We are very excited about the new Cal-Check Portable HI 9126--- a great waterproof pH meter.  We use this pH meter for field verifications.  The 9126 is the next generation of the field proven model HI 9025 that has been the "gold standard" for so many years.

This pH meter has the ability to calibrate automatically using the standard pH buffers and one custom (user defined) buffers to take advantage our any of the "technical" special buffers which cover the entire pH range.  (see accessories in this pH section).  It also has an option to use a back lighted display for low light environments.

The Cal-check feature shows the condition of the electrode using a bar graph in the lower left of the display.  Read more about Cal-check in the "technical info" section of this website.

This meter includes a hard plastic travel case, pH electrode, temperature sensor, AA batteries, buffers and instruction manual. Click on picture for more information and specifications.

Field Monitoring Meters for pH, ORP and ISE: HI 9817x

And now, the 9026 has some big brothers: Introducing the field monitoring Calibration Check Meters: HI 98170 / HI 98171 / HI 98172.  These pH meters feature rechargeable batteries with an inductive recharger.  The battery life is about 200 hours for long operation in the field.  But when the batteries are low,  simply put the meter in Hanna's inductive recharger cradle for a few hours and you are ready to go.  And to make life even better, the recharger can be powered from a car 12 volt outlet or with the included 115V adaptor.    Advanced Calibration Check Portable Meters

While the rechargeable feature is nice, the real story about this trio of meters are the powerful analytical assets: GLP, pH/ORP/ISE measurements, ATC, auto-calibration at up to five points including custom buffer values (user configured) plus seven standard values, backlit display,  log on demand, RS-232 interface and of course the Hanna calibration check 5 bar graphic indicator which determines the electrode condition.  Depending upon which model is selected, the user can use a variety of electrodes such as: pH, ORP, Fluoride, Sodium, and other ISE's.

The HI 99121 kit has been designed to address the question of correct and rapid measurement of pH directly in soil. Every item in this kit has been made to facilitate measurements in the field without compromising accuracy. With HI 99121 you can test the pH of soil directly or after preparation of a diluted sample. In order to measure the pH directly, the kit includes a plastic auger to perforate the ground. The HI 1292D pH electrode has been designed for direct soil measurement. It has a conic, rugged tip and can be directly inserted in moist or soft soil. The electrode incorporates a temperature sensor right near the tip to enable it to measure and compensate for the temperature quickly. For higher degrees of accuracy, or for stony ground where the electrode may be damaged, use the specially made HI 7051M soil preparation solution. This solution is included in the package to help you measure pH more precisely by diluting a sample of the soil in it. The dual-level LCD shows the pH value from -2 to 16 with 0.01 resolution. It also displays the temperature on the secondary level at the same time. With a menu-driven custom microprocessor, the user is helped with clear prompts during operation and calibration.

HI 9210N is supplied with a rugged pH electrode which, in addition to the pH reference system and sensitive bulb, incorporates a temperature sensor and a miniaturized amplifier. You need to use only one probe for both measurements! The electrode signal is also pre-amplified and strengthened to give you better protection against noise and electromagnetic interference, a common phenomenon in industrial applications. Calibration is manual and the trimmers are placed behind a protective cover. This assures that the unit can be calibrated at any pH buffer value. The protective cover also keeps the meter watertight and prevents the calibration from being tampered with. Even though the HI 9210Ns battery life is an incredible 2000 hours, a low voltage indicator appears on the screen to alert the user that there is only 20 hours of battery life left. Afterwards, the BEPS (Battery Error Prevention System) will stop any false readings by shutting the meter off.

HI 9210N is supplied complete with HI 1217D gel-filled combination pH/C electrode, and 1 m (3.3') DIN cable, 4 x 1.5V AA batteries and instruction manual.

Measures pH & ORP with one probe

$350
 

Portable pH Meter with Sensor Check
 
  • Ideal for Water Plating baths, potable water  & Swimming Pools
  • 4-in-1 Probe (pH, ORP, pH/mV & temperature)
  • Sensor Check Feature


HI 991003 is the first pH meter that can measure pH, pH-mV (to check the electrode status), ORP and temperature with only one probe. Since ORP measurements are strongly affected by pH level, HANNA instruments has developed the first meter that simultaneously measures both ranges. With all other instruments you need to switch the pH electrode with an ORP electrode (or vice-versa) and, therefore, it is impossible to have both measurements at the same time. HI 991003 is largely used to control plating bath waste water, swimming pool water quality and potable water sanitizing processes. HI 991003 is provided with our unique Sensor Check feature that allows the user to establish the status of the pH electrode before performing measurements. The Sensor Check feature consists of a pH-mV scale that shows the characteristics (slope and offset) of the sensor, allowing the user to determine if the electrode is in good condition. HI 991003 is protected in a waterproof casing for use in humid and wet environments. It also features a large duallevel LCD that displays pH or ORP and temperature readings simultaneously.

HI 991003 is supplied complete with HI 1297D pH/ORP electrode with internal temperature sensor, pH 4 and pH 7 buffer sachets, HI 700661 electrode cleaning solution (2 x 20 mL), batteries, rugged carrying case and instructions.

Flat tip probe for surface measurements
 
Leather & Paper pH Meter
 
  • Important for Production & Packaging
  • Quick & Easy Measurements
  • Flat Tip Probe Designed for Surface Contact


Direct measurement of pH on paper and leather is made fast and easy with the HI 99171 pH meter provided with a flat tip probe, specially designed to optimize surface contact with the sample. pH measurement of papers and cartons is important, not only in the production phase, but also in the packaging phase. The food industry, for example, performs many compatibility tests; one of these is pH. Measurements are automatically compensated for the effects of temperature with the internal sensor of the probe and the LCD continuously displays the sample's temperature. All operations can be performed simply with 2 buttons; messages and symbols on the display guide the user through each measurement and calibration procedures. pH and temperature ranges are extended, from -2.00 to 16.00 pH and -5.0 to 105.0 C respectively. Calibration is automatic at 1 or 2 points, selectable by the user between 2 memorized buffer sets. Battery life is more than 1500 hours and the percentage of the remaining charge is displayed when the meter is turned on. HI 99171 turns off automatically after 8 minutes of inactivity.

HI 99171 is supplied with HI 1414D pH electrode, pH 4 and pH 7 buffer sachets, HI 700680 cleaning solution (2 x 20 mL sachet), HI 70960 sample preparation solution (30 mL), batteries, rugged carrying case and instructions.
