testo 206 pH1, pH2 and pH3
• The instrument is also suitable for outdoor
applications or for tough industrial
conditions thanks to the “TopSafe”
protection case included.
• 2 line display
• Automatic full scale value recognition
• 1, 2 or 3 point calibration possible
testo 206 pH1 and pH2
• Insensitive to dirt on account of hole
diaphragm and gel reference electrolyte
• Large volume of the gel reference electrode
guarantees a long life
• No maintenance necessary. No need to fill
up electrolyte solution.
• So versatile it can be used for nearly all
applications:
- for materials containing protein
- highly contaminated solutions can be
measured
• Low membrane resistance results in fast
and stable readings
• Unique design makes breakage practically
impossible
• Combination: pH penetration tip with
temperature measurement probe
testo 206 pH3
• Connection of all external probes with BNC
plug
• Automatic and manual temperature
compensation possible
pH1 probe head for liquids pH2 probe head for semisolid materials pH3 probe head with BNC interface
