Level TROLL 700H Instrument
Comply with the Office of Surface Water by using the most accurate pressure
transducer available. The Level TROLL 700H meets the surface-water specification of
±0.01 foot.
For accuracy under all operating conditions, instruments are calibrated over the full
pressure and temperature range. Each instrument includes a serialized, NIST-traceable
calibration report.
