Designed to be simple, safe and
convenient to use
The ultra compact Pyropen has been specifi-
cally designed to fit into your pocket, just like a
pen, so that you can carry it with you anywhere
you go.
You simply aim, press the SCAN button and
read the temperature immediately. No fuss.
No need to focus and no special training.
The non-contact nature of the measurement
means that you can take the temperature of
moving, rotating, inaccessible or hazardous
objects. This makes the Pyropen particularly use-
ful for test, inspection and maintenance applica-
tions in industries such as food & beverage,
automotive, plastics & rubber, textiles, paper
& packaging, chemicals & pharmaceuticals,
HVAC, electrical, asphalting, plus many others.
The Pyropen L has all the features of the
Pyropen E, plus laser sighting for small or dis-
tant targets and adjustable emmissivity.
The Pyropen D has all the features of the
Pyropen L, plus a built-in memory for logging
up to 12 temperatures and the ability to per-
form PC based data acquisition. It is supplied
complete with PC interface cable and Calexlog
software disk.
High performance, low cost
The Calex design team have taken advantage
of the latest technology, not only to provide
an ultra slim design but to incorporate relia-
bility with high accuracy.
Advanced manufacturing techniques are used
to ensure that the Pyropen meets the highest
quality standards at low cost.
Each Pyropen comes with additional functions
such as maximum, minimum and average
temperature measurements. The Pyropen can
be LOCKED into the ON position if continuous
measurements are required. The last meas-
ured value can also be held for those situa-
tions where it is not easy to see the display
whilst measuring.
