Multiparameter Meters
Bante904 Benchtop Conductivity/Dissolved Oxygen Meter
Multiparameter conductivity/dissolved oxygen meter offers 5 measurement modes for accurate measurements of conductivity, total dissolved solids, salinity, resistivity and dissolved oxygen, suitable for laboratory use.
Features:
Conductivity/TDS/Salinity/Resistivity
? 1 to 5 points calibration with automatic recognition for conductivity standards.
? Automatic electrode diagnosis shows the calibration points and factor.
? Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear and
pure water compensations, seawater and practical salinity measurement modes.
Dissolved Oxygen
? 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
? Salinity and barometric pressure compensations eliminate measurement errors. 
Other Features
? Automatic temperature compensation ensures accurate readings over the entire range.
? Auto-read function senses and locks the measurement endpoint.
? Calibration due alarm reminds user to calibrate the meter regularly.
? Setup menu allows setting the number of calibration points, stability criteria, temperature unit,
date and time, auto-power off, etc.
? Reset function automatically restores all settings to the factory defaults.
? Expanded memory stores or recalls up to 500 data sets.
? USB communication interface enables easy data transfer to a PC.
? DAS software is capable of receiving data, recording measurements at specified intervals,
exporting data to Excel.
