ISO 9001 Manufacturer
Specification Sheet, SS-PTC-125
The PTC-125 is the newest member of the well-known JOFRA PTC
family that can meet any type of industrial temperature calibration need
within the -90 to +660°C (-130 to 1220°F) temperature range.
Standard features
Great temperature homogeneity
The PTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format.
The JOFRA PTC-series features our well-known active dualzone heating technology. Each heating zone is independently controlled for precision temperature calibration. The
homogeneity in the lower part is close to that of a laboratory
liquid bath. The lower zone ensures optimum heat dissipation throughout the entire calibration zone. The upper zone
compensates for heat loss from the sensor-under-test and
from the open top. This design also eliminates the need for
extra insulation of sensors-under-test and makes it possible
to calibrate any type of mechanical sensors.
Wide temperature range
The PTC-125 performs calibration over a wide temperature
range starting from -90°C and up to 125°C (-130 to 257°F).
This makes it possible to perform calibration of sensors in
applications ranging from ultra-coolers to sterilization sensors (SIP).
Fastest temperature calibration
Time is money! This is why all the new PTC calibrators
heat and cool faster than all other calibrators on the market.
This saves you both in production downtime and general
calibration costs.
NEW!
Plug & play
USB connector for communication
Another PTC feature is the USB connection that facilitates
easy communication with the calibration management software JOFRACAL. The USB connection also supports easy
download of future firmware upgrades.
The USB connection provides fast and easy access to all
laptops without the need for RS-232 to USB converters.
Future-proof through e.g. a flash capability for easy firmware upgrades as well as already integrated LAN communication, SD-card slot and USB host connectors.
Efficient cooling technology
The PTC-125 with both heating and cooling capabilities
features the FPSC (Free piston stirling cooler) as the cooling
source.
It is much more efficient than thermo-electric (Peltier) coolers.
Easy to read & user friendly
The new 5.7” full color VGA display is large, bright and very
easy to read – even from a distance. The main temperatures, like SET, READ, TRUE and SUT (sensor-under-test),
are always displayed at all stages of the programming or
calibration procedure.
The navigation is menu-driven and very logical to use and
the display shows important information needed for the
current function in use. The communication window pops
up and is followed by discrete sound messages.
Intelligent reference sensor communication
The JOFRA STS-150 intelligent reference sensor contains all
individual calibration data regarding the sensor.
This means that the time-consuming coefficient
downloading sequence with risk of errors is no longer necessary. As well, the user can change the reference sensor and
be up and running immediately.
With these intelligent reference sensors, AMETEK has eliminated a source of error and the system is now a fail-safe plug
& play calibration system.
Intelligent recalibration information, IRI
In order to comply with ISO, SOP’s and FDA, it is imperative that the calibration equipment never exceeds the
expiry date of the calibration certificate. The PTC calibrator is, when switched on, constantly checking calibration
dates on the calibrator as well as for the connected STS
sensors. If the calibration period has expired, a warning
will appear in the display. This feature prevents costly
consequence evaluation.
The display contains detailed information at a glance, such
as:
• Stabilitystatus
• Realtimeclock
• Serialnumberofreferencesensor
• Sensor-under-teststatus

Easy to carry
A calibrator is carried from one job to another and therefore it needs to weigh as little as possible. AMETEK has
designed the PTC calibrators to be lightweight and easy
to carry, without compromising quality, durability or functionality.
The PTC-125 weighs only 15.2 kg, making it one of the
lightest ultra coolers on the market.
SET-Follows-TRUE (Models B & C only)
The “SET-Follows-TRUE” mode makes the instrument tune
in to the temperature reading of the external reference
“TRUE” meets the desired “SET” temperature. This feature
is important when it is critical that the temperature of the
calibration zone matches the desired temperature when
measured with accurate external reference sensors.
Reading of sensor-under-test (Model B only)
Model B is equipped with a built-in accurate measuring circuit for sensor-under-test (input), which enables measurement of virtually any type of temperature sensors including: Resistance thermometers (RTD), thermocouples (TC),
transmitters, milliamps (mA) and thermostats.
PTC calibrators can be user-programmed from the
keyboard for fully-automatic sensor calibrations. Once the
unit is programmed, the instrument is self-operating and
performs the configured calibration routine. All calibration
data and results are stored and can be read on the display.
Enhanced stability
A stability indicator shows when the PTC calibrator has
reached the desired temperature and is stable. The user
may change the stability criteria for the external reference
and the sensor-under-test quickly and simply. The stability
criterion is the user’s security of a correct calibration.
A count-down timer is displayed next to the temperature
read-out.
Specially-designed carrying case
AMETEK has designed an all-in-one carrying case that
makes it possible to store the STS reference sensor in the
carrying case with optimal physical protection. There is
room for inserts and insulation plugs to cover all sensorunder-test dimensions and compartments for the wires,
manuals, certificates, plugs, insert tools, etc.
All compartments are specially designed to hold the
above-mentioned items
(5 inserts). This makes it
easy to keep track of all
your accessories.
For optimum protection
of the calibrator and the
accessories, the compartments are designed
to hold the accessories
firmly in place during
transportation.
Switch test (Model B only)
Users may perform a thermoswitch test and find “Open”,
“Closed” and the hysteresis (deadband) automatically. The
instrument retains the last 20 test results.
Auto stepping
Up to 20 different temperature steps may be programmed
including the hold time for each step. Upon completion of
an auto-step routine, the user can read the results for the
sensor-under-test on the PTC display. Results from twenty
auto-step calibrations can be held.
The “Set temperature” feature allows the user to set the
exact desired temperature with a resolution of 0.01°C
(0.002°F).
Instrument setups
The PTC series allows the user to store up to 10 complete
instrument setups. You may store all types of information
including temperature units, stability criteria, use of external
reference sensors, resolutions, sensors-under-test (SUT),
conversions to temperature, display contrasts, etc. The
setup may be recalled at any time.
Maximum and minimum temperatures
From the setup menu, the user can select the maximum
and minimum temperature limit for the calibrator. This function prevents damage to the sensor-under-test caused by
excessive temperatures and it helps reduce sensor drift
from exposure to too high temperatures. This feature can
be locked with an access code.
JOFRACAL calibration software
JOFRACAL is a highly versatile calibration software that is supplied together with the PTC calibrator. The
software ensures easy calibration
of all kind of temperature sensors,
such as RTD´s, thermocouples,
transmitters and thermoswitches.
Furthermore, it can be used for pressure calibration i.e.
pressure gauges and pressure switches.
In conjunction with JOFRACAL, PTC calibrators can:
•Operateasastand-aloneinstrument,usingadvanced
calibration routines without the assistance of a personal computer on site. The work order functionality
•Preventunauthorizedchangestoacalibrationroutine.
Personnel who are not authorized to alter a calibration
routine cannot do so
Once all calibrations are completed, the data may be uploaded to JOFRACAL for printing of certificates. The data
collected may be stored on the personal computer for
later recall or analysis.
JOFRACAL offers extended output formats of the captured calibration data such as PDF file format and ASCII/
semicolon separated text format for further processing
and calculation of data in spreadsheets and word processors.
