able to advise you on the correct returns procedure.
Any item returned to Land Instruments International should be adequately packaged to prevent damage
during transit.
You must include a written report of the problem together with your own name and contact information,
address, telephone number, email address etc.
Design and Manufacturing Standards
The Quality Management System of Land Instruments International is approved to BS EN ISO 9001 for
the design, manufacture and on-site servicing of combustion, environmental monitoring and non-contact
temperature measuring instrumentation.
Approvals apply in the USA
This instrument complies with current European directives relating to Electromagnetic
Compatibility 89/336/EEC and Low Voltage Directive 73/23/EEC.
Operation of radio transmitters, telephones or other electrical/electronic devices in close proximity
to the equipment while the enclosure doors of the instrument or its peripherals are open, may cause
interference and possible failure where the radiated emissions exceed the EMC directive.
The protection provided by both CE and IP classications to this product may be invalidated if alterations
or additions are made to the structural, electrical, mechanical or pneumatic parts of this system. Such
changes may also invalidate the standard terms of warranty.

1 Landcal Blackbody Source Type P80P
1.1 Introduction
The LANDCAL blackbody source type P80P is a variable temperature, portable
black body radiation source designed for use at temperatures up to 80°C
(175°F).
The source is a primary standard black body for the high precision calibration
of radiation thermometers over the range -10 to 80°C (15 to 175°F). When
the set point temperature is reached, the output from the thermometer under
test is compared with the temperature of the source as measured by an
optional Platinum resistance thermometer whose calibration is traceable to
National Standards.
When used in conjunction with the Platinum resistance thermometer which
is supplied complete with a UKAS (United Kingdom Accreditation Service)
calibration certicate, high precision is obtained. Alternatively the source can
be used in three other ways.
1) If traceability to National Standards is required to a larger value of
uncertainty a UKAS certicate of calibration for the source can be
supplied. The relationship between the indicated temperature on the
controller and the radiance temperature as measured by a secondary
standard radiation thermometer is reported.
2) The temperature of the source can be measured by using a radiation
thermometer of traceable calibration. This method of calibration can
be described as calibration by comparison with a standard radiation
thermometer. This method of calibration usually results in the most
accurate as errors due to temperature gradients and non-black body
conditions are eliminated.
3) If traceability to National Standards is not required, the source can be
used without any certication. From previous work the temperature,
as shown on the controller indication, has been found to agree with the
radiance temperature to within ±4K (±8°F).
The source provides a wide angle target which makes it ideal for use with
both xed installation and portable, hand-held thermometers.
To make the lining up of LAND xed installation radiation thermometers
simpler, an optical bench assembly is offered as an optional extra. When the
source is stood on the optional transportation case, the bench to mid target
dimension equals that of the optical bench assembly.

1.2 Safety
Every effort has been made during the design and manufacture of this source
to ensure that it meets National and International standards of product safety.
However, great care must be taken by the user at all times when operating
and maintaining sources that are capable of achieving high temperatures.
Warning
To avoid the possibility of electric shock, never expose the
elements, terminals or other electrical components when the
calibration source is connected to the mains supply. After
completion of a repair, replace all safety plates before switching
on the calibration source.
To avoid the possibility of burns, never attempt to dismantle the
calibration source until it has cooled to a safe temperature. This
may involve an overnight wait.
This calibration source contains no asbestos. The alumina-
silicate (ceramic bre) materials used in this instrument release
dust when disturbed which may, in some individuals, be an
irritant to the skin, nose and throat.

2 Description
The LANDCAL blackbody source type P80P comprises a cylindrical closed end
tube (cavity) approximately 160mm/6.3in long with an internal diameter
of 50mm (2.0in). The cavity is manufactured from Aluminium which is
blackened and the closed end is angled at 120° to increase the emissivity
value.
The cavity is heated or cooled using Peltier elements. The temperature is
controlled by a platinum resistance thermometer connected to a 3-term
digital controller having a ±0.1°C or ±0.1°F resolution.
An optional standard platinum resistance thermometer possessing a traceable
(UKAS - United Kingdom Accreditation Service) Certicate can be inserted
into the cavity from the front of the source and used to determine the true
(radiance) temperature.
