Bluelab Commercial Truncheon Meter - Manual (Page 2)

1.0 To operate
Using the Bluelab Commercial Truncheon ® Nutrient Meter (see Figure 1) to
measure nutrient conductivity involves placing the probe sensor head in the
solution, followed by measuring and reading conductivity values on the stem
scale indicator light.

Measure conductivity
Place probe into nutrient solution and take reading as
indicated by the fl ashing lights.
Note: If the lights are dancing between two values, the reading
is between those two values. Some example readings are
shown in the table below:
Note: For very cold or very hot temperatures it will take 1-2
minutes for the probe to reach solution temperature. To help
decrease time taken to reach the solution temperature, place
the probe in an area where there is a strong movement of
solution, or stir solution with the probe.
Obtain another reading
To take another reading, simply place back in solution.
Clean probe
We recommend the probe be cleaned once every two
weeks according to the Cleaning and Maintenance
instructions. This can vary depending on frequency of use.
