Oxygen and Carbon Dioxide Measurement Made Simple
The 1737 oxygen and carbon dioxide analyser is the third generation of MAP gas analysers from Novatech Controls. It incorporates a novel zirconia oxygen sensor and an infrared CO2 measuring cell. It brings a new level of automated gas sampling for the food and pharmaceutical industry by including features such as:
- Bluetooth® data uploads
- 200 Product categories
- Power or battery operation
- Sample gas flow measurement and control
- Large graphic display
- Performs automatic zero calibration when reading ambient air
- Data memory for 3700 measurements
The 1737 analyser comes with a variety of gas measurement ranges that covers oxygen from ppm levels up 100%, and the option of CO2.
The sample gas flow rate is measured using a true mass flow sensor and allows the 1737 to maintain a constant flow rate and alarm if there is a blockage.
The Novatech 1737 Oxygen and Carbon Dioxide Analysers are especially suited to food and beverage applications including:
- Head space analysis in closed packages
- Head space analysis in cans
- Continuous process measurement
Accuracy and Reliability
The oxygen and carbon dioxide sensors provide accurate and virtually drift-free measurement for years. The oxygen sensor is automatically zeroed whenever the sample is from ambient air and only requires a calibration gas for the ppm level sensor.
The carbon dioxide is also zeroed whenever the sample is from ambient air and uses a simple keyboard operation for the span calibration.
The 1737 allows entry of up to 200 products by name and product number, entered from the instrument keypad or from a computer. Selecting a product automatically enables the preset alarm levels for the gas concentration and the measured results are stored in sets with a date/time stamp. The data can be transferred easily without errors or missed readings to a computer using the Novatech software in CSV (comma separated variable) format straight into the common spreadsheet applications. The software is provided free of charge.
The operator does not need to touch the analyser once the product has been selected. Every time the sample gas returns to ambient air the alarm levels are checked, the minimum/maximum measurements are stored and the display is updated.
The analyser can then be brought to within 10m of the computer, a button can be clicked on the PC and the data will be transferred by the radio link. It is not necessary to plug a communication cable into the analyser.
Tailor the analyser to the application
The Novatech 1737 analysers are available for oxygen only, or for both CO2 and oxygen with three oxygen ranges. The instruments can be selected with a pump where samples need to be aspirated, and with accessories (see reverse side) including:
- Metal can piercing tool
- Hypodermic needles for plastic packs
- Filters for dry particulate
