Hanna Instruments Conductivity Meter: HI 98188

Hanna Conductivity Meter HI 98188The new HI 98188 Conductivity-Resistivity-Salinity Meter has an extended range from ultra pure water 0.001 micro Siemens to very concentrated solutions of 400 milli Siemens.  The meter will also read directly using the mega-ohm scale or in the TDS mode it will read in mg/l or g/l.  To complete the versatility, the meter will also read using a seawater scale.  The display has an optional backlight for greater visibility.  The meter is also designed to exceed USP <645> regulations with modes for Stage 1, 2 and 3.  Log on demand and automatic interval data logging features storage of 400 sample points with time/date stamping.  The USB port allows downloading to a computer with Hanna 92000 software.  Users can then also use Excel to graph data.  The large graphical LCD display will allow storage of user profiles and can display an on-screen help guide showing instructions.   The advanced glass and platinum probe is protected with an Ultem sleeve.  The displayed measurement is auto-ranging, of course.  Automatic calibration can be performed from the keypad at up to five points using seven memorized standards and one or two temperature points.  The reference temperature may be adjusted by the user as well as disabling the automatic temperature compensation.  Rechargeable batteries are installed in a rubberized "military" case which is totally waterproof (IP67).  An inductive charger is included to recharge the installed batteries.  This meter is shipped with a foam padded hard plastic travel case.  We can't heap enough praise on this product.  We have tested it in many different solutions and used the variety of its features. Compared to every other meter we have ever used from any manufacturer, it stands alone.

Another versatile meter we carry is the HI 9835.  It is a work horse which will measure pure DI water and highly concentrated brines without the need for recalibration. 

Other models are the HI 9033, HI 933300 (with printer), HI 99300, HI 99301 and the DIST 7(see below).  While not as full featured as the 9835, they all are waterproof and have useful ranges.  In addition to these, we also have pocket testers such as the DIST 5.

 

HI 9835 Key features:

  • Waterproof case
  • Auto-ranging (meter finds best resolution and scale)portable conductivity meter HI 9835
  • Ranges from 0.01 to 500,000μS/cm
  • Automatic temperature compensation (ATC)
  • Selectable scales:
    • EC (S/cm)
    • TDS (ppm)
    • NaCl
  • Displays both conductivity and temperature
  • ATC may be switched to manual or disabled for actual EC
  • Pushbutton calibration with memorized standards
  • Scalable TDS factor
  • Four ring advanced technology probe w/1m cable included
  • Carrying case included
  • Batteries (4 x 1.5v AA) included
  • Auto-off feature (can be disabled)
  • Weight:  18oz (500g)
  • Dimensions: 7.7" x 3.1" x 2.4"

The top of the line probe used in the above instrument is very important.  The 4-Ring potentiometric design is the most accurate method for conductivity measurement and prevents polarization.  Because it does not suffer from electrolysis it can measure a broader range.  The rings are made from platinum which can resist higher temperatures.  All of the meters we sell use probes of this design.

HI 933300 Data Logging Conductivity Meter with Built-in Printer  

Hanna Instruments Logging Conductivity Meter with Printer

This meter is designed to bring lab grade performance and accuracy anywhere in the plant or even out for field work.  The user can print a permanent, indisputable record of the measured data at any time for record keeping, trouble shooting or compliance purposes. 

The printing interval is selectable from 1-180 minutes.  When the logging mode is activated, the meter records the conductivity and temperature measurements.  These data points can be printed directly or at a later date.  The meter can store up to 8,000 measurements.  The data may also be downloaded to a computer with an optional accessory.

The meter includes a 4-ring technology probe with a built-in temperature sensor, 5 paper rolls, batteries and a rugged carrying case.
