Description
Professional Conductivity-TDS-Salinity Meter TR-DO90 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.
Large LCD with Multiple Display
Display of Conductivity or TDS or Salinity with temperature and time simultaneously
Able to display reading in µSiemen, mSiemen, ppm, ppt.
Auto-lock 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.
