Oxygen Electro Optical Modul: DOPO2-FIBER OPTICS

     DOPO2-FIBER OPTICS is an electro-optical module that is designed for coupling to optical fiber sensors for remote monitoring of dissolved oxygen and gas. It can be used with a variety of fiber optics with different sizes from large field applications to very small (needle-size) biological environments. It also has Bluetooth capabilities and a built-in USB rechargeable battery.  Communication module embedded into it supports

·       4-20mA analog output

·       RS485

·       USB

·       External temperature sensor interface

                           ·       Bluetooth for android devices   


     DOPO2-FIBER OPTICS system should be attached to fiber-optic oxygen probes of different sizes with an embedded temperature sensor, allowing remote monitoring of dissolved oxygen in small spaces.  

      DOPO2-FIBER OPTICS system is equipped with a rechargeable internal battery that can be charged from a USB port and it runs for 8 hours when it is fully charged.

      The user can connect it to a PC via USB and saves data in a Microsoft Excel format or use it with an android device through Bluetooth and saves data in CSV format. 

   Similar to DOpO2-PRO, it can be configured with single-channel LED excitation and detection, and modulation frequencies up to 31.2 kHz.

       Fiber Optic probe is not included in the price.
