Price Request

The 7000 is a portable process calibration instrument that combines a precision digital thermometer (using RTD probes) with an RTD/ohms calibrator.

Compact and easy to use, it solves the problem of making high accuracy temperature measurements without using bulky mains powered instrumentation.

Powered from internal long life rechargeable batteries or an external mains adaptor, this RTD temperature calibrator is equally valuable in the laboratory, workshop or field.

It can also be used as an external temperature reference for dry block calibrators and other precision temperature baths.

Technical Specification

Monitor Mode (4 wire)
Typical Functions	1. Check RTD probes by measuring their resistance at known temperatures. 2. Measure resistance values. 3. Indicate temperature when connected to an RTD probe. 4. Can be pre-programmed with a particular RTD’s characteristics to allow very high accuracy.
Excitation current	1 mA on all ranges
Resistance range	0.01Ω to 2.6 kΩ
Resolution	0.01 Ω
Accuracy	See specifications below
Auto re-calibration	Every 0.6 secs
Temperature stability	Better than 0.0015 % per °C
Max/Min values	Logged automatically
The 7000 may be used with a calibrated and certified probe to produce a highly accurate thermometer. The performance can be further enhanced by programming the actual characteristic of the probe into the unit.

Simulator Mode (4 wire)
Typical Functions	1. Output resistance of precise known value. 2. Simulate an RTD value from an RTD table chart. 3. Simulate an RTD value using the internal table.
Excitation current	0.6 mA to 1 mA
Resistance range	0.01 Ω to 2.6 kΩ
Resolution	0.01 Ω
Accuracy	See specifications below
Auto re-calibration	Every 0.6 secs.
Temperature stability	Better than 0.0015 % per °C
Enhanced performance may be achieved by programming the unit to simulate the characteristic of a particular probe. Five fixed step points (0, 25, 50, 75, 100 %) are available between a user set minimum (0 %) and a maximum (100 %). Programmable ramp function is also available.
