¹All high pressure sensors are potentially dangerous and care must be taken not to over-range them beyond their calibrated range. Sensors are tested to 150% of the range to provide a factor of safety.

²Custom, high temperature versions available on request.
For standard high temperature piezometers, please see the Model 4500HT Series.

*Please Note: All GEOKON vibrating wire piezometers include tripolar plasma surge arrestors to protect the sensor coils from possible lightning damage. Semiconductor piezometers are also available (see 3400 Series).

Please Note: GEOKON maintains an ongoing policy of design review and reserves the right to amend products and specifications without notice. Various instruments are discontinued over time and replaced with new, updated models.
