PORTABLE pH-METER - THERMOMETER - DATA-LOGGER

The instrument measures pH, mV and tempe-rature. It is able to take and store up to 26,000 readings (256 Kb), and gives the maximum, minimum and mean value. The rhythm of data acquisition may range from one reading per second to a maximum of one every 12 hours. The stored data may afterwards be sent directly to a printer, with serial input, or a computer, with indication of the date, hours and minutes. The instrument has a serial output which is insulated and bidirectional; the baud rate may be configured from 300 to 19200 baud. All types of electrode for pH measurement, electrodes for measuring the redox potential (ORP) or specific ion electrodes (ISE) may be connected to the BNC connector at input A. Probes of the TP 870 series for measuring temperature may be connected to the DIN 8- pole connector at input B or probe Pt100 4 wire. The double indication of the LCD and a wide range of symbols make the portable instrument DO 9505 extremely versatile and easy to use, despite the many functions that it offers. The typical field of application is for measuring pH, mV and temperature on the field, in springs, artificial lakes, canals, water purifying plants, industrial systems, fishbreeding establishments, greenhouses, laboratories and wherever there is a need to know accurately and store pH and redox measurements or measurements with a specific ion electrode.
Instrument functions:
AUTO POWER OFF, HOLD, low battery indication, data acquisition and storing, storing of the maximum, minimum and mean value, manual or automatic calibration using known buffer solutions.
