Product Description

DWG-5088 Industrial online Sodium Meter
 DWG-5088 Industrial Sodium Meter is a brand new continuous monitoring instrument for micro-sodium ions atppb level. With professional ppb level measuring electrode, automatic constant-voltage constant-current fluid linesystem and stable and efficient basification system, it provides stable and accurate measurement. It can be used forcontinuous monitoring over sodium ions in water and solution in thermal power stations, chemical industry,chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical engineering, foodstuff, runningwater supply and many other industries.FeaturesLCD display in English, menu in English and notepad in English.Computer-based: Multi-parameter measurement, temperature compensation and automatic range conversion areachieved thanks to the high-performance CPU chip, high-precision AD conversion technology and SMT pastingtechnology, resulting in high precision and repeatability.High reliability: Single-board structure, touch keys, no switch knob or potentiometer. Rapid response, accuratemeasurement and high stability.Automatic constant-voltage constant-current liquid line system: Automatic compensation for flow and pressure ofwater sample.Alarm: Isolated alarm signal output, discretionary setting of upper and lower thresholds for alarming, and laggedcancellation of alarming.Network function: Isolated current output and RS485 Communication Interface.History curve: It can continuously record data for a month, with a point for each five minutes.Notepad function: Recording 200 messages.Technical Indexes1.Measuring range : 0 ~ 100ug / L, 0 ~ 23000mg /LResolution : 0.1 μg / L, 0.01mg/L0.00pNa-8.00pNaResolution : 0.01pNa0 ~ 60 ºC Resolution : 0.1 ºC2.The basic error : ± 2.5%, ± 0.3 ºC temperature3.Automatic temperature compensation range : 0 ~ 60 ºC, 25 ºC basis4.The electronic unit temperature compensation error : ± 2.5%5.The electronic unit repeatability error : ± 2.5% of reading6.
