WATER QUALITY METER

Alat Ukur KekeruhanTURBIDITY METER HI 93703 series are microprocessor based turbidity meters that provide laboratory accuracy for field turbidity measurements.The HI 93703 is easy to calibrate (with 3 point calibration) using AMCO-EPA standards and is ISO 7027 compliant.HANNA instruments has chosen 10 FTU* as the calibration point because it is the value that best fits the water turbidity measurements in different applications, from drinking water to wastewater treatment. HANNA instruments uses the primary standard AMCO-AEPA-1 to avoid all formazine-related problems. Formazine is a very toxic, unstable substance which requires particular care: its standards have to be prepared only a few minutes before performing the calibration, and cannot be reused because of their short life. HANNA AMCO-AEPA-1 standards are extremely stable, can be reused, and last up to six months if free from contamination. HI 93703 can be used with both standards.The HI 93703-11 enhanced version features a real-time clock, logging for up to 199 measurements and PC compatibility via the RS232 interface and Windows® compatible HI 92000 software.Specification:Range         0.00 to 50.00 FTU;50 to 1000 FTUResolution         0.01 FTU (0.00 to 50.00 FTU);1 FTU (50 to 1000 FTU)Accuracy         ±0.5 FTU or ±5% of reading (whichever is greater)Calibration         3 points (0 FTU, 10 FTU and 500 FTU)Light Source         infrared LEDLight Detection         Silicon PhotocellBattery Type / Life         1.5V AA (4) /approximately 60 hours of continuous use or 900 measurements; auto-off after 5 minutes of non-useEnvironment         0 to 50°C (32 to 122°F); RH max 95% non-condensingDimensions         220 x 82 x 66 mm (8.7 x 3.2 x 2.6")Weight         510 g (1.1 lb.)HI93703 is supplied complete with glass cuvette, batteries and instructions.HI93703C, includes meter, HI731313 maintenance kit (consisting of: cuvettes with  caps (2), HI93703-0 AMCO-AEPA-1 0 FTU calibration solution (30 mL), HI93703-10 AMCO-AEPA-1 10 FTU calibration solution (30 mL), HI93703-5 AMCO-AEPA-1 500 FTU calibration solution (30 mL) and cuvette wiping cloth), batteries, rugged carryingcase and instructions.

Air Quality MeterMULTIPARAMETER WATER QUALITY METER Multiparametric measure : Organic matter ( COD, BOD, TOC, TSS) specific compounds ( NO3, Detergents) All type of waters ( Natural water, raw sewage water, treated water, process water) Fast, reading in less than 1 minuteConvenient, easy-to-useWithout reagentUser friendlyTraditional measurement methods are not adequate to cope with the problems of water ressources and with environmental attacks. SECOMAM, in association withMr Olivier THOMAS of the Ecole des Mines d’ Alè s, has develop­ ped an alternative technique based on the analysis of UV absorption spectra of the samples.This technique brings about a considerable gain in term both of cost and time.Application fields : Control of organic and particulate pollutionProtection in the face of accidental pollution incidents - Process controlControl of the conformity of discharges in the receiving environment.Multiparametric : The PASTEL-UV is able to measure 6 parameters simultaneously and thus permits rapid characteri­ sation of the effluent. These parameters can be varied from one user to another.Rapidity : After the sample has been taken with a micro­ pipette and the quartz cuvette has been filled, ana­ lysis and reading of the results takes no more than a minute.This rapidity makes it possible to carry out a large number of measurements and to react in real time in cases of accidental pollution or of a process inci­ dent.Simplicity : The sample does not require pre-treatment ; if the sample is too concentrated, the apparatus itself will calculate the dilution factor to apply. PASTEL-UV can be used by personnael who do not possess special qualifications in chemistry.Economy : PASTEL-UV operates without reagents and without consumables ; the cost of running the machine is therefore independent of the number of analysis performed.Autonomy : Its autonomy in the field encompasses 100 measu­ rements and it can memorize up to 200 results.Traceability : All the data can be stored with a sample number, the user code, the site code and the date.Technical specificationsSpectral range 200 to 350 nmMeasuring cuvette 2 optical path : 5 and 10 mmWeight 5 kgDimensions 32 x 17 x 35 cmOutput Display screen ( 64 x 128 pixels) RS232C bidirectionalPower supply Internal Battery 100 readingsExternal 1 10/ 240V / 50/ 60HzPower 35 WattsReference 70MP0316
