Ametek Jofra ASC 300
Advanced Signal Calibrator

The Ametek ASC Calibrator in Action !

The Ametek Jofra ASC 300 is substantial enough to cover all your needs for a process signal calibrator with superior accuracy and compact enough to fit into your tool box and operate with one hand for easy field calibration. The ASC300 can change your entire calibration regimen for signal, pressure, and temperature. You can combine this versatile calibrator with the JOFRA APM external pressure modules or a JOFRA dry-block calibrator to meet your calibration needs. The JOFRA ASC300 combines a full numerical keypad with a series of function keys and a graphical user interface making it easy to perform various tasks in a short period of time. This advanced calibrator employs the latest technology in supporting your calibration needs. The JOFRA ASC300 measures and sources: TCs, RTDs, current, voltage, frequency, and pulse trains. This instrument is also designed to be compatible with the JOFRA APM pressure modules and thus offering true multifunction operability. There are two channels of operation providing the user with an isolated read-back circuit. The graphical display makes it is easy to recognize the status of the instrument, take readings, and simulate different functions. The JOFRA ASC300 has full fuseless protection to 240 VAC, which is an important feature as most signal calibrators fail due to over-voltage during use. The JOFRA ASC300 offers simutaneous input and output. This means that you can calibrate and adjust a temperature transmitter on the table with no other necessary instruments. Output the sensor signal and input the mA from the transmitter. If you select mA Loop the JOFRA ASC300 will also supply the 24 VDC for the loop. In the display you will see both your output temperature and the return mA from the transmitter. Enter the zero and full scale values and you can make quick 25% steps or go direct to zero or full span values. The JOFRA ASC300 has dedicated keys for this operation so adjustment on the transmitter is made easier. The JOFRA ASC300 contains a very useful fuseless protection feature. The most common mistake is to connect the instrument to an AC supply - this normally means that you will have to send the instrument for an expensive repair and re-calibration. This is not the case with the JOFRA ASC 300. This instrument is protected for up to 240 VAC on any combination of connections made on the test lead connectors. Just remove the test leads and the instrument is ready for operation after only 10 seconds. The soft case that protects the instrument is engineered so that it becomes a useful part of the instrument. The soft case is designed for easy vertical operation so that when you open the case you will have easy access to all your test leads in the pocket. A fl ap in the top and an opening in the bottom provide access to the termination block and the pressure module connector. The soft case includes a shoulder strap for convenient transportation of the instrument when climbing ladders, etc. At the back of this case you will also find a handy strap that fits your hand or makes it possible to hang the instrument on a pipe, ladder or the like while performing the calibration, test, or service task. The JOFRA ASC300 offers the possibility to charaterize an RTD sensor. Use this feature to add a missing special curve or to characterize a reference RTD. If you choose a reference RTD from the JOFRA STS100 series of high accurate and stable temperature sensors, they will be delivered with a traceable calibration certificate including the neccessary Van Dusen coefficients. Enter the figures into the JOFRA ASC300 and you have a temperature reference. Complement this with a JOFRA dry-block temperature calibrator and your JOFRA ASC300 becomes the heart of your portable calibration lab.

The APM series of pressure modules offer the flexibility to perform pressure calibrations with the ASC300. Select from over 60 remote pressure modules for your APC calibrator. See our complete selection by Clicking Here. Independent of the engineering unit of the module you can change units on the ASC300 (11 different engineering units) at any time. These rugged modules are engineered for both field and laboratory use. They are ready to use with the JOFRA calibrators and the protocol allows for immediate recognition and use of the module once it is plugged into the calibrator.
