HPLC Refractive Index Detector VARIAN RI-4

Determine the refractive index everywhere Developed for a wide range of applications, ranging from c (more)hecking the sugar concentration in beverages to checking the hydrocarbon content of fuels, METTLER TOLEDO's line of portable refractometers provide accurate and repeatable results in seconds, displaying them in units of measurement appropriate. Portable digital refractometers can be used on a flat surface or dipped directly into the sample for quick and easy measurements. Accurate results During the measurement, Refracto automatically determines the temperature and corrects the refractive index back to a standard value of 20 ° C (or any user-defined temperature). This ensures accurate results, regardless of the ambient temperature. Clarity and simplicity The keyboard and menu structure make operation simple and efficient. The results are clearly displayed on the backlit LCD screen. The Refracto portable refractometer stores up to 1100 results and includes information such as sample ID, unit of measure, date and time and much more. Simple data management The measured values ​​can be viewed directly on the portable refractometer. Exporting results from Refracto to EasyDirect ™ refractometer and density meter software offers even more flexibility. With just a few clicks, you can review and filter results on your computer and create graphs to track samples over time and better control processes. Reports can be printed from the software or directly from the instrument.

The H315 waterproof scale Made to work in high humidity conditions and even direct contact with wate (more)r. Designed for precision measurements, making it used in situations where weighing readability is crucial. The power of steel The use of stainless steel for the construction guarantees you a long life for the balance. It is not afraid of contact with moist objects or accidental splashes. The robustness and strength of the design of the platform scales makes it possible to weigh large objects, such as pallets of goods. The stable platform is resistant to vibration, which is important when weighing large objects. Not just weighing But also parts counting, percent weighing, animal weighing and peak hold. The power of H315&rsquo;s working mods. Do you require fast and repeatable weight measurement under difficult conditions? The H315 scale is made for that! It has been with us for years, and will stay for a long time to come The LCD display has accompanied us for long years. During this time it has proven its reliability. It guarantees the readability of the result from many angles and is energy efficient. Inner power No access to mains power? Power failure? No problem. Thanks to its internal rechargeable battery, the H315 scale allows many hours of operation without mains power (up to 7 hours). Battery power supply is available at an extra charge. As standard, the scale is equipped with a RS232 cable, to which you can connect most of the accessories from our range.

Highest Precision The E1 class mass standard of 100 g is a cylindrical standard with the highest pre (more)cision, designed for applications requiring accurate measurements. Made of high-quality materials to ensure stability and measurement accuracy. Ideal for laboratories, research centers, and anywhere precision weighing is needed.

The HX5.EX scale is a modern weighing instrument assuring fast and reliable measurement in hazardous (more) areas classified as zones 1/21 and 2/22. To ensure precision and excellent measurement repeatability, high quality electronic components are used. The weighing platforms offered in wide range of dimensions and maximum capacities, this combined with excellent metrological parameters enables easy selection of an instrument that meets the most demanding requirements. Standard version of the scale is equipped with 2 serial, intrinsically safe RS232 communication interfaces, and with one RS485 interface. They facilitate cooperation with equipment intended for operation in hazardous areas. Possibility to add digital inputs/outputs extends the range of instruments compatible with the indicator by automatic elements compliant with ATEX directive. More demanding customers can use the IM01.EX module, installed in the safe area, which extends the available connectors by Ethernet, USB, 4-20mA/0- 10V analog outputs, Profibus DP and additional digital inputs/outputs. This enables cooperation with external devices: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. Scale operation requires use of a dedicated PM01.EX power supply, which is not a standard scale component. To operate the scale, order a selected type of the dedicated intrinsically safe power supply. Power supply types: PM01.EX-1 - power supply for operation in ATEX area. Used when it is required to connect the power supply to voltage source placed in hazardous area. PM01.EX-2 - power supply for operation outside ATEX area. Used when power supply connection to voltage source is carried out outside hazardous area. Complex software enables carrying out many tasks connected with mass measurement, e.g. parts counting, checkweighing and statistics. The scales feature user-friendly graphic interface, which can be customized using widgets. This and the large colour display of high resolution guarantee easy and clear transmission of data on current process. Colour bar graph significantly influences performance by signalling whether the weighing result is within declared thresholds or not.
