Conductivity Plμs Tape
Unlike other similar units on the market, the Conductivity Plμs uses a measuring tape with a high tensile steel core, tested for stretch resistance to ASME standards. Two seven strand stainless steel conductors add to the strength of the tape. The measuring scale is printed on the inner core which is then jacketed in medium density polyethylene ensuring lasting legibility and a long tape life. The tape graduations are in decimal feet with markings at each 1/100th foot or metric with markings at each mm.

Conductivity Plμs Electronic Module
The Conductivity Plμs electronic module houses an LCD screen which displays conductivity values up to 80,000 micro siemens, and a temperature range from -20˚C to +85˚C. A super bright red LED and an 80dB buzzer are also housed in the module. The electronics are based on A/C current. This helps prevent probe corrosion and fouling. The Electronics are protected from dust and moisture by an epoxy based conformal coating. The unit is powered by a single 9v battery also mounted on the module.

Conductivity Plμs Probe
The Conductivity Plμs probe utilizes a four electrode system comprising of two arrays of a single electrode within a concentric electrode. Each array reverses its polarity 1000 times per second. This system drastically reduces electrode corrosion ensuring reproducible readings. Water level is sensed when the probe passes from a non conductive medium (air) to a conductive medium (water @ more than 10 m.s.) The Probe is 0.75in diameter x 8.0in long (19mm x 203mm).

Conductivity Plμs Reel
The Conductivity Plμs is a well balanced unit. The stand alone, sturdy steel frame is coated in Polyurethane for durability. The Vinyl coated carry handle is ergonomically designed for comfort and easier rewinding. The reel flanges and center hub are molded from high strength Nylon running on a stainless steel axle allowing the smooth running of tape up and down the well or borehole. The third hand well casing hanger and tape guide are standard features on all Heron meters. (Excluding little dipper).

Conductivity Measurements:
The Conductivity Plμs meter is standardized against standard conductivity solutions at 25˚C. The meter measures the temperature and automatically converts readings to specific conductivity values. The conductance temperature coefficient is 2.0% Calibration is easy, using readily available 1413us solution. The auto off facility activates after five minutes of zero conductivity profiling.

Temperature Measurement
The Conductivity Plμs will withstand and measure temperatures to +85˚C. The temperature range is -20˚C to +85˚C. The temperature is displayed on the LCD screen on the electronic module. A response time of approximately 10 seconds allows for temperature stabilization. The auto off facility activates after five minutes of zero temperature profiling.
