TR-ONM series waterproof pocket conductivity/oC tester include the ELEEC20, 30 and 40. The meters are used to measure electrical conductivity and temperature value of liquids with temperature compensation function (25oC).

Single Point Push-Button Calibration:
TR-ONM series with single point calibration function. The meter is permitted to use standard conductivity solution, you need only set conductivity value of the calibration

solution at 25oC and immerse conductivity electrode into conductivity solution, then press CAL key, the meter will be calibrated automatically. 

Hold Function:
When measure the sample solution, you need freeze reading temporarily for ease of recording. Waiting for a stable reading, press HOLD key, then the meter will hold the value. 

Replaceable Electrode:
ELEEC series with platinum sensor, giving you quick, reliable conductivity measurement. Double junction sensor, you can replace it easily. 

Automatic Temperature Compensation:
TR-ONMseries with temperature sensor, you can view temperature through oC key. The meter with automatic temperature compensation for accurate reading under changing conditions.

Auto-Power Off:
The meter will turn itself off approximately 8 minutes after last key pressed, it saves battery power after non-use.

Applications:

TR-ONM20 is used to measure low conductivity liquids.

E.g. Pure water, Distilled water etc.
TR-ONM30 is used to measure general conductivity liquids. E.g. Tap water, Table-water etc.
TR-ONM40 is used to measure high conductivity liquids.
E.g. Waste water, Salt water etc. 

Waterproof Function:
The meter with good waterproof performance, It can float on water.
