Der CSIM11 misst den gesamten pH-Bereich von Flüssigkeiten. Er kann im Wasser versenkt werden oder in Tanks, Rohrleitungen und offenen Kanälen eingesetzt werden. Der CSIM11 ist nicht für Anwendungen unter Druck ausgelegt, mehr als 30 psig sind nicht möglich.
Wenn Sie einen Sensor für Anwendungen in Rohren unter Druck brauchen, kontaktieren Sie Campbell Scientific.
Lesen Sie mehrThe CSIM11 has a plunger-style pH glass electrode that allows the CSIM11 to be mounted at any angle. Its porous polytetrafluoroethylene (PTFE) liquid junction is less susceptible to clogging as compared to conventional reference junctions.
A titanium ground rod runs inside the PPS outer body to eliminate ground loop errors. An internal amplifier boosts the signal, decreasing signal interference. The amplifier is powered by two internal lithium batteries, and thus does not require any power from the datalogger. These batteries are designed to last the lifetime of the probe.
The reference solutions and bulb configuration are optimized for natural water applications. Alternate reference solutions and bulb configurations are available. Contact Campbell Scientific for pricing and availability.
Note: The CSIM11 uses glass bulb technology which has a life expectancy of around 6 months to 2 years, depending on the conditions of the water.
