Fiber Optic Meter for pH Microsensors

pH-1 micro

The pH-1 micro is a precise fiber optic pH meter. It is temperature compensated and used with pH microsensors based on a 140 μm optical fiber. A PC is connected to run the user-friendly software. pH-1 micro is additionally equipped with an analogue output and a trigger input.

  • For use with pH microsensors
  • Simple one-point calibration possible
  • Software included

Applications

pH Measurement in Plants & Animals

pH Microsensors can be implemented in plant tissue or even in small animals. New insights in physiological aspects can be obtained. Due to the small size of the probes only a minimal disturbance will occur.


pH Measurement in Small Volumes

Due to the small dimension of the probe, pH measurements can be done in very small volumes - even in microtiter plates of a higher format like 384 or 1536. No need for reference electrodes - a real step forward, especially in small volumes. Of course, the measurement is independent of electromagnetical fields - this even allows measuring in NMR spectrometers.
