WalkLAB Professional Conductivity meter HC9021

The WalkLAB Professional Conducivity-TDS-Salinity Meter HC9021 is a portable yet highly accurate Conductivity meter.? It is used in all industries as well as commercial and educational teaching aids.?? It has full functionality that matches an expensive bench meter.

The meter comes complete in a hard carrying case with calibration buffer solutions.

Advanced Features:

Large LCD with Multiple Display

Display of Condcutivity or TDS or Salinity with temperature and time simultaneously

Able to display reading in ?Siemen, mSiemen, ppm, ppt.

Autolock Measurement

Meter automatically sense a stabilized endpoint reading

This ensures workers only takes in an accurate reading

all the time and every time.

Multi-point calibration

Meter able to make up to 5 points calibration

Automatic Range

Meter able to automatically switch to the next higher range to enhance the accuracy over the 5 calibrated points.

Cell Constant

Meter can accept probe of different cell constant 0.1, 1.0 and 10.0

TDS Factor

TDS factor can be adjusted to allow higher accuracy of different type of chemical or liquid of known conversion.

Real Time Memory

Able to save records of up to 99 data memory with date and time, enable download to PC.

Online PC link

Able to link to a PC for online display with optional PC kit (sold separately) and download saved data.

Meter uses regular AAA size batteries and tap power source from PC when connected via the USB cable.
