เครื่องวัดออกซิเจน DO Meter รุ่น HANNA HI9147

 

 

 HI9147  Dissolved Oxygen / °C - Meter, Galvanic DO Probe

  • 123Designed specifically for aquaculture
  • Galvanic DO probe
  • Backlit LCD
  • Automatic Temperature Compensation
  • Manual salinity and altitude compensation

HI 9147 is designed for aquaculture applications. This unit is unique among our family of DO meters as it is supplied with a galvanic probe.  Unlike polarographic probes, galvanic DO probes require no conditioning time. When you need to measure multiple samples in a given period of time, pick it up and measure on demand.

HI 9147 is a must have for DO sensitive organisms or high bio-load environments.
