9 Meter Lab 845
9.1 Areas of use
The pH/ORP/ISE meter is used to determine the pH value, the voltage as well as the temperature.
The meter simultaneously measures the pH value, the voltage and the temperature. The Lab845
combines the advantages of a compact design with the precision and comfort of a lab meter with a
high measuring accuracy, multi-function display, integrated data logger and a robust aluminum
housing.
9.2 Basic model
The basic model of the meter includes a pH sensor. This combination meets the requirements to
determine the pH value; electro-chemical process as per EN ISO 10523:2012. The meter can be used
wherever you want to measure pH values, ORP potentials or ISE concentrations as well as
temperature quickly and precisely. High measuring accuracy, processor-controlled measured value
processing and the versatility in connection with pH, ORP or ISE measuring chains mark the Lab845.
It is equipped with automatic temperature compensation for pH measurement as well as an adjustable
reference temperature for measurements taken without a temperature sensor. In addition to the value
input, an automatic as well as a manual calibration routine is available to calibrate the meter. If an
ORP single rod measuring chain is connected, the temperature-compensated and calculated ORP
potential with reference to the standard hydrogen electrode as per DIN 38404 is displayed in addition
to the measured ORP potential.
9.3 pH sensor
The description of the used pH electrode is listed in the separate instructions for use for the sensor.
