A ph electrode that is properly manufactured and kept clean will retain its measuring integrity for quite a long time.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned industrial electrode. This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration.
manufacturer of ph meters on the market today will allow an offset of approximately ±60 mV. The deviation from 0 mV is not unusual, in fact it represents the true characteristics of the pH electrode. The deviation from 0 mV becomes a problem if it is the result of calibrating a dirty electrode.
HANNA instruments' HI 221 & HI 223 compare the characteristics of the pH electrode from one calibration to the next. In case of large variances in the electrode condition that can only be the result of a soiled sensor, these meters alert the user that the electrode needs to be properly cleaned prior to calibration and measuring.

HI 4222 is a dual-channel, research-grade laboratory pH Bench Meter with a backlit 240 x 320 dot-matrix color screen and millesimal measuring resolution. Features include auto-logging and real-time graphic monitors, auto-end point mode and a fully customizable SETUP button. This unit allows for automatic (ATC) or manual (MTC) temperature compensation.
For accountability, on-screen GLP data capture contains calibration information, including buffer values and expiration date, concurrent with measurement readings and logged graph data. For ISE measurements, an ionic strength constant value is stored with GLP data. During ISE Mode, the user has a choice of several incremental methods. With the option to choose up to 5 calibration points for pH - selected from a list of 5 custom and 8 memorized buffers - the system can be fitted to any desired measuring range.
Our exclusive Calibration Check™ diagnostics system determines the quality and condition of the industrial electrode and buffer groups during calibration, and keeps you informed. An enhanced warning system, with acoustic signals, alerts the user when measuring is outside of the calibration range. This system also reminds the user when a new calibration is due, or when the wrong buffer is being employed during calibration. This unit can be given a unique ID number.

HI 991003 is the first supplier of ph meter that can measure pH, pH-mV (to check the industrial electrode status), ORP and temperature with only one probe.
Since ORP measurements are strongly effected by pH levels, 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 vise-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 dual-level LCD that professional displays pH or ORP and temperature readings simultaneously.

Precise measurement is a product of the optimal interaction between industrial electrode, calibration and meter. The obvious next step for us has been to develop meters to perfectly match our electrodes and buffer solutions. The result: The new Lab series of pH and conductivity measuring instruments from SCHOTT Instruments. These instruments are setting new standards for electrochemical measurement.
ph measuring instrument Lab 850
The Lab 850, our “starter” model in the new series, comes with the advanced measuring algorithm specially adapted to SCHOTT Instruments’ electrodes. The result is a calibration and measurement in usual precision – but in a much shorter time!
pH-meter Lab 860 and conductivity meter Lab 960
Whether conventional via RS232 or modern via USB slave – both interfaces to the PC are integrated in the Lab 860 and Lab 960. No adapter is required.
pH–meter Lab 870 and conductivity meter Lab 970
The quality controller’s dream: A measuring instrument automatically recognizes the electrode! The new detection with unique identification send their specific data to the measuring instrument … wireless! Thus the Lab 870 and Lab 970 always use the correct calibration for the identified sensor and help you to avoid errors in measurement. |

SCHOTT Instruments introduces the new laboratory measuring instruments ProLab 3000 (2-channel pH and ISE measuring) and ProLab 4000 (additional Conductivity measuring). The adaptable display comprising the Windows menu structure and the mouse handling are the outstanding convenient features.
Operate the new ProLabs like a PC: You have a 300 MHz processor and a storage volume of 32 MB flash and 32 MB RAM. On a brilliant QVGA colour graphic viewer (320 x 240 pixels) the operation is handled via a Windows comparable menu structure. The display of all measuring values can be configured in the same manner as on a PC. Operate by using the numeric key pad on either of the ProLabs or using an external professional keyboard or optionally use the mouse, which is part of the scope of delivery.
Mouse and keyboard can be operated at the same time. Also memory stick, USB hard disks, professional printer and barcode readers can be connected without any additional configuration. Besides the USB host both instruments also feature a USB slave and a RS232 interface.
The automatic electrode and user recognition known with former Lab- and ProLab instruments is also installed in the ProLab 3000 and ProLab 4000. The same is true for the extensive calibration support features, e.g. the CalClock (parallel display of sensor evaluation and calibration intervals) or the choice of 22 pre-set buffers. The calibration is now improved by the VariCal, enabling the usage of further buffers.
