TR-ON series waterproof pocket conductivity tester nclude the ELECON20, 30 and 40. The meters are used to measure electrical conductivity value of liquids without temperature compensation function. 

Single Point Push-Button Calibration:
TR-ON series with one point calibration function. The meter is permitted to use user-defined calibration solution, you need only set conductivity value in meter and immerse the electrode into standard solution, then press CAL key, the meter will be calibrated automatically.

Hold Function:
The meter with hold function, press HOLD key, you can
freeze reading temporarily for easy viewing.

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

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

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

Applications:
TR-ON20 is used to measure low conductivity liquids.
E.g. Pure water, Distilled water etc.
TR-ON30 is used to measure general conductivity liquids. E.g. Tap water, Table-water etc.
TR-ON40 is used to measure high conductivity liquids.
E.g. Waste water, Salt water etc. 

What's included:

Meter, Alkaline button cell batteries.
