Easy Temperature Calibrator ETC-series » Temperature ranges » Fast calibration saves money Heats up as quickly as 100°C / 212°F per minute and stabilizes in just 3 minutes. Completes a 2-point test in less than 10 minutes » Extreme flexibility The small size makes it perfect to store in a tool box and to check temperature sensors that are difficult to access » Fully-featured despite the small size The multi-information display shows actual and set temperatures, a stability indicator, and a stability countdown timer » Timesaving features Fast one-key-one-function access to set the temperature and the auto-stepping function » Documentation made easy Heats up by up to 100°C / 212°F per minute and completes a full dualpoint 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. RS232 communication interface and JOFRACAL calibration software are part of the ready-to-use standard delivery All JOFRA ETC units have many of the same useful and timesaving features offered in the more advanced JOFRA dry-block series. Designed for people who perform tests and verifications of temperature sensing devices in the field. This instrument is ideal when time is a critical factor and the highest accuracy is not a critical factor. Standard delivery of the ETC-400 R includes JOFRA IR-LAB software enabling the user to calibrate IR thermometers with a fixed emission factor setting » Complete marine program Part of a complete program of marine approved temperature, pressure and signal calibrators; including temperature sensors Reduced size and weight are important considerations because the unit is able to fit 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. ISO 9001 Manufacturer Specification Sheet, SS-ETC

Cooling and heating - ETC-125 A dry-block The ETC-400 R is designed for optimum speed in connection with calibration of infrared thermometers. The 36 mm target provides the optimum size for reliable calibration of infrared thermometers in the process industry as it is designed for high accuracy and long-term stability while maintaining speed. 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...

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...

JOFRACAL CALIBRATION SOFTWARE JOFRACAL calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermoswithes, pressure gauges and pressure switches. JOFRACAL can be used with JOFRA DPC-500, APC, CPC and IPI pressure calibrators, all JOFRA temperature calibrators, as well as JOFRA AMC900, ASC300 multi signal calibrator and ASM-800 signal multi scanner. STANDARD DELIVERY • JOFRA ETC dry-block calibrator • Traceable calibration certificate - temperature performance • JOFRACAL calibration software • User and reference manual • Mains power cable • Shoulder strap •...

It is not easy to make a good quality reference probe. The main requirement of a reference probe is stability. This means minimal drift as a function of operating time at the actual temperature. The less the probe drifts, the lower the measurement uncertainty. Temperature range Especially for the ETC-400 R calibrator JOFRA has designed a special 3 mm STS reference sensor, the STS103 B. The sensor can be used as a reference sensor when a higher accuracy is required or for recalibration of the ETC-400 R. Due to the small immersion depth requirement of the sensor it can be placed under the...
