Technical Data

The Fluke Calibration 525B

Temperature/ Pressure Calibrator

gives you a workhorse combina-

tion of high accuracy and broad

functionality for temperature and

pressure instrument calibration.

Compact and economical, the

525B has an interface for auto-

mated calibration, providing wide

workload coverage in instrument

shops and calibration labs, as

well as in ATE applications.

The 525B is the most

accurate Fluke Calibration

temperature calibrator, sourc-

ing and measuring a complete

range of RTDs, thermocouples,

and the YSI 400 thermistor. It

also measures pressure cover-

ing common ranges from 1 inch

(6900 Pa) of water up to 10,000

PSI (69 MPa) using the Fluke 700

Series and 525A-P Series Pressure

Modules. Plus, the dc voltage and

current speciﬁcations of the 525B

enable you to calibrate other

process calibrators and a wide

variety of other instruments with

accuracy that rivals any calibrator

in its price range.

Key features:

•

Simulates and measures all

ANSI thermocouples, as well

as L and U types, and provides

cold junction compensation to

enable calibration of a wide

variety of thermocouple instru-

mentation.

•

Direct input for storage of

ITS-90 RTD constants.

•

RTD source uncertainties to

0.03 °C.

•

Direct measurement of all

Fluke 700 Series and 525A-P

Series Pressure Modules cover-

ing the most common pressure

ranges from 1˝ H

to 10,000 PSI.

•

Converts easily to any pres-

sure unit directly from the

front panel or through remote

communications.

•

Sources dc voltage and current

for multifunction workload

coverage, enabling calibration

of data loggers, strip chart

recorders, multimeters, and

other industrial instruments.

•

Supports automation using Fluke

Calibration’s MET/CAL

Plus

Calibration Management

Software or custom automated

programs with standard

RS-232-C and IEEE-488

interface.

•

Eight user programmable

setpoints allow quick recall

of values for Zero, Span and

linearity checks during

calibration.

•

Programmable setpoint dwell

times for automated calibration

and troubleshooting.

•

Selectable internal or external

CJC (Cold junction compen-

sation) provides you with

the ability to make exacting

thermocouple measurements

using remote junctions.

•

Easy ﬁve-way binding posts for

low-loss convenient hookup.

Banana plug, screw terminal,

spade lug,

wraparound terminal, wire

pass-through terminal.

•

NIST-traceable calibration with

data is included.

At home in the cal lab

The 525B is a compact bench

instrument well suited for

traditional calibration labora-

tories with a large temperature

workload. Its 0 to 100 V output

and 0 to 100 mA current capa-

bilities—plus its ability to serve

as a highly-accurate pressure

standard—make it a versatile

performer.

Filling the gap in the

instrument shop

In process plant environments,

instrument shop technicians

responsible for maintaining the

equipment pool need to calibrate

and repair a wide range of instru-

ments, transmitters, ﬁeld calibra-

tors, P/l converters, transducers,

and temperature probes. With

its ability to simulate almost any

temperature sensor, precise pres-

sure monitoring capability, and

dc voltage and current accuracy

rivaling any calibrator in its price

range, the 525B ﬁlls the gap

between lower accuracy hand-

held ﬁeld calibrators and more

expensive high-end multifunction

calibrators.
