Portable, robust, dual-channel meter with high functionality and accuracy.
- Model SG78: pH, mV, relative mV, conductivity, TDS, salinity
- Twin-line, alphanumeric display of separate channel parameters and temperature
- Intelligent sensor management (ISM) stores information in a data chip on-board the probe, including calibrations (factory, current and up to last five historical), probe I.D. and measurement temperature for recall by the meter
- IP67 protected housing, with or without probes attached
- Data storage for 500 GLP date records with infra-red communication port
- 5-point pH calibration with a choice of 7 pre-defined and one user-defined buffer sets, manual or automatic temperature control
- High or low limit value display alarms with with audible signal selectable
- Separate PIN protection functions for key settings and data deletion
- Large, backlit LCD readout with user prompts and choice of 10 languages, probe condition indicator and user I.D.
Supplied as a field kit with IP67 probes with 1.8m cables, wrist strap, instructions, test certificate, declaration of conformity, batteries, case, rubber meter protection holster, probe clips, 2 x pH4.00 and pH7.00 and 2 x 1413µS/cm and 12.88mS/cm buffer sachets and calibration bottles.
