Please note: Battery /Liquid/Powder cannot be included during the shipping

Multiparameter water quality meter contains 8 measurement modes, the meter is suitable for measuring the pH,temp , conductivity, TDS, salinity, resistivity and DO.

Features:

1. 5-inch LCD screen, 150 degree viewing angle, beautiful design, light weight.

2. Compact support and rotating electrode holder, and can be fixed on the wall, saving space.

3. Small size, easy to carry, can be moved freely in the laboratory

4. Scalability: You can easily and quickly change different electrodes to measure pH, conductivity or dissolved oxygen.

5. Automatically recognize the electrode type. The electrode with the built-in chip can automatically store calibration data, and automatically retrieve the calibration data after connecting to the machine.

6. The 3.5mm electrode connection cable is simple to connect and easy to use.

7. 2 USB excuses, charging, copying data, connecting to a computer for easy data transmission.

8. 200 data logs can be stored, data settings include readings, GLP data, date and time.

9. Two operating modes: extended and basic operating modes; for example: in extended operating mode, there are 5 points of calibration and 2 customized buffers can be used; in basic mode, only 5 pre-programmed buffers and 3 points calibration.

10. The battery can be used continuously for 30 hours. Available for 2 weeks. Automatic shutdown in 10 minutes, the longest can be set to 30 minutes
