Fixed Hydrogen Gas Detector H2 Gas Leak Alarm Monitor Detector with 0-2000PPM

Fixed Hydrogen Gas Detector H2 Gas Leak Alarm Monitor Detector with 0-2000PPM Advantages:Employing overseas original sensor.Standard equipped with three-wire system 4-20mA analog output; relay output; RS485 output (optional)Unique infrared ray control function, which can non-contacted controlthe device. Being compatible with all kinds of controlled alarms, PLC, DCS and other control system, can be remote monitored.Explosion-proof design, fast, reliable and stable. Explosion-proof grade: II 2G Ex db IIC T6 Gb IP65With self-calibration function and three standard keys will be used to realize on-site maintenance. Features:Monitor the H2 Hydrogen gas concentration in environment or pipeline and alarm. With self-calibration and zero calibration function, makes the detection more accurate and reliable.With temperature compensation, this is able to realize gas concentration compensation under conditions of different temperatures. Two-stage alarm with sound and light, alarm point is settable.Infrared ray controller can remote control alarm point settings, zero calibration, and address modification. Can output one or two on-off signals, can drive ventilator or solenoid valve and other external devices.

LS310 Digital Multi-Parameter Water Quality Tester is a of drinking

LS310 Digital Multi-Parameter Water Quality Tester is a special instrument for testing the water quality of drinking waterSolve the problem of drinking water quality testingNo reagent, measure 6 water quality indicatorsIntelligent scoring to determine the different levels of water qualityPen type design, easy to carryWith ambient temperature compensation, stable valueLS310 water quality tester is a special instrument for testing the water quality of drinking water, using UV absorbance method to measure the COD, TOC and UV275 water quality parameters of drinking water, by measuring the conductivity between the electrodes to obtain the TDS and conductivity of drinking water. The instrument can measure 6 water quality indicators at the same time, and judge the water quality all-round. LS310 water quality tester is mainly used for testing tap water, purified water and groundwater and other drinking water. Feature Intelligent scoring, indicating 4 different levelsThe instrument through the LCD backlight color indicates fine quality, good quality, average quality and poor quality 4 levels, the measurement results are very intuitive. No reagents, measuring 6 water quality parameters simultaneouslyThe instrument does not need any reagent, can measure COD (chemical oxygen demand), TOC (total organic carbon), UV275 (ultraviolet absorption value), TDS (total dissolved solids), electrical conductivity, temperature 6 water quality indicators at the same time, all-round evaluation of water quality. Solve the traditional water quality testing pain points● Traditional water quality testing pain points● Time consuming laboratory tests by testing institutions● Large-scale testing equipment and consumables are expensive● TDS water quality testing index single, can not be true and comprehensive judgment of water quality● Sudden water quality pollution, the user hindsightMulti-dimensional parameter scoringMineral water is rich in trace elements, avoiding the problem of inaccurate data judged by TDS alone.Indirectly reflect the residual chlorine content in waterIndirectly indicate the residual chlorine content of water through UV275 indicator, the higher the residual chlorine content, the larger the UV275 valuePen design, compact and portableThe instrument is designed in pen style, compact and portable, easy to carry and use.ParametersMeasurement ObjectTap water, purified water, bottled water, ground water, surface water (non-sewage) and other drinking waterMeasurement parametersCOD (Chemical Oxygen Demand)TOC (Total Organic Carbon)UV275 (Ultraviolet Absorption Value)TDS (Total Dissolved Solids)Electrical conductivityTemperatureMeasurement RangeCOD(0-100mg/L),TOC(0-100mg/L),UV275(0-1.0au/cm),TDS(0-2000ppm),Electrical conductivity(0-4000us/cm),Temperature(0-50℃)ResolutionCOD(0.01mg/L), TOC(0.01mg/L), UV275(0.001au/cm), TDS(1ppm), Conductivity(1us/cm), Temperature(0.1℃)AccuracyCOD: 0-5mg/L:±0.5mg/L; 5-100mg/L:±10%H，H is the standard valueTOC: 0-5mg/L: ±0.5mg/L; 5-100mg/L: ±10%H, H is the standard valueUV275: 0-0.1au/cm: ±0.01au/cm; 0.1-1.0au/cm: ±10%H, H is the standard valueTDS: ±3%FS, FS is the full scale valueElectrical conductivity: ±3%FS, FS is full scale valueTemperature: ±1℃Display240*135 1.14 inch TFT color screenPower Supply2 AAA alkaline dry batteriesSize157 * 37 * 14mmWeightAbout68gWorking Temperature Range0~50℃Storage Temperature Range-10~60℃，0~85%RH（no condensation） PackingNo.Product NameQuantityUnit1Water Quality Tester1set2AAA alkaline battery2pcs3Special Lens Cloth1pcs4User Manual1pcs5Certificate / Warranty card1pcs INTERNATIONAL SHIPPING:The package will be shipped by DHL, FEDEX or EMS.
