• HI 98321; EC - 0 to 3999 µS/cm; TDS - 0 to 2000 ppm
• HI 98322; EC - 0.00 to 20.00 mS/cm; TDS - 0.00 to 10.00 ppt

HI 98321 & HI 98322 are supplied complete with 4 x 1.5V batteries and instructions.

HI 9835 Waterproof, Autoranging, EC/TDS/NaCl/°C Meter Professional Extensive conductivity and TDS/EC range with the resolution automatically selected by the meter without pressing any key. Both conductivity (or TDS or NaCl) and temperature are displayed at at the same time. User Friendly Large LCD with helpful graphic symbols and low battery warning. User replaceable probe. Easy calibration procedure with memorized values. Design & Construction Rugged lightweight ABS material, large tactile rubber keys , PVC probe for best field protection, stable on workbenches, lab desktops or slippery surfaces. Just One Probe HI 76309 measures any kind of sample from dionized water to brine with Automatic Temperature Compensation without requiring recalibration. Order Information Specifications

The Hanna HI 9835 can measure conductivity, total dissolved solids, NaCl, and temperature, all with one probe. The temperature of all conductivity and TDS measurements is automatically or manually compensated for by the meter's ATC circuitry. The temperature coefficient is user selectable from 0.00 to 6.00 %/°C (for EC and TDS only) and the TDS factor can be set from 0.40 to 0.80.

The meter is constructed with a waterproof, rugged housing which allows the versatility required for both laboratory and field use. Moreover, HI 9835 is equipped with a large LCD that helps the user through operation and calibration with large comprehensive symbols. Besides displaying the measurements, the LCD simultaneously displays the temperature. The display gives a low battery warning and switches itself off after 5 minutes of non-use to save the batteries.

HI 9835 is supplied complete with HI 76309 Conductivity/TDS probe with 3.3' (1 m) screened cable, AA size Alkaline Batteries (4 pcs) and instruction manual in a rugged carrying case.

	HI 9932 Autoranging Bench EC/TDS/NaCl/°C Meter Automatic Buffer Recognition User Adjustable Controls The user can adjust the TDS factor in addition to the temperature coefficient. Dual Level Display The large Liquid Crystal Display will simultaneously show temperature and one other parameter. RS232 port Serial interface through the meter's RS232 port will allow data transfer to a PC. Order Information Specifications

HI 9932 is the most technologically advanced bench-top conductivity meter on the market. In addition to the wide range of Conductivity, this meter will measure Total Dissolved Solids, NaCl and temperature. The autoranging feature of the EC and TDS ranges automatically sets the meter to the scale with the highest possible resolution. Measurements can be automatically (ATC) or manually (MTC) compensated for temperature and the temperature coefficient value is user selectable. It is also possible to disable the temperature compensation and measure the actual conductivity. The meter is equipped with a stability indicator. HI 9932 also features GLP capability and allows transfer of data to a computer through an RS232 port. In addition, the meter allows the user to enter an ID code to uniquely identify the instrument.

Conductivity Range: 6 different ranges: 00.0 to 29.99 µS/cm, 30.0 to 299.9 µS/cm, 300 to 2999 µS/cm, 3.00 to 29.99 mS/cm, 30.0 to 200.0 mS/cm. Up to 500.0 mS/cm actual (*) Conductivity. The temperature coefficient is user selectable from 0.00 to 6.00 %.

Total Dissolved Solids: TDS factor can be adjusted from 0.40 to 0.80 (default value is 0.50). TDS ranges are: 0.00 to 14.99 ppm,15.0 to 149.9 ppm,150 to 1499 ppm,1.50 to 14.99 g/L,15.0 to 100.0 g/L and up to 400.0 g/L actual (*) TDS (with 0.80 factor).

Order Information Specifications

HI 99161’s waterproof casing provides excellent protection from water and humidity typically present in the food industry. HI 99161 comes supplied with the FC 202D pH electrode with built-in temperature sensor specially designed for use in the food sector. This electrode features a rugged, easy to clean, Kynar® body that tapers to a strong conic tip ideal for measurements in semisolids such as meats and cheeses. The electrode has a free diffusion sleeve type reference junction which prevents the typical problems of clogging in viscous liquids or samples with high solids content such as milk or condiments. The reference electrolyte used in the FC 202D is free from the poisonous silver chloride which prevents food contamination by the electrode. HI 99161 allows push button calibration at either NIST or standard buffer sets with auto recognition and a stability indicator. The temperature is always displayed on the secondary level of the large LCD.
