The SENTRON Red-Line probes series are for general purpose applications up to 60°C. Within the Red-Line series, there are five different probe-tip types:

-     Standard for general purpose use and for very small sample volumes,

-     ConeFET for application in highly viscous materials: jellies, pastes, slurries.

-     SurFET for application in direct surface measurements

-     LanceFET for application in semi-solids: fruit, meat, fish, soil etc.

-     LanceFET with handle for LanceFET applications where your hands might get slippery and you might loose your grip on the barrel when applying force to insert the probe in the sample or cold environments where gloves are worn.

To avoid disapointment, please make sure you have selected the right member of the comprehensive SENTRON probe family. This can be seen from the type-name on the barrel of the probe.

GENERAL

REFERENCE GEL may be observed as a viscous material on the tip of the probe. Some gel seepage from a new probe is normal and will not affect longevity or performance. Clean as above.

SAMPLES MUST BE aqueous liquids or semi-solids. Rinse with deionized or distilled water between samples.

TO ENSURE MIXING, stir samples or buffers for 5 seconds with the probe or a mag netic

stirrer, stop stirring and record results when stable.

PROTEINS, FATS AND OILS may be removed by scrubbing in a solution of Terg-A-Zyme (Alconox Company), Neutrad ^® or Neutracon (Decon Laboratories), pepsin solution or similar product. Rinse thoroughly with deionized or distilled water.

SPARE PROBES should be rotated with those in active use every 30 - 60 days to minimize reference junction dehydration and reduce initial start-up time.

BUFFERS. pH 7.00 (phosphate) and pH 4.00 (biphthalate) buffers are less susceptible to CO ₂ contamination than pH 10.00 buffer (borax or carbonate). When slope error occurs, it usually indicates a failing probe or contaminated buffer. If seen when using pH 10.00 buffer, try calibrating with pH 7.00 and pH 4.00 buffer. If a good slope is achieved, try a new bottle or different Iot of pH 10.00 buffer.

WHEN TESTING IN DIRECT SUNLIGHT or on a bright, reflective surface, use brown, opaque or shielded sample containers.

Chemical resistance:              Refer to your SENTRON meter manual. If doubts concerning applicability arise, please contact your local dealer.

                                               If you have purchased a new probe to fit your old type pH-meter (701, 1001, 2001, 3001), contact your dealer to receive an updated information an the chemical-resistance of the probe.
