Ametek Jofra PTC-425 professional dry-block temperature calibrator is a versatile temperature calibrator with a range of +33°C to +425°C (+91°F to +797°F) and is used in various sectors such as healthcare, medical, pharmaceutical, biotechnology and food industries
There are three models of the PTC-425 these include.
The PTC-425 calibrator provides precision temperature calibration of sensors, what-ever the type or format. This is accomplished through an innovative active dual-sone heating technology.
With the active dual zone 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 eliminates the need for extra insulation of sensors-under-test and makes it possible to calibrate liquid-filled and other mechanical sensors.
The USB connection facilitates easy communication with JofraCal. The USB connection also supports easy to download of future firmware upgrades. The USB connection provides fast and easy access to all laptops without the need of RS-232 to USB converters.
Future-proof through e.g., a flash capability for easy firmware upgrades as well as LAN communication, SD-card slot, and USB host connectors for future use.
The Jofra STS-200 intelligent reference sensors contain individual calibration data regarding the sensor. Firstly, this means the time-consuming coefficient downloading sequence with risk of errors is no longer necessary. Secondly, the user can change the reference sensor and be up and running immediately. With intelligent sensors a source of error has been eliminated and the system is now given a fail-safe plug n’ play calibration system.
The STS-200 reference sensors have been designed with a 90° angle and fit the calibrator so that they are only slightly higher than the top of the PTC calibrator. The design makes it possible to calibrate threaded sensors and sensors with connection heads without any problems.
The PTC calibrators have an increased heating and cooling speed compared to all other calibrators. Heating and cooling speeds have been increased by up to 20%. This implication is savings in both production downtime and general calibration costs.
Two special multi-hole insert kits are available to comply with the calibration of almost any sensor diameter without having to buy numerous inserts.
The first kit a metric insert kit consisting of only four inserts covering all diameters from 3mm to 12mm. The other is an imperial insert kit consisting of three inserts covering six different sizes from 1/8” to 1/2”.
All inserts have holes for both STS reference sensors.
The carry case is designed to store both the STS sensors in the carry case with optimum physical protection. There is room for inserts and insulation plugs for cover all dimensions and compartments for the integrated support rod set, wires, manual, certificates, plugs, inserts tools etc.
All compartments are to hold one of the above-mentioned items. This makes it easy to keep track of any accessories. The compartments are designed to hold the accessories fixed during transportation.
In order to comply with ISO, SOPs and FDA it is imperative that the calibration equipment never exceeds the expiry date of the calibration certificate. When switched on the PTC calibrator constantly checks calibration dates on the calibrator as well as connected STS sensors. If the calibration period has expired, a warning will appear on the display. This feature prevents costly consequence evaluation.
The 5.7” full colour VGA display is very is to read. 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 logical to use. The display shows any important information needed for the current function in use. The communication windows pop up and are followed by discrete sound messages. The display is very bright, and the main information can easily be read form a distance. The advanced simplicity PTC user interface is available in English, German, Chinese and Japanese.
The large display contains more information at a glance, such as:
JofraCal is a highly versatile calibration software that is supplied with the PTC calibrators. The software ensures easy calibration of all kinds of temperature sensors, such as RTD’s, thermocouples, transmitters and thermoswitches. JofraCal may be used for manual calibrations, as it can be set up to accept manual entry of calibration data together with other liquid baths, ice points, or dry-block heat sources.
The calibration data collected can be stores on a PC for recall at a later date. The PTC calibrator stores the calibration procedure and may be taken out to the process site without the need of a PC. This allows the PTC calibrator to:
Once all calibrations are complete, the data may be uploaded to JofraCal for the printing of certificates. The data collected may be stored on the PC for later analysis.
JofraCal offers extended output formats of the captured calibration data such as PDF, ASCII / semicolon separated text format for further processing and calculation of data in spreadsheets and word processors.
JofraCloud is a new way to perform remote reading and setting of PTC temperature calibrators over unlimited distances, with transmission coverage equal to that of a smartphone.
The data is presented as a copy of the calibrator’s display and can be viewed on a PC, laptop, tablet or smartphone at jofracloud.com
Once attached to any PTC (or RTC) calibrator, the gate-way reads data every 2 seconds and allows you to print a timestamped pdf as documentation.
