Elmetron CO401 zuurstofmeter

The most important features:

• Very high accuracy meter for use in the field and laboratory.
• Measures dissolved oxygen in % or mg/l, oxygen in the air in %, atmospheric pressure and temperature.
• 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.

• Characteristic features:

• Low weight and small size make working in the field easier.
• Waterproof housing facilitates working in difficult conditions.
• Equipped with easy to read backlit LCD 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 on the result of measurement of oxygen content in water or sewage in mg/l.
• In case if the measurement in mg/l is preffered it is highly recommended to order a CCO-401 - conductivity / oxygen meter, in which the influence of the salinity on the oxygen concentration is automatically calculated, the value is taken from salinity measurement.
• ”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.
• Easy in use galvanic oxygen sensor.
• When properly handled and maintained, the sensor may be efficient for several years.
• 1 or 2 point oxygen sensor calibration.
• Automatic or manual temperature compensation.
• Wide measuring range enables measurements in lakes with blooming vegetation.
• Possibility of determining the purity of industrial oxygen.
•  

  Other features:

• Clock with date.
• Storing the date of next calibration and reminding it, in the right moment, to the user.
• Auto switch off function, with time set by the user, to protect the batteries against discharging.
• Internal data-logger for up to 4000 sets of results collected in series or singly with temperature time and date.
• The results and calibration data are stored in non-volatile memory.
• Possibility of connecting with a PC by a micro USB output and micro USB cable delivered in the set.
• 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 / micro USB cable.
• The meter meets the GLP requirements.
• 24 months of warranty for the meter.
• The standard set includes: COG-1 oxygen sensor, CT2B-121 temperature sensor with Pt-1000B resistor.

  Meets the GLP requirements.
