Quantum Logic Model QL107 Pyrometer Data Logger is the ideal way to log and
play back temperature measurement data acquired with the Quantum Logic
hand-held Laser/Microcomputer based IR pyrometers.
This smart terminal weighs only 18 oz. (1/2 Kg), and measures 7 1/2 x 3 1/2 x 1" (19
x 7.6 x 2.5 cm). By means of an interconnecting cable supplied with the
QL107, it connects to an RS232 data communications port on the pyrometer.
Power is provided by 2 "AA" alkaline cells and a lithium back-up battery.
Due to the quick-disconnect design, users can take only the QL107, without
the pyrometer, to their office for data read-out at the end of a shift or
lengthy survey. Data transfer to an IBM compatible computer takes only
seconds via a serial COM port. Meanwhile, the pyrometer remains available
for other in-plant use.
A soft pouch is supplied with the Data Logger for transportation and
storage, and for convenient location at the operator's belt, or from his
shoulder, when taking data at the furnace.
High Storage Capacity
QL107 has memory sufficient to store approx. 40,000 data points - a
pyrometer-measured value plus location, time, date, and more.
The measured value to be logged is chosen by the operator using the
pyrometer's Function Selector Switch; i.e. true target temperature
(individual, minimum, maximum or average values), target emissivity, or
furnace wall temperature. Location is entered manually by the operator at
the start of a run. The time and date of each reading is recorded
automatically from the QL107's internal clock.
Stored data may be reviewed before being downloaded to a PC. Software for
downloading to the PC is supplied.

TUBETEMP Program
The QL107 incorporates a special software program called TUBETEMP. This
program is extremely efficient for the operator to use when the sequence of
the readings to be taken has been specified, as it is in most cases.
After entering a LOCATION description at the start of a run via the manual
keyboard, the operator keeps the QL107 in its pouch, without the need for
further manual entries. Each data reading is stored automatically by the
Data Logger when the operator presses a conveniently-located button on the
side of the pyrometer. Once entered, the LOCATION description is affixed
automatically by the QL107 computer to each reading, as well as the TIME and
DATE of the reading, without further intervention by the operator. As many
individual runs as desired, each with a different LOCATION designation, may
be stored, up to a maximum of 40,000 readings.
Each reading transmitted from the pyrometer is prefixed by a letter, "T" ,
"W", "E" ,"A" , "M" or "X", to identify that data measurement as a Target
Temperature reading, a Wall Temperature reading, an Emissivity reading, an
Average Temperature reading, or a Maximum Temperature reading,
respectively.
At the completion of a run, or runs, the stored data may be manually
reviewed, and then downloaded rapidly to an IBM-compatible PC, in ASCII
format, for subsequent storage, analysis and plotting, if desired.
