Special Features:

Crosslinked polymer is resistant to heat, solvents and to most chemicals. Sensor holds an excess of KCl, assuring saturation at all temperatures and extending in situ sensor life. The major advantage of the MUGG Fluoride and CH III Acid Resistant pH Glass is the lack of building fluoride precipitates on its surface while in use, therefore it does not require cleaning and frequent calibration. The composition of the glass also reduces the attack of fluorides more than ten fold relative to general glass compositions. It further resists high concentrations of acids and with its reference electrode system permits pH measurements well into the negative range.

Recommended Applications:

Fluoride containing wastewater, etching solutions, pollution control devices, where long service life or operation at remote locations where (no) low maintenance is required.

 Storage and Shelf Life: At room temperature with closed protector cap, 1 year from date of manufacture.
