Portable Conductivity TDS Meter for Water Testing Lab

Portable Conductivity TDS Meter for Water Testing Lab

High-precision pH conductivity meter with 4 measurement functions. The instrument is suitable for laboratory measurement of pH, mV, conductivity and TDS values of samples.

Features

Conductivity/TDS mode features:

1)1 to 5 point calibration, automatically recognizes conductivity standard solution.

Optional electrode constant (K=0.1/1/10), reference temperature (20/25°C), TDS conversion factor, linearity and pure water compensation mode.

pH mode features:

1)High-precision pH conductivity meter with a backlit LCD display.

2)1 to 5 point calibration, automatically recognizes USA, NIST, DIN standard buffer solutions.

Automatic electrode diagnosis displays pH slope and zero offset.

General features:

1)Automatic temperature compensation ensures accurate measurement throughout the full range.

2)Automatic power off, effectively saving battery energy consumption.

3)Calibration expiration reminder prompts the user to calibrate the instrument regularly.

4)Automatic end point lock retains stable readings for easy review and recording.

5)Setup menu allows customization of calibration points, display resolution, stability conditions, temperature unit, date, and time, etc.

6)USB communication interface facilitates data transfer to a personal computer.

7)Expandable memory stores or retrieves up to 500 data sets.

8)Reset function automatically restores the instrument to factory default settings.

9)The multi-mode power supply scheme (battery, power adapter, computer USB port) ensures smooth application of the instrument.
