  • Q:

    Do I need a special probe to measure in the 50 to 200uS range?
    Asked on 10/27/2010 by T from Teck

    1 answer



      This meter comes with a probe that has a cell constant of k=1. The low end of this probes range is approx 1us. and can read up to 200ms.

      Probe 19600-60 has constant of k=0.1. The average range is less than 0.1us up to 300us.

      Either probe will work for your range though the 0.1 constant is more in the middle of it's range for what you are working with.

  • Q:

    What is the minimum volume for reading? I have very low volumes, i.e. 1,000 uL. Can this meter be used for that?

      This unit would require enough fluid to cover the holes of the probe, then fill it. I estimate one would need at least a 50 mL sample for this.
      The smallest volume required by a conductivity/salinity tester comes from the cup style meters currently, please see part number 35662-15, and it requires about 1.5 mL.

  • Q:

    Does Cole parmer offer a A2LA or equilivent calibration certificate other than the NIST calibration service. What is the cost.
    Asked on 3/9/2010 by Pete from Bloomington, IL

    1 answer



      Our NIST calibration service is A2LA and ISO 17025 certified.

  • Q:

    Will I need an additional probe to measure 2000mS/cm or will this kit come with everything needed to measure to 2000mS/cm.
    Asked on 2/10/2010 by Anonymous

    1 answer



      The probe that comes with this kit will have a maximum range of 200mS. You will need the probe part number 196200-62, cell constant of 10, to reach the upper ranges of this meter/1999mS.
