คุณสมบัติ HI9147
- Replaceable Membrane Caps: The pretensioner high-density polyethylene (HDPE) membranes employ a screw cap design that can be changed quickly by simply filling with the HI7042 electrolyte fill solution and screwing onto the DO probe.
- Galvanic Measuring System: The meter and probe use galvanic sensor technology where the electrodes’ potential difference drives the reaction, requiring no external voltage. The probe is comprised of a silver cathode and zinc anode in an electrolyte solution held in place over the surface of the electrodes by a polymer membrane. Oxygen diffuses across the membrane and the system establishes a current proportional to the concentration of dissolved oxygen present.
- Automatic Temperature Compensation: All readings are automatically compensated for temperature variations with a high accuracy, built-in linearized thermistor temperature sensor behind a stainless steel cover.
Altitude Compensation: The HI9147 allows for altitude compensation for up to 4000 meters with a 100-meter resolution. - Salinity Compensation: Salinity compensation is adjustable from 0 to 51 g/L (ppt) with a 1 g/L resolution for the measurement of DO in brackish and sea water.
- Backlit LCD: The HI9147 has a display with a backlight for easy viewing of readings in poor lighting conditions
