Ametek Jofra ETC-125A
Dry Block Temperature Calibrator

The Ametek ETC could be the world's fastest Dry Block Calibrator!

The Ametek Jofra ETC Dry Block heats up by up to 100°C / 212°F per minute and completes a full dual-point test in less than 10 minutes, including stability time; timesavings at your fingertips! The ETC- series is designed for field testing of temperature measurement devices. The small size and light weight make it a perfect instrument to verify sensors in difficult to reach places. All JOFRA ETC units have many of the same useful and timesaving features offered in the more advanced JOFRA dry-block series. FEATURES: Designed for people who perform tests and verifi cations of temperature sensing devices in the fi eld. This instrument is ideal when time is a critical factor and the highest accuracy is not a critical factor. Reduced size and weight are important considerations because the unit is able to fi t into a tool box or instrument carrying case and can be used for sensors that are difficult to access. One-key-one-function user interface provides immediate access to setting the temperature and the auto-step timesaving function. There is no need for manipulation of sophisticated menus. The Stability indicator provides audible and visual prompts when the temperature is stable. This function also includes a 3 minute countdown before the stable condition. Stainless steel and rubber side panels make the instrument suitable for many years of faithful duty in an industrial environment. Cooling and heating - ETC-125 A dry-block - The ETC-125 A is a simple yet effective tool for verifying temperature instruments that also require references below ambient temperatures: e.g. air-conditioning and cold counters. The predrilled holes allow the use of an insertion tube in the largest bore. This increases the flexibility to match many sensor-under-test sizes. Easy-to-use, intuitive operation - All instrument controls are accessed directly from the front panel. The main functions on the ETC- series are designed with one-key-one-function logic. This means that there are no difficult multiple keystrokes to remember to access primary functions. The easy-to-read, backlit display features dedicated icons, which help in identifying instrument conditions and operational steps. Set temperature - The Up and Down arrow keys allow the user to set the exact temperature desired with a resolution of 0.1°C or °F. Stability indicator - The bold checkmark on the display indicates that the calibrator has reached the desired set temperature and is stable. The operator may change the stability criteria and establish a greater level of confidence in the calibration results as desired. A convenient countdown timer is activated three minutes before the unit reaches stability. This prompts you to be prepared to record results. Auto-stepping - This feature saves time. The operator may stay in the control room, or another remote location, monitoring the output from the sensor-under-test while the ETC- series calibrator is placed in the process and automatically changes the temperature using a programmed step value and rate. Up to 9 different temperature steps may be programmed, including the hold time for each step. This feature is also ideal for burning-in new sensors prior to installation; this minimizes initial drift and allows for initial testing. It is also useful for testing temperature data loggers. Maximum temperature - From the setup menu, you can select a lower maximum tempe-rature limit for the calibrator. This function prevents damage to the sensor-under-test caused by the application of excessive temperatures. Instrument setups - The ETC-series stores the complete instrument setup, including: engineering units, stability criteria, resolu-tion, auto-step settings, and maximum temperature. Re-calibration/adjustments made easy - The ETC- series has a very easy and straightforward procedure for re-calibration/adjustment. There is no need for a screwdriver or PC software. The only thing you need is a reliable reference thermometer. Place the probe in the calibrator and follow the instructions on the display. Simplified calibration documentation All JOFRA ETC- instruments are supplied with RS232 computer interface and the calibration software AMECAL-LIGHT for on-line use. This WINDOWS ®-based software allows the user to customize his or her calibration routines. The software is easy to use so you do not have to be a programmer to configure your own calibration procedures. After calibration you can print out certificates that contain all necessary information for your ISO-9000 or similar quality systems. The ETC calibrator can also work with the larger AMECAL-TEM-PERATURE software, which supports automatic calibration for all JOFRA dry-block calibrators equipped with an RS-232 serial data interface including the JOFRA DTI-1000 digital thermome-ter. For semi-automatic calibrations, the software also supports liquid baths, ice points, or other dry-block heating and cooling sources. Using the software's »SCENARIO« function allows for combining instruments in virtually any configuration.
