Overview
HF-5615 Industrial Dissolved Oxygen Meter (ppb)
Product Details
1、 Instrument Introduction:
The HF-5615 industrial dissolved oxygen analyzer is a ppb level dissolved oxygen analyzer that uses new polarographic analysis technology to ensure stability and accuracy in (ultra) low concentration measurements, greatly improving measurement performance and usage environment.
2、 Product features:
◆Single board structure, touch sensitive buttons, no switch knob or potentiometer.
◆DC+pulsed polarization voltage: greatly enhances stability in low concentration measurements.
◆Data processing method: It reduces the influence of membrane deformation, temperature, and flow rate changes on measurement values by hundreds of times.
◆Fast response, stable zero point, and small drift.
◆Prefabricated long-life permeable membrane, easy to replace.
◆Electromagnetic compatibility (EMC/RFI) design: Designed and manufactured according to European standard EN50081/50082.
◆Alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.
◆Network function: isolated current output and RS485 communication interface.
◆Historical curve: Continuously record data for one month, with one point every five minutes.
◆Notepad function: Record 200 pieces of information.
◆Manual current source: convenient for recording and testing devices.
◆Built in real-time clock: provides time reference for various functions, etc.
◆Password management: Both parameter settings and maintenance are password protected.
