- No maintenance
Descrição
The UR62 digital refractometer is a probe designed for simple installation in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with basic accuracy. The UR62 will signal to the process when concentration is outside of specifications or has reached its target end point by means of analogue 4-20 mA output. The probe is easily set up and configured through a PC or portable computing device using its built in RS485 interface. It can also be connected to the optional RC-24 touch screen operator display unit. The analyzer does not have any drift in the time so that it does not need any adjustment vs the laboratory: after the initial configuration during start up, the operators in the plant do not have to touch the system anymore. Due to the optical technology, the equipment is virtually no maintenance: the robust construction with 316 stainless steel and IP67 protection, allows the installation in any aggressive environment using various Maselli mounting adapters.

It also features a user programmable scale for specific applications. The URX1 will signal to the process when concentration is outside of specifications or has reached its target end point by means of analogue and digital interfaces (Profibus DP is available as an option). The analyzer does not have any drift in the time so that it does not need any adjustment vs the laboratory: after the initial configuration during start up, the operators in the plant do not have to touch the system anymore. Due to the optical technology, the equipment is virtually no maintenance: the robust construction with stainless steel case and IP67 protection, allows the installation in any aggressive environment using various Maselli mounting adapters including weld ends, flanges and DIN 11851.
LABORATORY REFRACTOMETERS
Maselli offers multiple accuracy options to suit your measurement needs for industrial manufacturing applications.
LR05 – Lab Refractometer
BRIX / nD / HFCS / USER SCALE

Vantagens
- Robust stainless steel case
- Accuracy based configuration
- Brix, nD and User scales
- Wide range of applications
- No maintenance
Descrição
The LR05 laboratory refractometer has been designed to be accurate, robust and easy to use. The project has been developed using state of the art technology, which guarantee a high level of precision and reliability, such as the sapphire prism, the LED long-life light source and high-resolution digital optical CCD sensor. The intuitive software interface is available on a wide 6.5 inches touchscreen panel PC which allows easy interface by means of USB ports (ethernet available). The LR05 unit measures the sample refractive index calculating its concentration that may be displayed in different ranges: Brix, nD, % concentration. The LR05 may be delivered in 3 different models: standard, high and super accuracy. All the measurements are automatically temperature compensated: an optional flow cell is available for corrosive products. Main application fields are within industrial laboratories in the food, chemical, pharmaceutical and textile sectors.
LR02 – Lab refractometer
BRIX / nD / HFCS / USER SCALE

Vantagens
- Basic accuracy
- Robust stainless steel case
- 2 decimal place resolution
- Portable with batteries
- Software for data analysis
Descrição
The LR-02 refractometer has been designed to be accurate, robust, compact and easy to use both in the laboratory and out at the line. Thanks to its battery power supply and carrying handle, it is easy to transport and use without being connected to a main power supply. Its waterproof keyboard and its stainless steel structure mean it can be safely used directly in the production area. By simply lowering the cover, without pushing a single button, the LR-02 “Easy Start” refractometer measures the sample’s refractive index, calculates its concentration (Brix o User), displays the information on an LCD unit with back lighting and sends the recorded value to an optional external printer or to a PC. The project has been developed using state of the art technology, which guarantee a high level of precision and reliability, such as the sapphire prism, the LED long-life light source and high-resolution digital optical CCD sensor.
LABORATORY SPECTROPHOTOMETERS
A unique solution to automatically measure color and lycopene in tomatoes.
LC01 – Spectrophotometer
COLOR INDICES / LYCOPENE

Vantagens
- Capable to calculate color and lycopene content
- Measurement of the sample as it is
- Quick results
- Calibration with standard BCR tile
- Software for data analysis
Descrição
The Maselli LC01 Colorimeter + Spectrophotometer is a laboratory instrument developed to measure the color indices a, b, a/b and L, as well as the Lycopene content in tomato products. It has been designed to be accurate, robust and simple to use: the stainless steel enclosures and waterproof display permit the LC01 to also be used in the processing area The LC01 is able to quickly measure the sample as it is introducing a new innovative method to measure directly the lycopene content of the tomatoes during each stage of the processing. An intuitive software and touch-screen display simplify the interface for all the operations related to graphics, data storage, transfer and printing features. While the equipment does not need frequent calibration, it can be checked using the classic tomato standard BCR red ceramic tile, while using its PVC sample holder with optical glass window for the measurements.
TOMATO QUALITY STATION
Automatic system designed to assess quality control parameters of incoming tomatoes directly from the truck in the fruit receiving area.
SV01 - Quality station
QUALITY CHECK OF THE INCOMING TOMATOES

Vantagens
- Turn key solution
- More than 200 installations worldwide
- Robust sampler
- Fully automatic cycle (5 minutes / truck)
- Software for data analysis
Descrição
The SV01 station is installed at the receiving area of the tomatoes processing plant to evaluate the quality of the incoming raw fruit. The station is a turn key modular construction which consists of a truck sampler, a prefabricated module with all the elements for the check of the tomatoes and a PC handling automatically the whole system. All the cycle is very quick and only one operator can process 1 load every 5 minutes making it easy the circulation of the trucks into the factory. Each plant may personalize the software with the parameters to be checked: in average, the system is determining the percentage of waste (inerts, fruit defects, fruit illness) and the physical parameters such as Bx, pH, color and lycopene. The data gathered, which may be printed and stored in a database, not only provides a more accurate economical evaluation of the delivered fruit, but also makes it possible to send the various loads to the most appropriate processing lines and can be used to help with the making of agronomic decisions for the cultivation of the fruit in the coming years.
TOMATO MODULAR ELEMENTS
Grinding station to produce the juice for the analysis of Brix, pH and color of tomatoes.
TR01 - Tomato Analyzer
BX/ PH / COLOR ANALYSIS OF THE INCOMING TOMATOES

Vantagens
- Modular sensors (upgradable in steps)
- Automatic grinding of the tomatoes
- Proven construction
- Easy service
- PC to handle the system operation
Descrição
The TR01 grinding unit is one of the most important elements of the Maselli SV01 quality control station for the check of the quality of the raw tomatoes delivered at the processing plant. In its maximum configuration, the TR01, after having reduced the tomato to juice, can automatically determine Brix, pH, color and the quantity of lycopene of the sample. The “all in one” solution means that the installation times and costs are reduced to an absolute minimum and it makes transfer and reinstallation in other areas quick and easy: all together, these functions make this a unique system easy to be handled and serviced. The TR01 can be delivered in 2 different configurations:
- when integrated in the SV01 station, it is directly controlled by the PLC;
- when delivered as a stand alone unit, it comes with a remote pushbutton panel so that it can be activated an interfaced with the data acquisition system.
