Bench top pH Meters Product Description
The ProLab 1000 professional bench top pH meters were designed to perfectly match SI Analytics world class pH electrodes.  With a measuring range from -2.000 to +20.000 pH and an accuracy of 0.003 pH the professional bench top pH meter is especially suited for demanding measurements in a research laboratory or process control lab.

Bench top pH meter electrode calibration check
The ProLab 1000 bench top pH meters achieve their accuracy by using a feature called CalClock.  The CalClock feature provides the bench top pH meters with a unique combination of sensor evaluation and a calibration timer which controls all relevant calibration settings.  The bench top pH meter's sensor evaluation displays the pH electrode's quality in increments.  The bench top pH meters monitor the pH electrode's slope, zero point, and reaction time.  The selected calibration interval is displayed by the bench top pH meter as a countdown in six steps as a set of circular segments around the pH electrode which elapse proportionally to the calibration interval.  When the time interval has elapsed the bench top pH meter activates an optical and acoustic signal.  The bench top pH meter's automatic calibration of up to 5 points and automatic buffer recognition of 22 buffer sets guarantee trustworthy pH measurement results of the highest quality.  The user can employ his preferred buffers on the bench top pH meters the same comfortable way as the SI Analytics DIN buffers and thus easily comply with the users specific SOP requirements.  During the calibration process the bench top pH meter can display either the buffer pH or the current mV value.  The slope can be displayed in either % of in mv/pH and the asymmetry reading in mV or pH on the bench top pH meter's display screen.

Bench top pH meter sensor and user recognition
The bench top pH meter's wireless sensor recognition and user identification features mean that every stored measurement can be assigned an electrode and user ID.  The bench top pH meter reads the pH electrode's individual data (slope, zero point, ID number, and date of last calibration) directly from the special ID sensor.  The ID sensor stores all new calibration data every time the sensor is re-calibrated thereby assuring that only the most recent data is used by the bench top pH meter for calculation of the measured value.  No additional cables are required for the bench top pH meter to use the special ID feature, as the transponder is mounted in the sensor's plug.  This means that even when using multiple ID-electrodes on the same bench top pH meter, the correct calibration data is always chosen automatically.  The ID recognition process is performed automatically by the bench top pH meters and does not require any manual settings.  If sensors without the special ID function are used with the bench top pH meters the sensor values are stored in the instrument, so existing sensors can be used without any issues.

The ProLab 1000 professional bench top pH meters also comply with further requirements by allowing you to set administrator rights or setting up user identification via an electronic ID card.  A special key ring pendant with a transponder is utilized as an "ID card" to identify registered users with the bench top pH meter.  The pendant only needs to be placed onto the recognition field on the upper side of the bench top pH meter.  The transponder stores an individual 12 digit number that is read by the bench top pH meter and assigned to each measurement and calibration.  The bench top pH meter runs the entire process automatically in the background and doesn't require any user settings.  Measurements and calibrations performed without prior user recognition are labeled by the bench top pH meter as "anonymous" and can be sorted accordingly.  Additionally, the bench top pH meter's sensor recognition records the pH electrode used by the individual user.

Bench top pH meter case
With a timeless, classy design the professional bench top pH meter's case reflects the top quality rating of the ProLab instruments.  Housed in a solid metal body the bench top pH meter's big and brilliant graphic display is protected by a one piece glass slide.  The backlit high resolution display shows you both the bench top pH meter's pH measurement and the current temperature with outstanding legibility minimizing reading errors.  The bench top pH meter's weight of approximately 5 1/2 pounds (2.5 kg) guarantees a firm base.  With an IP 54 rating the bench top pH meter electronics are completely sealed against dust and water splashes from all sides.  The chemically resistant design also makes the ProLab bench top pH meters easy to clean and disinfect.  The S4D stand can be attached without tools either to the left or the right side of the bench top pH meter to create an immovable unit.  The three hinged construction of the bench top pH meter's arm was designed for maximum comfort during sample measurement and holding the electrode into the sample beaker.

Bench top pH meter data functions
The bench top pH meters calibration protocols comply with GLP requirements.  The last ten calibrations along with 1500 date, time, and ID stamped measurement results can be recalled from the bench top pH meter's memory.  The data can be stored on the bench top pH meters in seven selectable intervals from 1 second to 60 minutes.  All data is stored by the bench top pH meter according to 21 CFR Part 11 in hierarchy levels with user identification.  Whether conventional via RS 232 or modern via USB - both PC interfaces are integrated in the ProLab 1000 professional bench top pH meters.  No adapters are required to interface the bench top pH meters to your PC.

Other bench top pH meter functions
The bench top pH meters have an integrated stability control feature which checks the measured value's stability.  The measured value is only released when certain stability criteria is reached by the bench top pH meter.  The criterion is adapted to SI Analytics electrodes to achieve the best compromise between accuracy and speed of measurement on the bench top pH meter.  This prevents the bench top pH meter from making measurement errors due to premature readings of unstable values.  The bench top pH meter's stability control feature is automatically activated for all sensor calibrations.  For measurements the bench top pH meters' stability control feature can be switched on or off.  The bench top pH meters also feature an integrated dead stop function which allows for applications requiring manual titration such as the wine and food industry.  The bench top pH meters can also accept ISE measurements with a measuring range from 0.000 to 999,999 mg/l using a 2 to 5 point calibration with standards from 0.000 to 500,000 mg/l.  Complete IQ and OQ documentation is available for the bench top pH meters.

Bench top pH meter applications
The ProLab 1000 bench top pH meter is ideally suited for a wide range of applications in chemistry, pharmacy, biotechnology, and food industry labs.
