Head-on PMT
Photon Counting Head H9319 Series
The H9319 series photon counting heads are designed to perform photon
counting by just connecting to a PC. The H9319 series includes a 25-mm (1")
diameter head-on photomultiplier tube, a photon counting circuit, a high-voltage power supply circuit, counter and a microprocessor. Data transfer, measurement time and other necessary adjustments can be controlled by commands from the PC through the RS-232C interface.
Since the H9319 series performs linearity correction by the internal microprocessor, it provides excellent count linearity within a range of ±1 % at
20 × 106 s-1.

Explanation
Set the number of 10 msec intervals to sum. Same as
integration time for 1 reading.
Set sequence of readings, where each reading uses
the integration time set with the P command.
Change the high voltage applied to the tube.
Re-set the default high voltage to the tube
Set the output of the user digital output line.
0: Low level output
1: High level output
Start the reading sequence
Start a continuous reading process. Will continue indefinitely until a STOP character (CR) is sent.
Start a reading sequence for each positive-edge TTL
transition applied to the purple stripe user line.
Start a reading sequence for each positive-level TTL
transition applied to the purple stripe user line.
