GrainPro Oxygen Meters

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.

 

Oxygen Meter - 1-yr. Sensor (GPO2-HH)

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.

Oxygen Meter - 5-yr. Sensor (GPO2-AN)

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.
