Coffee TDS/Temp. Meter

Dont over/under-extract your coffee. Measure your TDS!!

This 3-in-1 combo TDS meter measure - temperature, conductivity and total dissolved solids at verious calibration scales. It is ideal for measuring brewed coffee TDS and for determining both the strength and extraction for specific lots of coffee.

Once recorded, TDS measurements can be plotted against the SCAA Brewing Control Chart to determine optimal extraction levels and ultimately brewing quality.

Features:

* Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.   
* Three different calibration options (KCl, 442TM, NaCl)

* Automatic Temperature Compensation (ATC) using three temperature coefficients.
* Waterproof housing.
* Measurement Range: 0-9990 µS; 0-8560 ppm (auto-ranging).


* Digital Calibration (push button)


* Auto-off function, data-hold function and low-battery indicator.


* Display: large and easy-to-read LCD screen includes simultaneous temperature reading.


* Factory Calibrated: The COM-100 meter is calibrated with a 1413 µS solution. 


* Includes a cap, batteries and lanyard.

Specifications:

* EC Range: 0 - 9990 µS
