Resistance thermometry bridges
By using internal or external standard resistors (model CER6000), resistance thermometry bridges measure resistance ratios
with high accuracy, which are indicative of the temperature, among other things. Due to their high accuracy, these instruments
are not only used in the eld of temperature measurement, but also in electrical laboratories.
ASL equipment is used for research, primary and secondary
calibration verication, process monitoring, sterilisation and
validation work by some of the world’s most demanding end
users in the Aerospace, Pharmaceutical, Oil and Gas, Power
and Distribution, Electrical and Electronic industries, and all
International Standards Laboratories including the National
Physical Laboratory in the UK, BIPM in France, PTB in
Germany, NIST in the USA, AIST in Japan and NIM in China.
Our thermometry bridges cover a range of single and multi
channel applications and are used extensively by national
standards laboratories around the world. We oer also high
accuracy precision digital thermometers for scientic and
laboratory use.
Moreover ASL provides a full range Platinum Resistance
Thermometers (PRT) for use in every application from
standards calibration to site temperature measurement. If our
“o the shelf” range will not suit your needs we are able to
supply custom manufactured thermometers to almost any
specication. We also provide a range of Standards Resistors
for use when calibrating Platinum Resistance Thermometers.
