In addition to its conventional Oxygen Meter - 1-yr. Sensor (GPO2-HH), GrainPro launches a new type of analyzer that has a sensor with a five year life span and an improved digital display Oxygen Meter - 5-yr. Sensor (GPO2-AN). This new analyzer also has an auto shutdown feature. Each analyzer is priced differently and is currently available to order.
This basic O2 analyzer is essential equipment for Modified and Controlled Atmospheres. For Ultra Hermetic™ storage, it enables O2 level monitoring and the condition of the commodity stored. In the case of controlled atmospheres, it can measure CO2 concentrations by using an O2 - CO2 conversion table.
The design of the analyzer is kept as simple as possible to reduce chances of breakdowns and reduces production cost and the unit's price. A model with an electric pump is available by request. This Common O2 in the air and converts this chemical reaction into a digital signal. The chemical sensor has a limited life span, usually in the range of 1 to 1.5 years even when not used.

The new GrainPro Oxygen Meter - 5-yr. Sensor (GPO2-AN) is capable of measuring oxygen levels between the 0 to 21% range. This new analyzer has a long life oxygen sensor which is expected to last for more than five years. It comes with an auto-off function that activates after 8 minutes of inactivity.
High concentrations of carbon dioxide do not affect the sensor's life span and accuracy, making it perfectly suitable for monitoring gases inside regular and G-HF Cocoons. The analyzer can be used at high elevations without the need for any correction.
