Ohaus STCON3 Conductivity Probe

The OHAUS Starter Series are designed to produce exact results time and time again.  They fit perfectly in holders on OHAUS bench meters as well as clips on all OHAUS portable meters. 

The STCON3 utilizes the 4-ring potentiometric method for measuring conductivity, which incorporates a series of four stainless steel rings formed into the probe shaft. This design eliminates polarization which occurs with the 2-plates amperometric method.  Furthermore, without polarization the probe can measure a wider range of conductivity values because it does not suffer from electrolysis.

Specifications:

  • Connection: Mini-Din
  • Cable Length: 1m
  • Shaft Length: 130 mm
  • Shaft Diameter: 14 mm
  • Temperature Range: 0-50 ˚C
  • Measurement Range: 70 µS/cm - 200mS/cm (0.5% accuracy) ; 2 μS/cm - 70μS/cm (1% to 5% accuracy)
  • Compatible With: ST300C portable meter

CARE AND USE

The STCON3 conductivity probe has a built-in temperature sensor which is 30kΩ.  When using STCON3, please consider the following:

  1. Make sure the plastic shield is in place when measuring.
  2. Be sure the solution reached the line on the plastic shield and below the vent hole when measuring.
  3. To prevent carry over from high to low conductivity solutions, rinse with distilled water between and after measurements.
  4. Make sure the cell chamber is bubble-free.
  5. Allow sufficient time for the sensor to stabilize when measuring samples at different temperatures. A manual end-point is advised.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.
