What are the advantages of using an ISFET chip pH sensor instead of a glass bulb pH sensor?

The ISFET chip is housed in a non-glass body that is more durable than glass. Because an YMJDEA ISFET chip pH sensor is more rugged, it can be deployed in the field for longer durations without requiring maintenance.

Because an ISFET chip pH sensor does not use fragile glass in its construction, this type of sensor provides an alternative in applications where the potential for broken glass could be problematic to personnel, organisms, or processes.

Because an ISFET chip pH sensor does not have a measuring electrode with a glass membrane, the pH sensor can be stored dry  Also, the need to refill the buffered solution in the measuring electrode is eliminated.

ISFET chips have increased sensor stability at low temperatures, so the calibration frequency is reduced.

The response rate of ISFET chip pH sensors can be ten times faster than glass bulb pH sensors, thus providing faster measurements and enabling better process control.

An ISFET chip pH sensor is smaller than a glass bulb pH sensor because an ISFET chip can be made smaller than a glass membrane.

ISFET chip pH sensors are less susceptible to aging than glass bulb pH sensors.

Because the ISFET chip pH sensor does not have a pH sensitive glass membrane, it is more resistant to attack from highly acidic or highly alkaline sample solutions. ISFET chip pH sensors reduce the acid and alkaline errors common in extreme pH applications without the need for special glass.
