Measurement Parameters
LH-900: pH electrode, conductivity electrode, DO electrode and temperature probe
General Features
• Automatic temperature compensation ensures accurate readings over the entire range
• Auto-Read function senses and locks the measurement endpoint
• Calibration due alarm prompts user to calibrate the meter regularly
• Setup menu allows setting the number of calibration points,resolution,stability criteria, temperature unit, date and time, etc.
• Reset function automatically resumes all settings back to the factory defaults• Expanded memory stores or recalls up to 500 data sets
• USB communication interface for data transfer and timed interval readings
pH
• Multiparameter water quality meter is equipped with a 6.5 inches backlit LCD display• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers• Automatic electrode diagnosis shows the pH slope and offset
Conductivity/TDS/Salinity/Resistivity
• 1 to 5 points calibration with automatic recognition for conductivity standards• Selectable cell constant, reference temperature, TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes
• Automatic electrode diagnosis shows the calibration points and factors
Dissolved Oxygen
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution• Salinity and barometric pressure compensations eliminate the measurement error
