Main featureMicrocomputer: Using high-performance CPU chip, high-precision AD conversion technology and SMT technology, complete multi-parameter measurement, temperature compensation, automatic range conversion, instrument self-test, high accuracy and good repeatability.High reliability: single board structure, touch buttons, no switch knobs and potentiometers.Fast response, accurate and stable measurement.Waterproof and dustproof design: Protection class IP65, suitable for outdoor use.Electromagnetic Compatibility (EMC/RFI) Design: Designed and manufactured according to the European standard EN50081/50082.Alarm function: alarm signal isolated output, alarm upper and lower limit can be arbitrarily set, the alarm lagswithdrawn.Network function: Isolated current output and RS485 communication interface.Historical curve: continuously record data for one month, one point for five minutes.Notepad function: records 200 messages.Manual currentsupply: facilitates recording and testing devices.Built-in real-time clock: Provides time reference for various functions.Industrial Control Watchdog: Make sure the meter does not crash.Can be measured off-line:replacelaboratory sodium meter,use for testStandard fluidcheck the performance of the instrument.low cost, low maintenance.
Note
1. the length of the electrode cable, default is10m.
2. If electrode cable length exceeds 20m, should be equipped with pHRT-1 impedance converter.
3. Please confirm installation method of electrode and secondary instrument.
4.For power supply, not specified according to AC220V distribution.
