Hanna 9142 Dissolved Oxygen Meter
Hanna 9142 Dissolved Oxygen Meter

The ever increasing demand for instant results for on-site analyzes has created a constant need for waterproof portable meters. The cold, rain, snow and dust associated with use in the field, may damage a meter, rapidly deteriorating its performance and life. HI 9142 is a rugged, water resistant meter that solves the common problems of field use. It is very simple to use: calibration is performed with HI 7040 zero oxygen solution while 100% calibration is done in air. There is no need to use chemical solutions or go through time consuming calibration processes. The polarographic probe (HI 76407/4) will take measurements accurate to 0.2 ppm O2/liter in less than 1 minute and is equipped with a 13' (4m) cable that allows measurements to be taken in even hard to reach places. For applications that require a longer probe cable, the HI 76407/10 probe with a 32.8 foot (10 meter) cable is available. The conic shape of the probe allows it to be used in all BOD5 measurements making it a truly versatile instrument. HI 9142 is supplied complete with an HI 76407/4 D.O. probe, 2 spare membranes, HI 7041S electrolyte solution, 4 x 1.5V AA batteries and instruction manual in a rugged carrying case.

  • Water Resistant Casing - The rugged construction is water resistant, making it indispensable in the biological water treatment industry.
  • One Point Calibration - With the probe in saturated air, the meter can be calibrated without the need for chemical solutions.
  • ATC Circuitry - The meter's built-in Automatic Temperature Compensation circuitry will adjust all readings to provide the utmost accuracy.
  • Low Battery Indicator - The low battery indicator gives the user advanced notice to avoid taking an erroneous reading due to low power.

Hanna 9828 Multiparameter Water Quality Portable Meter
Hanna 9828 Multiparameter Water Quality Portable Meter

The HI 9828 Multiparameter Portable Meter is a comprehensive analytical instrument, capable of measuring up to 13 critical water quality parameters (6 measured and 7 calculated), including pH, EC/TDS, ORP, DO, atmospheric pressure, and temperature. Some of the most advanced capabilities available are incorporated into this portable meter. Designed for intuitive operation, the menu-driven navigation is user-friendly and logical. A backlit 128 x 64 pixels graphic LCD, that automatically sizes the digits, allows full configuration of each measured parameter, displays on-screen graphing and has options for units and language selections, provides high-quality resolution and sophistication that is unsurpassed in its class.

Engineered with smart features such as auto recognition of pH/ORP probe, auto-ranging adjustments for EC/TDS readings, and measurement check - to eliminate erroneous readings - and more, our design actually simplifies operations and handling. There is virtually no learning curve to getting into this meter and quickly mastering it's capabilities. Each parameter is fully supported by the on-screen contextual HELP function, which is active during measurement and calibration modes. For field applications, Hanna's Quick Calibration allows the user to standardize pH, conductivity and dissolved oxygen, all with one solution! While in calibration mode, the meter will also assess and verify probe functionality. For monitoring and recording data, HI 9828 can be equipped with the optional T.I.S. - Tag Identification System: iButton©s with unique ID numbers. Installed at any sampling site, these tags will record and match specific location information with logging data. Comprehensive GLP features, such as last calibration date and status information, calibration time-out, and date and time tags associated with sample measurements, ensure consistency and accountability. The LOGGER function memorizes data from each connected sensors and log-on-demand & automatic logging can record up to 60,000 data samples. All data is downloadable to a PC via USB connectivity.

HI 9828 is designed for demanding outdoor environments. The meter is impact resistant and waterproof to IP67 standards (30 minutes immersion under 1 m of water), and the multi-sensor probe, HI 769828, with an IP68 rating, can be left underwater for an extended period of time. This intelligent probe contains a built-in microprocessor with amplifiers, interprets the high impedance signals from each sensor and sends the converted data to the meter. Consequently, common tolerance issues associated with high impedance signals, such as limiting cable length, and noise interferences are eliminated. The probe maintains reliable communication with the meter, and the user is warned of any problems, such as a broken cable line.

Five out of six measured parameters are housed in the probe: pH/pH mV, ORP, EC, % saturation and mg/L (ppm) oxygen and temperature. Each sensor is independently replaceable, and easy to maintain & clean. The sensors are protected by a rugged outer PVC/stainless steel sleeve, the design of which is suited for use in 2'' wells. The intact probe housing is rated to IP68. Standard cable lengths are 4, 10 and 20 meters and custom lengths are available upon request. The galvanic DO sensor has a built-in thermistor to provide fast temperature corrected readings. Of course, there is no polarization time for this sensor, so it is ready for measurement at a moment's notice. For EC, a 4-ring conductivity system ensures stable readings that are immune to polarization and the buffering effect of surface coating. Absolute conductivity, temperature corrected conductivity, salinity, specific gravity and TDS determinations are possible with measurements from this sensor. The meter automatically recognizes the presence of either the pH or pH/ORP sensor. Both sensors have a cloth junction which allows greater sensitivity, and are gel-filled for improved resistance to contamination. The meter also displays pH/mV readings, ideal for trouble-shooting. It accepts both alkaline and rechargeable batteries and can be recharged in the field via the 12V car accessory outlet adapter, included.

Hanna 991301 Multiparameter Meter
Hanna 991301 Multiparameter Meter

These new waterproof instruments offer pH, conductivity, TDS (Total Dissolved Solids) and temperature readings in one easy to use meter. HI 991300 measures low range conductivity and TDS, while HI 991301 measures high range. Both instruments provide full scale pH readings and allow the user to select the temperature readout in Centigrade or Fahrenheit.

Other features include automatic calibration, automatic temperature compensation, selectable EC/TDS conversion factor, adjustable conductivity temperature coefficient, stability indicator, Battery Error Prevention System and battery strength percentage guage. All functions are accomplished with only two buttons. When the instrument is turned on, % battery power remaining is displayed preventing unexpected battery failures in the field. Calibration is quick and simple at one or two points and the user can select between the instruments’ memorized NIST or standard pH buffers. Conductivity and TDS calibration is also automatic with five programmed values to choose from. Depending on the application, the user can select the conversion factor between conductivity and TDS, as well as the temperature coefficient factor.
