Zoom

The most important features

• Very high accuracy meter for use in the field and laboratory.
• Measures pH, redox potential (ORP) and temperature.
• Simultaneous observation of all the chosen functions results on the colour touch sreen.
• Calibration in 1 to 5 points.
• In the pH function automatic correction of the pH standard solution value changes, along with the temperature changes for NIST standards.
• Memory of 2 000 data sets.
• USB output.
• Waterproof housing.
• Small size and weight.

Detailed description

Characteristic features:

• The meter is designed for highly accurate measurements of : pH, redox potential and temperature.
• It may be used for the field measurements as well as during accurate laboratory work.
• Low weight and small size make working in the field easier.
• Waterproof housing (IP-66) enables working in difficult conditions.
• ”HOLD” function to freeze the result on the display.
• Signalisation of the result stabilisation with the ”READY” symbol and a sound.
• Possibility of sending a calibration report to a PC - up to 10 last calibrations.
• Depending on the kind of applied electrode it may be used for clean water, sewage, soil, pastes, paints, cheese, milk, meat measurements etc.
• Calibration of the pH electrode in 1 ÷ 5 points.
• Automatic detection of buffer solutions, their values may be set by the user.
• Automatic correction of the pH standard solutions values changes along with the temperature changes for NIST standards, what eliminates the necessity of warming up or cooling them down.
• Automatic or manual temperature compensation.
• Possibility of storing characteristics of 3 pH electrodes enables their quick replacing - very useful feature during field work.
• Automatic control of the electrode’s condition.
• Easy readout of the electrode's parameters (buffer and slope).
• Precise redox potential measurement (accuracy 0.1 mV).
• Possibility of mV measurement in relation to the set or measured reference potential – Vref.
• Memory of 3 different temperature sensors parameters.
• It is possible to enter the group of selected temperature sensor what increases the measurement accuracy.

Other features:

• Internal clock with date.
• Collecting up to 2000 data sets in the internal datalogger with temperature, time and date, single collecting and also taking series of measurements possible.
• Non-volatile memory of the stored results and calibration data.
• Storing the date of next calibration.
• Possibility of choosing the language: Polish, English or German.
• Possibility of connecting with a PC by a micro USB output.
• Powered by rechargeable batteries or power adapter with USB - micro USB cable.
• The rechargeable batteries are charged internally.
• Continuous work time without charging up to 18 hours depending on the chosen brightness of the screen.
• Meets the GLP requirements.
• 24 months of warranty for the meter.
