Oxygen Sensor Overcoat
MGB is black in color and powerfully blocks ambient light and interference from sample color. It also helps protect against light physical abrasion [Note: You need to purchase a puncture accessory for any readings that require placement in stoppers or pushing through films such as thick agar gels.] and polar solvents. However, the MGB overcoat will not maintain a factory calibration for solvents, but your chemistry will not be compromised and you can perform two point calibrations on site. This overcoat will reduce resolution and is not recommended for 300 micron probes or use in oils.
In addition, MGB overcoat is recommended for:
- colored samples
- soil measurements
- environments with auto-fluorescence
- environments with high ambient light
- polar organic solvents
