Multiparameter Water Quality Meter Features:

The probes are made of high-quality titanium alloy for accurate measurement, which is more sensitive and lasts longer.
1 to 5-point calibration, automatic recognition of USA, NIST, DIN standard buffers.
Reliable Automatic Temperature Compensation (ATC) ensures accurate measurements in water sources of all temperatures.
The water quality meter turns off automatically after a few minutes of inactivity to save batteries.
Automatically saves the measurement results after completion, making it easy to view the data later.
Ideal for aquariums, hydroponics, marine, aquaculture and any water source.
Concentration units (ppm, mg/L, mol/L, mmol/L) and ionic media are selectable
Salinity and atmospheric pressure compensation eliminates measurement errors.
USB interface for easy data transfer
Can save 500 sets of measurement data for easy comparison
