Test equipment for temperature and its
reduction

■ Pt100 precision RTD temperature probe

■ Calibrated temperature measuring chain with precision display device

■ Calibrations as service (DAkkS approved)

■ Calibration measuring range -80 to +1100 °C

Increased quality consciousness, improved measuring techniques and quality assurance
systems, such as, for instance, DIN ISO 9000, strengthen the requirements regarding pro­cess documentation and measuring means monitoring.

The use of platinum precision RTD temperature probes is preferred as standard. They are
intended to monitor all temperature probes used in industry, building services engineering
and quality assurance.

In connection with a precision display unit (temperature measuring chain) the measured
temperatures can be directly read and transmitted online via the USB interface. For doc­umentation purposes, the "DE-Graph" software available as an option, allows the estab­lishment of tables and graphics as well as editing in other Windows applications.

The main criterion of all devices is the traceability of the measurement results to the na­tional standards. DAkkS (DKD)-calibrated test equipment is recognized without further in­formation as feedback instruments, both in Europe and in many countries outside of
Europe. The calibration service is available at any time for existing test equipment.

Precision display unit: Description:

These universally applicable, process-controlled indicating devices convince with highest
accuracy and are perfectly suitable for measuring tasks that require highest precision. Ap­plication areas are in the fields of quality assurance, production, maintenance/repair and
service as well as in the air conditioning and environmental technology. All devices of the
P700 series are equipped with a USB interface allowing an online documentation of the
measured values. This interface can also be used for supplying the devices with power.
The measured data can be processed further using the optionally available Windows soft­ware "DE-Graph“.

Product features:

- integrated calibration function for simple compensation of probe tolerances

- 1-stage, 2-stage or 3-stage calibration optionally possible

- USB interface

- Windows evaluation software optionally available (see accessories "DE-Graph")

-Large LCD display

- Storage of MAX, MIN, HOLD and average values

- Differential temperature display for 2-channel units, simultaneous display of both val­ues

- Mains operation possible

- Pt100 input in 4-wire circuit, thermocouple inputs as per DIN EN 60584

- Measuring channels can be freely assigned

- °C/°F change-over
