Ex-protection version of the iPR-B3Suitable for all applications in explosion-proof areasCertified according to European Classification ATEX II 1 G Ex ia IIC T4 GaPermanent inline real-time measurement of the concentration of dissolved solidsFully automatic process refractometer for direct measurement of dissolved solids, process monitoring and control. Principle of the critical-angle refractometer with sapphire prism and high-resolution photodiode array; no influence of color and opacity of the medium on the measuring result. Measuring head made of stainless steel, chemical resistant, food safe, hygienic, for process temperatures up to 120 C (with connected water cooling) and pressures up to 1 MPa.The explosion protection version of the process refractometer consists of an intrinsically safe, single-certified sensor, which is installed in the hazardous area. The measuring signals are routed to the non-explosive area via a special cable (maximum length 500 m) and connected to 4 zener barriers. The connection to the central control system is realized with a RTU Modbus or serial RS 485 interface.Alternatively, Schmidt + Haensch offers a control unit, which is also installed outside the hazardous area. The 7 touch screen is individually configurable. The measured data can be output via Ethernet as a 24 V or 4-20 mA signal or control a relay.

Permanent real-time concentration measurement Stand-alone sensor with integrated electronic Protection class IP 69K Configurable digital switches The automatically operating process refractometer iPR B measure the refractive index continuously and thus, the concentration of a binary or quasi-binary liquid mixture. The measurement is independent of light intensity from the light emitting diode (LED) and is free of signal drift, granting high precision and better process control. Colour, turbidity, undissolved particles or gas bubbles do not affect the measurement. The newly developed process refractometer iPR B replaces the well known model iPR Basic.The stand-alone sensor with integrated electronic ranks between the compact model iPR C and the full range model iPR FR. The new sensor comes with a measuring range up to 90% Brix (refractive index 1.52). It is suitable for almost all applications in the field of food production and pharmaceutical industries, but also for many processes in the area of mechanical and automotive engineering and chemistry. The stylish stainless steel housing of the sensor is partially equipped with a blue anodized air cooling jacket. This cooling jacket protects the electronic components from overheating in process temperatures up to 80 C. CIP cleaning at the prescribed temperatures is of course possible but the instrument must be switched off. The special design and electronic equipment makes it highly flexible and easy to use. The iPR B is equipped with two switch outputs to run, for example, a connected valve (max. 1A, 24 DC) or relay. With this feature is it also possible to control the cleaning of the measuring prism via a magnet valve. The iPR B measuring head can be installed in pipes, reactors, vessels and mixing tanks, using different weld-in flanges. Our preferred joint system is VariVent. It allows easy installation through a plug-in clamping method. Some processes may require cleaning of the sensor face.

Precise, fast and reliable Permanent real-time concentration measurement Compact sensor Galvanic isolated 4 20 mA output Excellent price-performance ratio Compact in-line refractometer iPR Compact with very short response time for continuous measurement and real-time process control with one analogue data output. Its characterized by minimized dimension and weight and has an excellent price-performance ratio. The iPR Compact allows the inline, real-time refractive index, Brix or concentration measurement to monitor and control the concentration of dissolved solids in solution or liquids in process. The compact stainless steel measuring head with YAG Prism is equipped with an integrated electronic for direct connection to supervisory system or PC.

Permanent real-time concentration measurement Sample temperatures up to 150 C Configurable digital switches User-defined scales programmable Liquid-based or ultrasonic cleaning devices The automatically operating process refractometers iPR FR (Full range) measure the refractive index continuously and thus, the concentration of a binary or quasi-binary liquid mixture. The measurement is independent of light intensity from the light emitting diode (LED) and is free of signal drift, granting high precision and better process control. Colour, turbidity, undissolved particles or gas bubbles do not affect the measurement. You can choice from 2 wide measuring ranges. The refractometer iPR FR is a stand alone process sensor with integrated, iluminated display , which does not require an external electronic unit. Its special design and electronic configuration makes it highly flexible and very easy to operate. The programming with a Windows software is also very easy. Optional a Data Logger is available. The stainless steel measuring head is: IP69K protection class tested by TV! Resistant against chemicals Suiting food regulations and CIP conform (pipe pig use possible)

Digital handheld refractometer with 5-digit, full view LCD screen, which displays results in 2 seconds. Measurement of liquid media from low to high viscosity. Handy design, simple operation, reliable, automatic temperature compensated brix value within +5 to 70 C.Various models are available, e.g. for applications like honey, wine, saline, glycol or DEF. For more information check the technical specifications.

The digital, fully automatic spectral refractometer ATR-L consists of an electronic unit separated from the stainless steel measuring unit. Dispersion measurement at 7 wavelengths over the full visible range. A sample volume of 0, 3 ml is sufficient for measuring. The refractometer is equipped with a Peltier thermostat (no external water bath/thermostat necessary).Multiple wavelength digital refractometer for dispersion measurements.Refractometers are widely used in food, oil, fuel and other industries to measure the concentration of components in order to monitor and control the fabrication process. They measure the critical angle of total reflection and calculate the refractive index from this value. The refractive index of a substance depends on the wavelength of light and usually increases towards shorter wavelengths.

Compact laboratory refractometer. The new ATR-BR is an critical angle refractometer for the measuring of liquid media from low to high viscosity, and independent of opacity and color. The ATR instrument are available in a variety of configurations for laboratory and production quality control.The newly designed casing offers more space for a bigger LCD display and a splash proofed foil keyboard. Batch numbers can be entered directly and also simple form may be created and printed out.4 special scales, one of them being programmed as Brix scale by the factory, allow various applications in production and laboratory. The software of the ATR-BR, designed close to the practice makes it possible to take the mean value and to determine standard derivation and adjustable measuring delay for special measurement in dependence of the temperature. All functions may also be controlled via PC using the remote control program.
