I will have to look into the AP meter. Maybe the technology is something we can look into as well.

All refractometers are dependent on the refraction of light which is based on the refractive index (RI) of the solution being measured. Manufacturers of digital refractometers make multiple variations of the same product. When RI is converted to Brix it is based on a sucrose solution according...

As an employee of a company that makes a digital refractometer, the biggest challenge we face is when the user uses water that is not purified. To the point that we buy DI water and re-package to be supplied with the meter. Overall, I would recommend buying a bottle of distilled water and use...

There are typically three filters for an RO system. One is a cloth/fiber that removes the particulate. The other is a carbon filter, which removes chlorine and odors. The last is the RO membrane itself. The RO membrane is the one that removes the salts/ions from the water. The sediment and...

A couple of things to note. From my experience an RO system will produce water that is about 30 uS/cm or 15 ppm TDS (EC/2). There are not a lot of salts left in the water. It is close to zero. For a lab that needs high purity water, it is common to filter incoming water by RO to remove the...

Thanks for sharing the video. It was very helpful.

For a homeowner I would still recommend pH 7 and 4 for calibration. The swimming pool is slightly alakline being ideally between pH 7.2 ot pH 7.6. That is pretty close to the isopotential point of pH 7. pH 10 is not a very stable buffer. The carbon dioxide in the atmosphere diffuses into the...

Swimming pools should be maintained between pH 7.2 to 7.6. The reason is that when you add chlorine into the pool (whether added as a liquid or generated by electrolysis) it will exist in two forms (OCl- and HOCl). It is the hypochlorous acid (HOCl) that is the effective sanitizer. So as pH...

It looks like you have two channels. Did you try the probe on the other channel? From a website it shows that the temperature is up to 572 oF. For that temperature it should be a thermocouple. With a thermocouple there are two wires of different metals twisted together that produced different...

I have been very happy with my Pit Boss pellet grill. It is pretty versatile. You can set at a smoke mode that maintains a variety of low temps from 180 to around 230 oF. It has other temperature setting in which I find myself using 350 oF frequently. Recently I picked up a flat-top griddle off...

They are interesting. From talking with people at tradeshows they work well with semi-solids (i.e. soils, cheese). There was Sentron and IQ Scientific. I believe some of the major names in process (E&H, Knick) might be using them for food where glass is a big issue in continuous monitoring...

Thanks!

Thanks! When it comes Very good information. The pH charts listed on the buffer bottles/sachets are useful to calibrate at a temperature that the instrument will be used at. There have always been the argument that the actual pH of the solution is different at different temperatures. ATC...

Hello Martin, Back on the forum again. I use to be with Hanna and sent your a Halo BT meter. I am now with Milwaukee. I hope to connect in the future. Paul

Thanks, definitely cannot beat the ease of use of a refractometer. The Applications team that I managed at Hanna had some enthusiast that did all grain. Back in the day I would use the wort extract so I am looking forward to going all grain.
