The Datalogger Type 575-LTC is a compact instrument for measuring and recording water level, temperature and electrical conductivity. The conductivity can optionally also be used to derive the salinity. Additionally, to the well-proven reference pressure cell, a high-precision and insensitive conductivity sensor is used which, in addition to precise measured values, guarantees long-term stability. A recalibration of the conductivity sensor is, if at all, usually required only after many years of use.
Also provided with a large non-volatile memory for min. 253,000 records make the device ideal for pumping tests or tracer measurements. The integrated battery is designed for the unique lifetime of at least 10 years of operation with 3 million measurements before replacing it at the factory.
- Maintenance free - no desiccant / dry cartridges required
- Compact design with Ø 22mm for installation in pipes from 1-inch
- High-precise and long-term stable 4-pole conductivity sensor
- Conductivity sensor stable over years, no re-calibration necessary
- Check measurements by a Water Level Meter are possible without conversion or removal from 2-inch wells
- Power supply for 10 years operation and 3,000,000 measurements
- Made of high class stainless steel, for high corrosion protection
