Consisting of: pH-mV-temperature measuring instrument/combined electrode with integrated temperature
sensor pH/T30. Set of buffer solutions 3 x 100 ml of pH 4/7/10 and 100 ml 3mol KCL solutions, all well arranged in WinLab Profi-Box with integrated electrode stand for more comfortable measurements and calibration. Incl. manual booklet.
Technical features
Simultaneous pH or mV and temperature indication
Automatic sensor identification for temperature sensorPTC, Pt100, NTC 30 k , the sensor type is indicated in the display
Extra input for temperature measurement
a) for PTC sensor with 5 m or 10 m cable for deep-water temperature measurements
b) for Pt 100 for exact measurements across a large measurement range from -100to 400gradeC Electrode faults are identified and indicated immediately Calibration is performed automatically for 2 buffer values and three different buffer solutions (WinLab, NBS or other)
The last calibration is indicated with the date in the display (acc. to GLP) Optical alarm for the next due calibration
The data logger
Equipped as standard for 250 measurement data complete with indication of the measurement value, the measurement variable, the measurement point and date WinLab starts measurements automatically at the required time; serial measurements are easy to take(max. 250 measurements)
With RS 232 C interface for transferring the data to a PC
The case
Extremely tough, impact-resistant, dust-proof and water-proof (protection type IP 66and IP 67) for harsh conditions
The display
Is (14 mm high) very good to read, with the indication of the measurement variable and a parallel temperature reading. Other items of information displayed: electrode condition, electrode faults, calibration intervals, calibration faults, date, time, type of buffer solution, etc. WinLab Profi-Box with integrated stand for calibrations and measurements. An intermediate cover provides an additional work top, with easy-to-clean deep-drawn inserts made of tough polypropylene.
