Bonjour,

Pour notre part je repondrais pour nos analyseur en ligne.

Nous utilisons la colorimetrie pour un large nombre de paramètres, Chlore, Phospahte, Silice, Fer, Cuivre, Duretée...

Nos réactifs sont disponibles au choix en poudre à préparer sur place, accordant plus de 24 mois de stabilité.

Ils sont également proposés en pret à l'usage sous forme liquide. Dans ce cas leur durée de vie est comprise entre 6 mois et 1 an suivant le paramètre mesuré.

j'espère répondre au mieux à votre demande, et restons à votre entière disposition pour tout complélent d'information.

Au plasir d'échanger prochainement,Yann Bouvier.

TRACE Narwhal RS1 Datasheet

Uniquely specialized to be the most adept of its kind, this colorimetric analyzer is engineered at the intersection of precision and economy. Every detail has been designed to perfect performance and user experience. There’s simply nothing else like NARWHAL ™ on the market. NARWHAL automates time-consuming lab-based tests for an array of water quality applications. Setting up is simple, and the 7” intuitive touch screen allows for easy customization and data monitoring – including real-time indication of process conditions. With faster turnaround, higher testing volume, and increased precision and reproducability, NARWHAL makes a splash both in reducing human error and increasing productivity in the lab. The RS1 performs fully automated colorimetric measurements in a process setting utilizing up to three reagents. 7” intuitive touch screen display with easy-to-use software allows users to calibrate and view data. Automatic 2-point calibration maintained with self-referencing feature. The interval between &Yx% A?( I??6b` Self-cleaning design and long life LED minimize required maintenance. Theory of Operation Features & Bene? ts 2u?e?% A?F0 valve and pump for ease of maintenance and high-precision measurements. Low reagent and sample usage (ex: optional 2.5 L reagents for 3 months silica). Multitude of diagnositc features that alert users of process upsets. Standard data outputs include MODBUS, 4-20mA, USB to CST Software, and removable SD card. The RS1 is designed to perform fully automated colorimetric measurements and deliver the product of the chemical reaction to an analysis cell in a process $bY?h% A?$p?Q2?? of sample from a stream and mixes it with up to three reagents in succession. After each reagent addition, a mixing cycle is performed followed by a variable reaction delay. Once the reagent addition process is complete, 16e% A???(huI? where the compound of interest can be determined via an absorbance measurement. The RS1 is designed to be mounted near the pipeline containing the sample of interest which is retreived from the pipeline via a fast loop. The RS1 also utilizes a grab sample chamber to make analyzing small sample volumes quick and easy. 531 AXMINISTER DR | FENTON, MO 63026 | 636.305.0666 | SALES@CUSTOMSENSORS.COM | CUSTOMSENSORS.COM DIMENSIONS:42 x 9 x 8” 7 ” T O U C H DISPLAY SAMPLE OUTLET SAMPLE INLET WASTE REAGENTS / CALIBRATIONSOLUTION GRABSAMPLE SYRINGE PUMP MEASUREMENT CELL SAMPLE HEATER LED LIGHT SOURCE PHOTOMETER ROTARY VALVE 531 AXMINISTER DR | FENTON, MO 63026 | 636.305.0666 | SALES@CUSTOMSENSORS.COM | CUSTOMSENSORS.COM ___________________________________________________________________________________ _______________________________________________________________________________ TRACE Analysis Sarl – 548, Chemin de Simandre, 38850 Villages du Lac de Paladru, France - R.C.S.
