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.
