprising a glass body and sodium sensitive membrane. The sodium sensitive membrane should be conditioned before performing a calibration. The conditioning of the electrode is a two-step process in which the glass is etched then rehydrated. Etching removes a thin layer of sensitive glass from the sodium membrane, exposing a sodium-containing fresh surface. Rehydrating after etching provides optimum conditions for the exchange of sodium ions between the membrane and solution.

Fixed Temperature Compensation - The HI931101 offers fixed temperature compensation of sodium measurements at 25°C.
