[EXPLORER] pH Sensor Safety

Post by EER_Mark » Wed May 08, 2019 11:25 am

Hello,

For teams using pH sensors with glass bulbs, how protected must those glass bulbs be? We'd like an official ruling / statement so we can properly meet all safety requirements.

Thanks!

I found a quote from the manual after, but it is still a little vague. "Companies using pH sensors with a glass body must protect the sensor from breakage. Companies may insert the glass-bodied sensor into a plastic tube to prevent breakage."

Our pH sensor's glass bulb is surrounded completely in circumference by a plastic tube, but it is exposed on the front and is not very deep within the tube.

An official ruling on glass bulbs would help us better prepare for the competition and meet MATE's requirements.

That is sufficient. If your glass pH sensor is surrounded by a plastic tube to prevent breakage, you are good. MATE does not want broken glass in the pool, but understand that the common pH sensor is made of glass. So provided that glass is protected against breakage, you are good.
