All WTW Technical buffers are certified accurate and are NIST/DIN traceable   The new buffer bottles from WTW: easy to dispense easy to use reliable calibration

The pH/mV and ionmeter pH/ION 340i offers the highest degree of flexibility possible. For pH measurements the instrument can be calibrated manually or automatically and offers simultaneous display of pH and temperature. For measurements with ion-selective electrodes the pH/lON 340i offers concentration display in mg/l. Direct display in mV to ±999.9 mV in 0.1 mV steps; and to ±1999 mV in 1 mV steps. Of course, even in these…

The FS 3700 Automated Chemistry Analyzer is an advanced continuous flow analyzer designed to improve laboratory productivity by automating wet chemistry test procedures.

The OPTi ® Digital Handheld Refractometer is a truly portable instrument that fits in the palm of your hand, and is capable of giving you over 10,000 readings on just 2xAAA batteries. It features a stainless steel prism dish which rapidly stabilises sample temperature, a durable IP65 rated body, and a clear LCD display. 

The Aurora 1030C TOC Analyzer processes aqueous samples for analysis of the total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC) content of the samples. Samples containing 100 ppb to 30,000 ppm of organic carbon can be analyzed. The Aurora 1030C supports USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, and EU Methods. Depending upon the protocol employed, up to 300 samp…

The 910 colorimeter is a rugged, waterproof, single parameter instrument for the measurement of COD (chemical oxygen demand).   The EPA-approved COD test is useful for performing rapid, frequent monitoring of treatment plant efficiency, and results allow quick response to changing conditions in the waste stream while the traditional BOD5 test takes 5-days to determine results. The instrument features a large, backlit dis…

Analyze the most challenging real-world samples with complete confidence using the Model 1020A TOC Analyzer. Its advanced catalyst technology and approved combustion method is the best analytical technique for accurate and reproducible measurement of dirty, salty, or particulate-laden samples. With its easy operation, reliability, space-saving design, wide linear range, and outstanding accuracy, the Model 1020A delivers unmatc…

The Flow Solution® IV+ (FS IV+) is a powerful automated chemistry analyzer for performing high throughput continuous flow ion analysis methods. The FS IV+ supports and performs two types of continuous flow analysis techniques: segmented flow analysis (SFA) and flow injection analysis (FIA). The FS IV+ consists of a 360-position autosampler, a 24-channel peristaltic pump, a power base module (with 4 independently controlled hea…

pH 315i, pH 330i, pH 340i Robust Waterproof (IP 67) Large silicone keys WTW handheld pH meters are optimized for use on-site and field use, but can also be used in the laboratory. In particular the pH 340i, with its optional line power supply and serial interface, is suitable for applications in which precise measurements are required both in the laboratory and the field. WTW handheld pH meters are available in three ve…

The inoLab® benchtop meters of WTW, Weilheim, Germany, have been relaunched in April 2004. pH, DO, conductivity and multi-parameter instruments show not only a new colour but also enhanced functions and additionally, the family will have two new members, the new inoLab® pH/ION 735 and the high-performance inoLab® pH/ION/Conductivity 750 with two high-impedance inputs and an 8-pin socket for conductivity cells. So for almost  a…
