Zoom

The most important features:

• Very high accuracy meter for use in the field and laboratory.
• Measures dissolved oxygen in % or mg/l, atmospheric pressure and temperature.
• Cooperates with optical oxygen sensor
• Backlit display enables observation of the chosen function and temperature.
• Calibration in 1 or 2 points (0 and 100%).
• Possibility of entering the known salinity value which influences the dissolved oxygen concentration measured in mg/l.
• Memory of 4 000 results.
• USB output.
• Small size and weight.
• Waterproof housing.
• Meets the GLP requirements.

Detailed description:

Characteristic features of the optical sensor:

• Immediate readiness for work.
• No electrolyte.
• No membrane.
• The sensor does not use up the oxygen.
• Does not require flow of the measured liquid.
• Fast reaction time.
• In case of standard measurements calibration is unnecessary.
• Resistant to optical and chemical interference.
• The drift per year is insignificant.
• Long-lasting work without changing the luminescent cap (8000 h).

Characterstic features of the meter:

• Low weight and small size make working in the field easier.
• Waterproof housing facilitates working in difficult conditions.
• Equipped with easy-to-read backlit display with brightness control.
• Automatic air pressure measurement with calculation of its influence on the result of measurement of oxygen content in water or sewage in mg/l.
• Possibility of introducing the salinity value with automatic calculation of its influence on the result of measurement of oxygen content in water or sewage in mg/l.
• “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.
• When properly handled, the sensor may be efficient for several years.
• 1 or 2 point oxygen sensor calibration.
• Automatic temperature compensation.
• Clock with date.
• Internal datalogger enables storing up to 4000 sets of results, taken in series or singly with temperature, time and date.
• The results and calibration data are stored in non-volatile memory.
• Storing the next calibration date.
• Possibility of connecting with a PC by micro USB connector.
• Change of the date protected by a password
• The data transmission software enables printout of the data in a form protected against any changes.
• Powered by rechargeable batteries or power adapter with USB cable.
• The meter meets the GLP requirements.
• 24 months of warranty for the meter.
• Affordable price.
