Describe the sizes of the various non glass, stainless steel ISFET pH probes?
IQ Systems general-purpose non-glass stainless steel ISFET probes are approximately the same diameter as glass probes(12mm); ISFET micro probes have a much smaller barrel (3.8-4.8mm) suitable for test tubes, NMR tubes, etc. The general-purpose probes are approximately 15cm in length; the micro probes are approximately 20cm in length (stainless steel portion). Micro probes constructed for NMR tube applications are approximately 25cm (10 inches) in length. Custom probes of varying lengths or probes with varying cord lengths can be ordered at an additional cost.
