I need to find a refractometer prism sensor, with temperature compensation. To read the concentration of ingredients into fluids. Anyone knows WHERE to buy this device? need the sensor only, info@solucor.com
need the sensor only!
What device? Your link is for email.
"solucor.com" is a company in Costa Rica that makes bandsaw blades.

Hi,
look at this link:
This company has several spectrometer solutions.

Do you need to measure the concentration continuously in line with the process fluid plumbing? Expensive.
Or do you want to be able to measure samples, like this one? Much cheaper.

yes indeed
yes, I am looking for the low cost, sensor only, not the device.
looking for the sensor for reading refraction of a liquid sample (drop)
Ok, What would that sensor look like ?
A spectrum analysis device is for measuring color. A refractometer is for measuring the refractive index of a liquid. They are typically used to measure sugar or alcohol content in a solution.
The 'sensor' in a Brix Refractometer is usually a human eye and brain. I don't think there is any cheap way to get a human in good working condition.
How will you be interfacing the sensor?
And what do you define as low cost?
BTW, I use a simple hand held refractometer as mentioned by @johnwasser. It was only $15 or so, and it really quite easy to use.
That's a $15,000 ATAGO RX-5000i

I don't think they sell repair parts so if you wanted a part from one you probably have to buy the whole thing for $15,000.
Not sure how this relates to Arduinos.
You may have better luck asking in a forum for these types of devices.
These work pretty well. The sensor unit is separate from the internal PIC microprocessor, and can be removed.
The sensor itself a 3600+ element TCD1304 linear CCD detector, with integral total internal reflection prism, thermistor temperature detector and yellow LED illumination source.
Theory of operation is described here:
this is the part I need to buy, it is the whole sensor (prism, led, lend, ccd, ..) I need to find who makes this ?
That is exactly what is in one of the Milwaukee (or Hanna) refractometers. Ask the manufacturer, or buy the complete unit and take out the sensor assembly.
There is also small PCB that is required to interface with the CCD.
Where did you find that photo?

They say exactly what commercial unit to buy to get the part they used:
A Milwaukee MA871 refractometer was selected for its capability and simple design. At a price of approximately $100, it is an economical choice that provides a source of sensor optics.
yes. but I cant find who makes those in Asia! do you know any internet search tool to look ? thanks
