Description
pH
• Multi parameter water quality meter is equipped with a 3.5 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
ORP
• 1 point offset calibration allows adjusting the displayed value to a known standard
• Relative and absolute millivolt modes ensure the reliable ORP measurements
Ion Concentration
• 2 to 5 points calibration, including the 8 concentration points can be selected
• Direct ion concentration readout simplifies the measurement process
• Automatic electrode diagnosis shows the calibration points and slopes
• Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency
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
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
• Auto-Power Off effectively conserves battery life
• 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 is easy to transfer data to PC
• Multi-mode power scheme (batteries, power adapter and USB port) ensures that using
