The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples.

A photomultiplier tube is a device used to measure very low levels of light. It’s a common tool of particle physics when trying to detect just a few photons. It turns out that running a tube at ...

It utilizes a technologically advanced photomultiplier tube (PMT) that amplifies ATP (adenosine triphosphate) allowing detection of lower levels of microbial and organic contamination. This is a ...

The device includes a voltage reference generator to initiate the chemical reaction and a photomultiplier tube (PMT) to measure the emitted light. The PMT outputs a current which is then converted ...

Up to four photomultiplier tubes (PMTs), each detecting ... The photosensor and PMT signals are converted into 14-bit pixel values that are then assembled into high-resolution images.
