Quick start guide 

Before you use your Leap Probe: 

  1. Attach the Leap Probe to the meter via the BNC fitting (metal end). 
  2. Remove the storage cap. Hold the cap and twist the base one full turn, then gently remove. Salt crusting on the probe is normal.
  3. Precondition the probe before first use by inserting probe several times in media and then clean. Do not scrub glassware, only rinse.
  4. Calibrate your probe to your Bluelab meter, monitor or controller by following the instructions on the back of the probe, read the calibration guide here.

Quick tips for care

Don't let your probe tip dry out. Store the Leap Probe in the storage cap, ensuring there is enough KCl (Potassium Chloride) storage solution in the cap. Read more on KCl storage solution.

Measuring highly abrasive media like soil and potting mix 50 or more times per week? If you are using your probe regularly, weekly calibration is recommended. 

Never store or soak the probe in RO water (Reverse Osmosis) water. RO water changes the chemistry in the reference, causing the probe to break. 

Never immerse the probe in oils. Avoid touching the probe tip directly to avoid leaving a film on the glass bulb.  

Avoid knocks and and sideways force. This could damage the delicate glass.
