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.
²High temperature versions available on request.
*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).
